Operating the RCU-200
Operating the RCU-200 is the same as operating a VTM-200.
Troubleshooting
Table D-3. RCU-200: Problems, Causes, and Solutions
Problem/Symptom Possible Cause Solution or Explanation
DC power supply cable is not properly
connected to back panel 5V DC IN
connector.
Properly connect the DC power
supply.
No LEDs are
illuminated.
DC power supply has no AC power
applied.
Apply AC power.
Cable from VTM-200(L) to RCU-200 is
defective or not properly connected.
Check the cable and the
connection.
VTM-200 is not powered up. Apply power to the VTM-200.
INPUT LEDs flash in
alternate pairs (e.g.,
A+D and B+C); no
other LEDs are
illuminated.
VTM-200 is not selected. Select a VTM-200.
If the problem still exists after troubleshooting the RCU-200, see Appendix B, “Service
Support,” for further instructions.
Specifications
Interface
COM
9-pin, male, D-connector (marked TO MAIN UNIT) on the back panel of the
RCU-200 provides the interface point for the cable connection to the
VTM-200. Interface levels are factory set for the EIA-232 electrical interface,
but can be configured to RS-422 electrical interface. This permits use of
cable lengths with a maximum of 50 feet (EIA-232) and 1000 feet (RS-422).
A 25-foot interface cable is normally provided.
Power Requirements
AC power source
115–230 VAC, 50/60 Hz. DC power is supplied to the 5 VDC IN jack on the
back of the RCU-200 via a short power cable from an external power supply
(provided).
Power consumption
Less than 30 VA
