1. Introduction

Thank you for choosing a P6X Series Payment Terminal for your application. These terminals are designed for use in unattended points of sale such as Food and Beverage vending machines or parking ticket machines, that require no PIN. With the objective of creating a cost efficient multifunctional payment terminal, a P6X Series Terminal can support many payment schemes and a large variety of host applications.

The Terminal can be used as a drop-in replacement for your existing application using industry standard interfaces such as Multi Drop Bus (MDB) or potential free pulse contact. Also available are proprietary interface options (RTP, PVP), that uses either Ethernet, USB or RS232 to connect the P6X terminal using a payter proprietary protocol.

An internet connection, required for transaction processing, can be provided to the terminal by connecting to a LAN network. If no LAN is available, an optional 3G/HSPA Modem can provide a high-quality internet connection, ensuring your transaction processing performance will not degrade because of a low internet speed.

The P6X Terminal series support reliable remote management functionality for firmware updates and configuration changes. It is highly recommended that you always leave your terminal on and connected to the internet, to ensure that your it can be managed properly.

2. Document Scope

This manual is intended for technicians or operators that want to familiarize him/herself with the functionality of the P6X Terminal Series. The Terminals that are discussed in this document are the P68 The Arc, and P66 The Plane. The two terminals have Quite similar functionality, and where applicable the differences are explained in the relevant chapters. It is also a good starting point for developers and integrators who intend to integrate the a P6X terminal in their(vending)Machine, although additional documents would be required, and are available upon request.

3. P6X Terminal Overview

3.1 P68 3in1 terminal

3.2 P66 Contactless Only Terminal

3.3 P66 Split Build on Top terminal

The P66 Split is the ideal solution for machines which has minimum space to integrate a terminal such as snack walls and toilets. P66S is identical to the P66 terminal with the exception that the card reader and the communication is split into two parts. The card reader can be mounted on top of any machine, while the communication unit is located inside the machine

4. Basic Connectivity Features

Fig. 4 - Connectivity Diagram

4.1 Host Machine Interface

The P6X terminal series support several different interfaces to connect to your host machine. Choosing an interface will largely depend on the interface that is supported by your machine, and the preferred method of powering the terminal. Table 1 gives a summary of available options.

4.2 Internet Connection

For most applications, involving a P6X terminal, a stable internet connection is required, the available options described in table 2.

4.3 Terminal Configuration

The Terminal configuration covers multiple aspects that need to be configured before a successful transaction can be performed. Most of the settings are determined when a terminal is ordered for a specific Payment host provider. Settings related to a terminal interface mode or network communication are usually set correct by default, in some cases settings have to be modified for the terminal to function properly.

5. Payment Flow

5.1 Description

A Host machine is always responsible for initiating a payment on the terminal, the only exception is Auto Scan mode. This chapter describes how a payment is performed by a user, and how to interpret the feedback that is given by the terminal. Some operational modes can introduce a slight difference in this behavior, these details will be covered in chapter 6 for each respective mode, if applicable.

5.2 Accepted Card types

The P68 terminal accepts one of these three card types, from any of the configured payment schemes to perform a payment. The P66 terminal is a contactless payment only terminal and therefore only accepts Contactless Cards and Mobile phones. The terminal can also accept proprietary card types for example for loyalty applications, or a closed user group application.

Card Type	Description
Contactless Card/Mobile phones	When prompted to do so, tap the Card or Phone with NFC on the Contactless Symbol on the front of the terminal. Keep the Card in place until the terminal indicates that the card can be removed.
Contact Chip Card	Insert the Chip Card in the illuminated card slot. Do not remove the card until you are prompted to do so.
Optional SAM	The SAM module contains cryptographic key material that is needed to set up a secure connection, and authenticate the terminal, with the payment service provider
Magnetic Stripe Card	The user can swipe a magnetic stripe card through the swipe slot as indicated on the P68 terminal.

Table 8 - Accepted card types

Fig. 5 – Accepted payment types

5.3 Transaction & Display messaging

When the host machine initiates a transaction, the following display message will prompt user to pay on the terminal:

Fig. 6 – Initiating transaction.

*1 P68 only functionality

Some messages may be presented differently for different payment service provider, but in essence the pay flow is the same.

