FUNCTION

The Computer Interface Module, model UMC, is used to

exchange digital commands between a PC (personal computer)

or server/gateway and UPB (Universal Powerline Bus) devices in

the home. The module communicates these commands over the

AC power wiring. The following model is available:

UMC-DB9: Serial RS-232 interface, DB9 connector

UPB devices can be freely located anywhere in the home. No

additional wiring is required and no radio frequency signals are

used.

INSTALLATION

The Computer Interface Module is designed for indoor use.

1. Plug the Computer Interface Module into a 120-volt outlet

near the computer or server (see illustration).

2. Connect the supplied interface cable to the socket on the

bottom of the module. Connect the other end of this cable to

the appropriate data port on the computer or controller.

3. If desired, any electrical device can be plugged into the

socket on the front of the module, which is always powered.

OPERATION

The Computer Interface Module exchanges UPB messages

between the powerline and the connected computer or controller.

The indicator on the module will glow AMBER when powered and

flash RED during messaging.

The interface has two operating modes: MESSAGE mode and

PULSE mode. The last-used operational mode is retained during

power interruption. UPStart software automatically sets the

interface to PULSE mode operation, but most controllers require

MESSAGE mode. To restore MESSAGE mode operation…

1. Place the UMC in SETUP mode by pressing the Program

Switch (located just above the indicator) five times rapidly

using a non-metallic toothpick. The indicator will

continuously blink RED.

2. Reset to MESSAGE mode by pressing the Program Switch

ten times. The indicator will continuously blink GREEN.

3. Press the Program Switch twice to exit SETUP mode.

CAUTION: Do not insert metal objects into the module

while it is connected to power.
