Installing the Hardware 13
The RCS/4000 RJ-45 connector does not have a DSR input pin. On an RCS/4000, DSR is
always on. To emulate the DSR pin behavior on the RCS/3000, connect DTR, which is
typically always on when the port is open, to the DSR input. Alternatively, if the serial
device provides CTS hardware flow control and you are enabling DTR/DSR hardware flow
control, you can connect DSR (DB-9 pin 6) to CTS (DB-9 pin 8).
Starting the RCS/3000
When the RCS/3000 is powered up, it will run a self-test. The LEDs will flash to indicate
normal operation. The following LED colors and patterns will be displayed during normal
startup, if no errors are detected.
•
Status LED – yellow LED, blinking rapidly, during self-test. When the RCS/3000 has
finished the self-test and is running in normal operating mode, the LED will turn green,
blinking approximately 1 times per sec.
•
LAN/HUB LEDs – during the self-test, the LED for the LAN and HUB will cycle
through:
1. off
2. red
3. yellow
When the self-test completes, the LEDs will be either yellow or green. Yellow means the
port is not connected; green means the port is connected to an active ethernet network.
The green LED will blink to show network activity.
•
Serial port LEDs – during the self-test, the LED for each serial port will cycle through:
1. off
2. green
3. red
4. yellow
When the self-test completes, the LEDs will be either yellow or green. Solid yellow
indicates a port that is not in use. Green indicates a port that is in use. The green LED
will blink when data is transmitted or received. It will blink 5 times per second when
data is continuously transmitted or received.
If any of the LEDs turn red, an error condition was detected. A serial port LED will turn red
for one blink, then return to green, if a parity, framing, or overrun error is encountered. Also,
a blinking red/yellow or blinking green/yellow indicator on the status LED signals an error.
