TC12 Installation, Commissioning & Maintenance Handbook 

Set the Mode switch to the CONTROLLER position. (If the connection fault is lit 
return the switch to OFF and check that the plugs are fully inserted before 
proceeding). 

 

Set up the required patterns for words 0 and 1 output to the desired 16 inputs of 
the OTU. The OTU responds to the data and transmits reply bits back to the 
Instation. The LED indicators on the OTS display the control data from the 
Instation. The transmission confirm indicator should be ON. (The transmission 
confirm switch is not used in this mode). 

 

Repeat 5 as required. 

 

If the transmission confirm indicator is not lit no data is transmitted from the 
OTU. 
 

With the equipment set up as described above the operation of OTU 
Inputs/Outputs can be checked: 
 
Checking that OTU Outputs are working 
Connect a handset to the OTU. Enter OTU handset commands to set the 16 OTU 
outputs. Check that the appropriate LEDs display the status of the outputs as set 
on the handset. 
 
Checking that OTU Inputs are working 
Enter OTU handset commands to display the status of the OTU inputs. Set 
different patterns on the OTS data switches and check that these are correctly 
displayed on the handset.
