Appendix A- Receiver Configuration

BAE Systems WJ-8723

• The WJ-8723 must be configured to operate and communicate with the NRC units. This

is achieved by configuring the WJ-8723 DIP switches A2S1 and A2S2

7, 8

to:

o set the receiver mode to SINGLE-DROP mode

set rocker switches 1-5 of DIP switch A2S2 to 1

o set the serial communications to 19,200 bps

set rocker switches 1-3 of DIP switch A2S1 to 1,0,0 respectively

• Once the receiver switch settings have been adjusted, cycle the receiver power for switch

settings to become active.

• Be sure to use the BAE Systems WJ-8723 correct control and audio cables.

• Connect the control cable from the RS-232/CTL port (D25F) on the receiver to one of the

NRC’s COM ports (RJ-45F). The number of this NRC COM port determines the channel

number of that receiver.

• Connect the audio cable from the AUDIO OUT/AUX port on the receiver to the

corresponding RCVR port on the NRC. Be sure to select the RCVR port with the same

number as the COM port chosen in the previous step.

TEN-TEC RX-331

• The RX-331 must be configured to operate and communicate with the NRC units. This is

achieved by configuring the RX-331 DIP switches S1 and S2

10, 8

to:

o set the receiver address to 1

set rocker switches 1-8 of DIP switch S2 to 0,0,0,0,0,0,0,1 respectively

o set the serial communications to 19,200 bps, , 8 data bits, no parity, and 1 stop bit.

set rocker switches 1-8 of DIP switch S1 to 0,1,1,1,1,0,0,0 respectively.

• Once the receiver switch settings have been adjusted, cycle the receiver power for switch

settings to become active.

• Be sure to use the correct control and audio cables for the TEN-TEC RX-331.

11, 12

• Connect the D25M end of the combined NULL modem/control cable to the RS232, J1

port (D25F) on the receiver and the other end to one of the NRC’s COM ports (RJ-45F).

The number of this NRC COM port determines the channel number of that receiver.

• Connect the audio cable from the J8 port on the receiver to the corresponding RCVR port

on the NRC. Be sure to select the RCVR port with the same number as the COM port

chosen in the previous step.
