1 Introduction
The Paylink Lite 2 family comprises a set of interface boards, primarily
intended to allow the connection of money handling peripheral equipment to
PCs running a Windows operating system or Linux.
At time of writing, the Paylink Lite 2 family currently comprises the following
boards.
ccTalk Standard
RS232 Standard
Paylink Lite 2 is designed to interface either RS232 money handling
peripherals or ccTalk peripherals to a PC.
An MDB interface variant is currently being considered, but is not available.
All variants of the Paylink Lite 2 have onboard circuitry designed to prevent
“hanging” of the PC USB electronics due to noise.
This document serves as the user manual for the ccTalk Paylink Lite 2.

1.1 Intended Audience
The document is intended as a product description to engineers intending to
use the Paylink Lite 2 in their equipment.
The document gives full descriptions of the operation and physical
connections to the ccTalk Paylink Lite 2.
A description of the high-level Paylink Applications Program Interface (API) is
outside the scope of this document, but see section 1.3, “Document
References” for the document describing the Paylink API.

Altered pin definitions of the 20-
pin digital I/O connector to match
the documentation of other
Paylink boards.
1.3 Document References
The Paylink Lite 2 family of interface boards implement a subset of the full
Paylink API.
This API provides high-level, device-independent control of money handling
peripherals and digital I/O signals.
Use of this API means that the machine manufacturer’s software engineers
have no communication protocol software to write. Instead, they make high-
level calls into the API, that provide all necessary information regarding the
arrival of cash and control of payment devices.
The description of the Paylink API is outside the scope of this document.
This document is therefore intended to be read in conjunction with the
standard Paylink reference documents.

3 Board Layout
The ccTalk Paylink Lite 2 circuit boards appear as in the following diagram.
Each connector will now be described in its own section, followed by a section
describing the onboard LED operation.
Note that although a power connector is provided, most of the electronics on
the Paylink Lite 2 board will operate from the USB power supply.
Thus, even though the onboard LED is illuminated, this does not necessarily
mean that the board is correctly powered.

3.1 J0101 –Power Connector
The power connector on all variants of the Paylink Lite 2 is a two-pin JST
connector. This should be connected to a twelve volt supply.

0 Volt supply to Paylink Lite 2
This 12 Volt supply is primarily used to supply power to the (12 Volt) ccTalk
peripherals; the 12 Volt supply passes through a 3A fuse and is made
available at the ccTalk connector. See section 3.4, “J0501 –ccTalk
Connector”. It is also connected to allow simple supply to the digital outputs. If
neither are in use, then there is no need to connect this.
For RS232 this can be connected to a suitable power supply for use in
supplying digital outputs. If no outputs (or only LED outputs) are being driven,
then there is no need to connect this.)

3.2 J0102 –Digital I/O Connector
The pinout of the I/O connector on all Paylink Lite 2 boards is the same.

In order to maintain compatibility with
earlier versions of Paylink, the pin
allocation of this connector is as
shown in the diagram to the left.
Note that this does not match the pin
allocation described in the Molex

3.2.1 Input Signal Operation
A switch across an input and its corresponding ground reference will be
detected by Paylink Lite 2.
3.2.2 External LED Driver Operation
The board is designed to drive LEDs directly, using the USB supply. The
current limit resistors fitted to each board are such that a nominal 10 mA is
supplied to each LED when the output is driven.
To attach an LED, the Anode (+) of the LED should be connected to an
appropriate “Pull Up” (on pins 9, 10, 11 or 12) and the Cathode (-) of the LED
should be connected to the drive output (on pins 5, 6, 7 or 8).
3.2.3 Output Signal Operation
Each standard output is designed to drive a maximum 100 mA, non-inductive
load.
3.3 J0201 –USB Connector
The connection from the PC to the Paylink Lite 2 board is though a standard
“Type B” connector.
Although an entirely standard connector, for completeness, its pin out is
included here.

3.5.1 Connecting to a 9-Pin Male D-Type
A common connection standard for RS232 peripherals is for the peripheral to
be fitted with a 9-way, female, D-Type connector.
Thus a cable from the Paylink Lite 2 to a male D-Type is commonly required.
This needs to be wired as follows:
