Details on interconnecting various types of telemetry receivers and termination of the RS-485
line can be found on
figure 2
.
Telemetry Receivers Series BDR-51X and BDR-55X and the BED-108 Control Signal Distributor
Unit will terminate the RS-485 properly by themselves when installed in the correct daisy chain
configuration and do not require additional line termination. The ICU, SATURN and the
BDR-575 are bus-connected and consequently the line must be terminated, on the ICU with an
external resistor, on the BDR-575 by enabling the RS-485 LK1 jumper on the interface board,
and on the SATURN by setting a link across J9.
For more details, please refer to the documentation for the specific Telemetry Receiver.
Different types of telemetry receivers can also be mixed on the common control line.
Remember, that each telemetry receiver must have an unique address, refer to the relevant
telemetry receiver manual.
Maximum cable length is 1200 metres. However, telemetry receivers Series BDR-51X and
BDR-55X as well as the BED-108 features an active control signal repeater allowing further
3000 meters (BDR-51X further 1200 meters) distance to the next unit.
RS-232-C connection to E-Mux Multiplexer
