Key Label Description

TO MAIN UNIT 9-pin, D-sub, male connector connects to the REMOTE connector on the VTM-200

to provide RS-422 communication; the communication parameters are 8 data bits,

no parity, with the baud rate fixed at 38,400 bps.

5V DC IN Connects to the DC power plug on the RCU-200 DC power supply; a knurled ring

enables the power plug to be secured to the jack after the plug is fully inserted.

This connection must be made before AC power is supplied.

The RCU-200 permits operation of the VTM-200 or VTM-200L (VTM-200 with blank

front panel) from a remote location. It is a 19” rack-mounted unit powered by a small

external power supply and connected to the main unit by a 9-conductor cable (25 foot,

supplied) at a maximum of 80 feet (RS-232) or 1000 feet (RS-422). For configuration

from a RS-232 signal connection to a RS-422 signal connection see RCU-200 COM

Port Electrical Interface Selection on page D-2.

The RCU-200 front panel is identical to that of the VTM-200, and, with the exception

of one restriction, all buttons, knobs and indicators have the same functionality as on

the VTM-200 front panel. The restriction prevents the user from changing the data rate

of the communication between the remote panel and the main unit.

To install the RCU-200:

NOTE: Inspect the shipping container of the RCU-200 prior to installation, and report any external or

subsequent internal damage to the shipper.

1. Mount the RCU-200 with the enclosed rack mounting hardware.

2. Connect the DC power supply to the 5V DC IN on the back panel (secure it by

hand-tightening the knurled collar).

3. Connect the end of the communications cable with the 9-pin, female, “D”

connector to the 9-pin, male, “D” connector (marked TO MAIN UNIT) on the back
