Mapping Cables through a Splitter
The WireMaster Coax will map individual Remotes through a fully power passive split-
ter. Most splitters, like those used in CATV (Cable Television) are not power passive.
Some splitters are not power passive through all of their ports (partially passive). Sat-
ellite splitters and high quality splitters are often power passive, but not necessarily
through all of the ports.
For distribution systems using fully power passive splitters, the WireMaster Coax will
map individual Remotes through the splitters. Only one Remote at a time can be mapped.
Connecting more than one Remote at a time to the system will cause an incorrect ID on
the WireMaster Coax. Some equipment connected to the outputs of the splitters may
cause the WireMaster Coax to produce an incorrect ID. If in doubt, disconnect the
equipment.
Most consumer satellite distribution systems which use splitters are equipped with F
connectors, so several BNC to F adaptors are needed. Since only one Remote can be
mapped at a time, only two adaptors are needed . . . one for the chosen Remote, and
one for the WireMaster Coax.
Splitters are bi-directional . . . meaning that signals pass through them in both direc-
tions. Because of this behavior, the Remote can be connected to any port on the splitter,
and it can be “seen” on any other port.
A typical test would be to connect the chosen Remote to the input of the system, and
test at each outlet with the WireMaster Coax for the presence of the Remote’s ID. If the
correct ID is displayed, the system’s input is connected to the tested outlet. If OPEN or
SHORT is displayed, there may be no connection to the Remote, power passive split-
ters are not being used, or equipment connected to the splitters is interfering with the
ID.
Note: The WireMaster Coax will not test through active devices (amplifiers, switches,
modulators, etc.) or DC Blocks, Matching Transformers, or any other device that will
not pass the DC test signal or alters the characteristics of the signal.