6. Modes of Operation

6.1 MDB mode

6.1.1 Description

The majority of the Vending Machines support the MDB or Executive communication protocol.

MultiDrop Bus (MDB)

"The multidrop bus used by vending machine controllers to communicate with the vending machine's components, such as currency detector, is also called MDB. In use since the 1980s, it is now an open standard of the National Automatic Merchandising Association, or NAMA."

In general:
The payter Vending terminals will support all Vending Machines that comply with the MDB specifications. Level 1-3.

This mode of operation is commonly used for vending machines.
The vending machine controller(VMC) and the terminal are physically connected using a single cable for power and communication. The VMC is the BUS master and instructs the terminal what to initiate a transaction.

All electrical and detailed aspects are covered by the MDB standard, this simplifies the integration of the terminal to a plug and play experience. With only a few settings that require attention. The terminal is classified as an MDB Cashless Device, and supports Level 3 functionality including "always idle mode" from the MDB specification v4.2.

For a detailed description on the MDB interface, consult the MDB v4.2 specification documentation.

6.1.2 Connecting the terminal

Note: Always Turn off the vending machine when installing a new MDB device!

Connect the P6X terminal to the VMC using the supplied MDB Cable. Power up the vending machine, the terminal should power up as well. After boot-up has completed the terminal should automatically register with the VMC.

6.1.4 Applicable Settings

The following behavioral settings require attention in MDB mode:

Fig. 8 – MDB settings

6.2 Executive Mode

6.2.1 PROTOCOL A (EXECUTIVE)

“Also known as Executive, this protocol was developed by Mars Electronics International in the early 1980's to interface peripherals to electronically controlled vending machines. The definitive Protocol A specification is produced by Mars Electronics International.”

Support for the MDB comes standard with the payter terminal in case the Vending Machine only supports the Executive protocol an additional converter (payter VendBox) is required which can be placed in between the terminal and the Vending Machine

6.2.2 Vendbox

The Vendbox acts as a bridge between the Executive vending protocol, and the MDB protocol, and is designed to be used in combination with a payter contactless terminal. When connected to an Executive vending machine, the Vendbox acts as the Executive Master and delegate commands to the Vending Machine Controller (VMC). It will also act as MDB VMCand send vend requests to the MDB cashless device connected to the MDB bus.

For detailed specifications and installation instructions, please refer to the Vendbox manual

6.2.3 Applicable settings

The terminal will be configured as a regular MDB device, see previous chapter

6.3 Potential Free Pulse Contact (Autoscan mode)

6.3.1 Description

Connecting a P6X Terminal to existing, coin mechanism only, applications can be challenging. To be able to integrate a P6X Terminal in these existing applications, a potential free pulse contact was added to the terminal features. Allowing the terminal to replace the coin mechanism or be used in parallel.

A potential free pulse contact can signal a host machine that a payment was performed successfully, the concept is similar to a pulse output on a coin mechanism interface. In addition, a P6X terminal has an inhibit input that can be used to enable/disable payments on the terminal, for example when the Host machine is out of order

6.3.2 Connecting the terminal

Implementing this mode of operation requires attention to electrical details to which this interface is bound. The pulse output is highly configurable in polarity, pulse width, pulses per transaction etc. For a detailed description of the potential free pulse contact features, please inquire with your local supplier about “Pulse I/O” documentation. This documentation describes the electrical properties and the settings that are important for integration with your device.

6.3.3 Pay flow

When the terminal is powered up, it will automatically start scanning for cards. Every time a card is presented, a transaction is performed for the indicated amount, and a pulse is given for each successful transaction. It is the responsibility of the host machine to capture all the pulses that are send by the terminal. When the host machine is not able to capture pulses or provide the service for which is to be paid, the terminal should be disabled. By either powering down the terminal or through enabling the terminal inhibit input. When the host machine functionality is restored the terminal can be enabled again to resume operation.

6.3.4 Applicable Settings

The following settings control the behavior of the Autoscan Pulse Contact mode.

6.4 RTP Mode

6.4.1 Description

The Remote Terminal Protocol (RTP) is a proprietary protocol used to interface with payter terminals from host systems such as Cash Registers or other PC applications. To integrate the P6X Terminal functionality in your application, a dotNET SDK is available that can be used to perform transactions.

