The RCU-200 electrical interface can be configured for RS-422 via internal pin

jumpers for use with VTM-200(L) units having RS-422 interface capability. The

RCU-200 is factory-configured with an EIA-232 electrical interface. Connecting an

RCU-200 configured for RS-422 with a VTM-200(L) using an EIA-232 interface (or

vice versa) will result in erratic operation, or no operation, and, possibly, damage to

both units.

This coaxial jack mates with the DC power plug from the RCU-200 DC power supply.

A knurled ring allows the power plug to be secured to the jack once the plug has been

fully inserted. The plug should be connected to the RCU-200 before AC power is

supplied to the power supply.
