Br-SDC LEDs, Switches and Connections:

There are only a small number of LEDs, connections and single conﬁguration switch

on each Br-SDC.

Status LEDs:

On the Br-SDC/09, Br-SDC/422:

1) Green ʻHeartʼ LED. This is used so you can see that the Br-SDC is alive. If this

LED doesnʼt ﬂash at least once per second, you should power down the Br-SDC

and check the power supply and connections to the Br-SDC. When in conﬁgura-

tion mode, the Br-SDCʼs ʻheartʼ LED will ﬂash at a far faster rate than normal.

2) Red LED attached to the serial data input line on the Br-SDC. Any time the Br-

SDC receives something through its serial port, you will see this LED ﬂash.

3) Yellow LED attached to the serial data transmission line on the Br-SDC. Any time

the Br-SDC sends out something through its serial port, you will see this LED

ﬂash.

On the Br-SDC8:

1) Yellow ʻHeartʼ LED. This is used so you can see that the Br-SDC8 is alive. If this

LED doesnʼt ﬂash at least once per second, you should power down the Br-SDC8

and check the power supply and connections to the Br-SDC.When in conﬁgura-

tion mode, the Br-SDCʼs ʻheartʼ LED will ﬂash at a far faster than the normal

ʻRunningʼ rate.

2) Green LED attached to the serial data input on the Br-SDC8ʼs ʻConﬁg./Mux. RS-

232 portʼ (female DE-09) or ʻMux./RS-422ʼ (female Rj-12) ports. Any time the Br-

SDC8 receives something through this serial port, you will see this LED ﬂash. You

will see this during conﬁguration, or when operating in any of the multiplexer

modes.

3) Red LED attached to the serial data output on the Br-SDC8ʼs ʻConﬁg./Mux. RS-

232 portʼ (female DE-09) or ʻMux./RS-422ʼ (female Rj-12) ports. Any time the Br-

SDC8 sends something out through this serial port, you will see this LED ﬂash.

You will see this during conﬁguration, or when operating in any of the multiplexer

modes, when serial data received through one of the multiplexed serial ports 1-8

(male DE-09) is routed to the Br-SDC8ʼs ʻConﬁg./Mux. RS-232 portʼ (female DE-

09) or ʻMux./RS-422ʼ (female Rj-12) ports.

4) Green LED attached to the serial data output on the Br-SDC8ʼs multiplexed serial

ports 1-8 (male DE-09). Any time the Br-SDC8 sends out something through one
