Detailed Operation

Identifying Cables (Mapping)

The WireMaster Coax will not work if AC or DC voltage is present. Some coaxial cables

have AC or DC voltage on them to operate amplifiers, preamplifiers, LNB’s, etc. The

OFF: OVERLOAD / VOLTAGE test position of the Function switch tests the connected

cable for the presence of AC or DC voltage.

The WireMaster Coax is intended for use on un-terminated cables . . . that is, cables

without any devices connected to them.

Before connecting any Remotes to cables, connect the WireMaster Coax, with its Func-

tion switch set to OFF: OVERLOAD / VOLTAGE, to each of the cables to be mapped. If

there is an AC or DC (plus) voltage present, the OVERLOAD / VOLTAGE indicator LED

will light and the warning beeper will sound intermittently. If this occurs, the cable(s)

cannot be Mapped / Identified (ID’ed) with the WireMaster Coax.

When it has been determined that no AC or DC voltage is present, connect the various

Remotes to the cables to be ID’ed

Press the UNLOCK button and set the Function switch to the CABLE MAP position. The

green BATTERY TEST LED must flash. The OPEN LED must light. If the OPEN LED does

not light, there may be a defect in the WireMaster Coax that will prevent it from cor-

rectly ID’ing a cable. Check or replace the battery before proceeding.

At the ends of the target cables opposite the Remotes, connect the WireMaster Coax,

in succession, to each cable, noting the ID number of the LED that lights.

If upon connecting the WireMaster Coax to a cable, the OPEN LED remains lit, the

cable may not have a Remote at its opposite end, an open fault may be present in the

cable, or a splitter may be present in the cable. The WireMaster Coax will not work

through splitters, amplifiers, or any other DC blocking devices.

If the SHORT / CONTINUITY LED lights and the beeper sounds, the cable may be shorted,

or some device is connected to the cable that appears as a short to the WireMaster

Coax.
