– 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.

Description 

+12 Volts 

12 Volt supply to Paylink Lite 2 

0 Volts 

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.)
