3 Operation

There isn’t much to operating an

IQ-RPT

. Just plug it in

and it works. The operating environment should be free

of salt and moisture with temperatures between 32° and

158° farenheit (0° to 70° celsius).

To help with troubleshooting, the Repeater provides

several indicators that are described next.

Power:Power:

Power: This amber front panel LED lights to show that

the unit is receiving AC power.

Input Status:Input Status:

Input Status: This green front panel LED flashes when

incoming data is received.

Output Status:Output Status:

Output Status: This yellow front panel LED flashes when

outgoing data is sent. It does not indicate the status of

the output cabling.

Output Continuity:Output Continuity:

Output Continuity: This red back panel LED lights when

there is a connection between the output of the Repeater

and the input of the next device on the Crown Bus. It

will not light unless current can flow in the Crown Bus

output circuit from the positive (+) output line back to

the negative (-) output line. (The negative output line is

effectively a return line to ground.) The LED will not light

if the output circuit is open, but it will light if the positive

and negative output lines are shorted.