Fig. 11 - RTP mode of operation, over either LAN or USB

This mode of operation is very specific and dependent on how the P6X Terminal is integrated in the host machine application. Refer the host machine documentation for operational details. Refer to the dotNET SDK documentation on a detailed description how to integrate the terminal in an application.

6.4.2 Applicable Settings

RTP settings are covered in the RTP documentation.

6.5 CCI Mode

6.5.1 Description

Some Coffee machines are equipped with a CCI interface this interface is a message based protocol over an RS232 connection, that enables the communication of certain types of coffee machines with a P6X terminal.

6.5.2 Connecting the terminal

Always power off the host machine and terminal when connecting the RS232 Cable to the terminal and the host machine devices. Power up the machine and the terminal, make sure the correct payment device is selected in the host machine.

6.5.3 Pay flow

CCI protocol is not able to notify the terminal that a vend was successful/unsuccessful therefore transactions cannot be canceled.

6.5.4 Applicable Settings

The following settings control the behavior of the Autoscan Pulse Contact mode.

6.6 PVP Mode

6.6.1 Description

The payter vending protocol is a message based protocol over a RS232 connection, that allows basic functionality needed for vending machines and terminal communication. It can handle scenarios most common for vending machines. Refer to PVP documentation for in depth information about this interface.

6.6.2 Connecting the Terminal

Always power off the host machine and terminal when connecting the RS232 Cable to the terminal and the host machine devices. Power up the machine and the terminal,

6.6.3 Applicable Settings

7. Setting Up Internet

An internet connection for a P6X terminal is necessary to perform features such as online verification of payments, remote management functionality or telemetry

During boot the terminal will check the connection to all configured payment host. If during this check the payment host cannot be reached an error will be displayed indicating which host was not reachable. This must be resolved before regular operations are attempted with the terminal

The following options are available to connect to the internet.

7.1 LAN connection

a P6X terminal can be connected to a LAN network using the onboard Ethernet port, with either a dynamic or static IP address. The available LAN infrastructure is used by the terminal to connect to the internet. The Firewall settings should allow the terminal to connect to the PSP and other destination host addresses needed for correct functioning. This type of internet connection is preferred and when the infrastructure is optimally configured, the best transaction performance can be achieved.

7.1.1 Applicable Settings

GPRS/EGDE/3G/HSPA MODEM

When no LAN connection is available a mobile internet connection can be established with an optional 3G/HSPA modem. A HSPA network connection allows a good transactions processing performance. In case the 3G/HSPA network service is not available a 2G fallback mechanism is in place, but at a cost of transaction performance.

As part of the MODEM option a suitable antenna, is supplied with the terminal. The antenna performance should be satisfactory for most applications, provided of course there is sufficient coverage of the network operator. It is encouraged that a signal quality measurement is performed at the intended installation location. Antenna mounting position and location is key in achieving a good signal quality. Place the antenna on top of your application/vending machine, not inside, the metal surroundings will degrade the signal quality.

7.2.1 Connection Setup

The modem option is installed during manufacturing and cannot be installed by a user. Always remove the power from the Terminal before accessing the modem compartment, or when removing/placing an antenna. Remove the hatch on the back of the terminal labeled “MODEM” to access the MODEM compartment. This allows access to the SIM Card Slot. The Antenna can be connected to a dedicated connector on the back of the terminal For the modem to connect to a mobile internet service properly it needs a data SIM with internet services enable. The data SIM can optionally be ordered with your terminal, it is also possible to use your own data SIM card, provided you configure the correct APN settings for accessing the local network.

The bars show the signal strength of the 3G/HSPA connection. When the terminal is connecting the ‘i’ will be blinking. As soon as the ‘i‘ is on the connection has been established with the 3G/HSPA network and the modem is working properly.

Fig 16 – Signal strength icon

7.2.2 Applicable Settings

Setting	Description
GPRS Enabled	Enables/Disables Mobile Internet, only if the option is already installed.
APN	The Access Point Name is provided by the Mobile internet provider.
User	Provided by Mobile internet provider
Password	Provided by Mobile internet provider
PIN	Use this setting only when the SIM is configured with a PIN Code. If no PIN is configured on the SIM this setting has no effect. It can be useful to configure no PIN or PIN 0000 on the SIM cards to avoid having to configured this code individually on each terminal. Note that the terminal will attempt this code at each boot. If not configured correctly this may block the SIM card requiring it to be unlocked using the secondary PIN (PUK) code.

