Connectorization At Display - Hatteland JH 19T01 MIL User Manual

Serial Communication (SCOM) Interface
Connectorization at Display
The display provides two or one 9 pin D-shell with socket contacts (depending on model).
Pin assignments at the display are as shown below.

For full duplex RS-485 , the receive and transmit pins can be altered at COM2. That is: Tx- at pin 2,
Rx+ at pin 3, Tx+ at pin 7 and Rx- at pin 8. This can be done to simplify connections, as only one to
one cables are needed throughout an installation of several Displays. The alteration is selected by a
slide switch on the Remote PCB labelled "one to one" and "rx to tx".
