power and data are reaching the dome

Figure 5).

a. The green ac power LED (CR9) glows

steadily when ac power is applied.

b. For Manchester or SensorNet: The yellow

comm. LED (CR11) glows steadily

(Manchester) or blinks (SensorNet). If this

LED is off, then probably one or both

communication wires are open or both are

shorted together.

For RS-422: Press and hold data test switch

SW1 and observe nearby red (CR12) and

green (CR13) LEDs; they indicate the

following:

Constant green,

Blinking red

RS-422 line correctly wired.

Constant green,

RS-422 "Data In –" shorted to

ac ground.

Constant red,

Blinking green

"Data In +/ –" wires reversed.

Blinking red,

Reattaching the I/O Board

The following procedure refers to Figure 6:

1. If the wiring is OK, then pull the excess cable up

through the access hole.

2. Reinsert the I/O board.

Insert the board under the retaining fingers. The

board is keyed; it only fits into the base one

way. Press on the board to snap it into place.

3. Gently remove the dust cover.

Remove the cover from the 32-pin connector

and inspect the spring finger contacts. For

reliable connections, all contacts should be at

least 2mm above the surface of the connector.

CAUTION: Keep the dust cover for

use should you have to ship the base

and I/O board back to the

manufacturer.
