Set the serial data rate to 38400 ATC6

Set the radio data rate to 19200 not necessary (default)

Set the character type to 7,1,2,even AT&B13

Exit and save the configuration AT&W ATO

The operating mode will already be in transparent mode from the factory default settings. The

other default values for the other parameters will likely be OK.

Repeater Configuration

Set the module to factory default settings: AT&F

Set the system address to the same random number: AT&S138

Set the group address and unit (secondary group) address AT&G1 AT&U2

The group address for the right hand side module will be set to 2 (this corresponds to the

secondary address of the repeater).

Note that the repeater will only output data to its PLC for messages received from the first 905U-D. It

will not output data from the right-hand PLC. If you set both group addresses to 1, then the repeater will

output data from both sides - this is only possible when there is only one repeater. The disadvantage of

this is that both sides will hear the re-transmitted message - that is, the PLC that sent the message will

receive the same message back as a re-transmitted message. This is not a problem with most PLC’s, but

is with a small number of brands. For these brands, use a different group address either side of the

repeater.

Set the serial data rate to 9600 ATC4

Set the radio data rate to 19200 not necessary (default)
