MODULE FITTING INSTRUCTIONS
Beware of ESD! Observe anti-static handling precautions—avoid touching the
electronic devices on the circuit board, ensure any static build up is
discharged to earth before handling the module.
This can be achieved by ensuring the console is connected to the psu and the
psu is plugged into a mains outlet but switched OFF, then touching a metal
part of the console panel such as a screw head.
Remove the blanking panel at the rear of the console by removing the 4 screws.
Locate the module circuit board in the plastic guide slots within the housing.
Slide the module into the housing and push firmly to insert the module
connectors into the console connector sockets.
Re-fit the 4 fixing screws to the module panel. 
To remove the module for any reason, the easiest way is to unscrew and remove the fixing screws at each end of the panel then use the D Sub cable connectors to gently pull out the module. A small side to side rocking action will help to displace the circuit board connectors from the internal mother-board.
25 PIN DTYPE CONNECTOR PINNING
Analogue Input & Output 25 way D connector pin ident. 
Pin assignment (Input or Output connectors)