When successfully connected to the terminal the settings, under different tabs, become available for editing. Refer to the respective interface mode chapter for the settings under each mode.

9. Dimensions & Mounting

The majority of the Vending Machines have a provision for installing Payment Terminals. The dimensions of the P6X Terminal series are based upon the EVA (European Vending Association) standard.

9.1 Device opening

Mounting a P6X terminal series requires a device opening that complies to the EVA EPS – Standard door model measurements (Fig. 19).

If no weld studs are available an optional mounting frame, with weld studs, can be ordered. Drill mounting holes of 4 mm on the same positions as the indicated weld studs to allow mounting of the frame.

9.2 Mounting options

Installation option 1:

In case no weld studs are provided as indicated in Fig 19, payter can provide a mounting frame which can be secured through 4mm mounting holes, located at the indicated weld stud positions.

Metal environments will influence the performance of the contactless operating field. Please ensure that the P66 terminals are not completely enclosed in a metal environment otherwise the operating distance will be reduced. An offset of 5 mm along the sides and rear of the terminal will provide enough distance. If you have any questions with regards to the mechanical integration, please contact the payter support desk.

Installation option 2:

In case the vending machine comes with pre-installed studs the mounting frame is not required. An additional cover plate can be ordered for a clean finish of the front. The cover plate is secured with double sided adhesive for a strong connection.

9.3 Dimensions P68 The Arc

The thickness of the Vending Machine or cabinet should not exceed 10 mm to ensure a proper magnetic stripe card swipe.

TROUBLE SHOOTING

Problem	Solution
	GPRS/GSM Connection
--- Icon blinking No GPRS signal	Verify whether SIM Card is placed Check whether SIM is activated with the provider Verify that external antenna GSM/GPRS is connected Check whether the antenna is not cased in a metal environment with No reception, check antenna placement outside the vending machine
'i' does not appear	Reception is fine but the terminal is unable to make a connection Check the following settings using the Vending settings tool: GPRS APN GPRS User GPRS Password GSM PIN code If a dedicated APN is used, please verify with the provider whether the required urls are accessible
Low reception GPRS	GSM / 3G / 4G reception does not automatically indicate GPRS reception. Verify with local network settings which network (2G/3G/4G/GPRS) has the best results. Using a different provider can improve reception sometimes. You get the Most Consistent & Reliable Results by placing the antenna on top of the vending machine. An optional External Mount Dome Antenna can be provided to help with Performance & Security Things to consider: There is usually more reception between our antenna and the antenna on the cell tower They do not go around obstacles, they go through them if they can Glass and wood are no problem but steel and concrete pose a real challenge Consider heating ducts, plumbing and other such obstacles
	LAN CONNECTION
No connection	Check LAN cable and link, LEDs should be blinking on terminal LAN connector. If not check Cable and patch outlet. Solution should be working whether DHCP or static IP Validate firewall rules with the Local IT administrator Verify whether below ports and URLs are accessible: Terminal Management System –curo-api.payter.nl (port 3185) Transaction processing Equens – https://89.221.178.190:1445 Transaction Processing Elavon –https://live.cardsecurity.net:443 Transaction processing CCV –https://oltp.ccvpay.nl (port 10037) If DNS plays a role successful name resolution should be enabled by the IT administrator please try 8.8.8.8 or 8.8.4.4 (Google DNS servers). Whether DNS resolve is successful or not, the IT administrator should be able to ping the terminal through the network.
	Other possible problems
	If the MAC address is required for the firewall, it can be obtained through Vend Settings tool. To verify whether the problem is network setup, let IT administrator often clonning: Connect a laptop using the same cable, outlet and network settings and using a browser try to connect to the URLs listed. Connection is Expected fail outputs are incorrectly classified / parsed. On occasion, it happens that outlets are incorrectly labeled/patched. There are cases where IT administrators change the IP address of the hosts instead of using the url's. This is not recommended as Payment though would be through services which would result in no connection.
