Still Doesn't Work!
Hooking up multiple listerners to one talker is really no different than doing
a 1-to-1 connection. Just keep in mind a few things:
-
There must only be one talker on a circuit.
-
Connect the talker's Transmit (+) wire and all of the listeners'
Receive (+) wires together.
-
Remember that the signal ground (Transmit(-), Receive (-)) wires of all of
the devices must be connected (if they have one) .
-
If a listener does not have a Receive (-) wire, it's power
ground must be on the same circuit as the power ground of the talker.
-
If the talker does not have a Transmit (-) wire ,
connect all of the listeners' Receive (-) to the same circuit
that the talker's negative (-) battery connection is on.
-
If the talker has a Transmit (-) wire, but none
of the listeners has a Receive (-) wire, just leave the talker's Transmit (-)
wire floating (disconnected).
-
You can simply crimpt all the wires together, but the easiest thing
to do is to use circuit blocks or bus bars as described earlier. By using
jumpers to connect multiple connections (see below), it is easy to connect
multiple listerners to a single talker. In addition, when one of the devices
breaks, you can easily remove its interface cable.
