Configure the Outstation using a handset terminal connected to the 25-way 'D' 
type connector, SK1, on the PCB. See section 3.3.3 for an explanation of 
commands that need to be entered. 

 

If required the wiring of OTU inputs and outputs (cable 667/1/22693/000) can be 
checked as follows:  

 
Checking OTU Output wiring: 
Attach a handset to the controller and enter controller handset commands 
that display the status of the 16 controller inputs. Attach a handset to the 
OTU and enter handset commands to set different output bit patterns on the 
OTU outputs. Ensure that the controller inputs displayed on the handset
