VTM-2000 Installation and Operation Handbook

C-3

9. The VTM-2000 polls the selected RCU-2000 every five seconds. If the VTM-2000

instrument fails to receive the poll after 60 seconds, the RCU-2000 assumes that a

communication break has occurred.

The LEDs flashing indicates a communication break. When communication is

once again established, the LEDs will reflect the current setting.

Operating the RCU-2000

Operating the RCU-2000 is the same as operating a VTM-2000 instrument with one

exception: selecting a VTM-2000 instrument for communication.

To select a VTM-2000 instrument for communication:

1. Press and hold the SETUP and EXIT buttons simultaneously to enable the selection

mode. The Phase LEDs flashes.

2. Rotate the CURVED ARROW knob to search for a Unit ID. Rotating clockwise

scans UP through the UNIT IDs. Rotating counterclockwise scans down through

the unit IDs.
