Imprimir páginaINSTALLATION AND CONFIGURATION
The ASA468 Adapter has two terminal connection methods. A standard female
RJ45 jack is supplied on one end which can be attached to any audioShare
device by using an appropriate length of Cat 5 cable, terminated at both ends with
male RJ45 plugs using standard EIA/TIA568B wiring configuration. The other
end has an 8-position Phoenix-type screw terminal block where the non-standard
cable can be attached. Wires should be attached in twisted or shielded pairs. The
first pair between pins 1 and 2, the next pair between pins 3 and 4, etc. The
diagram below shows the pin configuration. Pins 1 and 2 of the terminal block are
for power, pins 3 and 4 are for the data bus, pins 5 and 6 are for Media Bus 2, and
pins 7 and 8 are for Media Bus 1.
Just behind the terminal block are two jumpers (See Figure 2). These jumpers
determine whether Media Bus 1 is transmitted over pins 7 and 8 (normal
operation) or over the power pair, pins 1 and 2.
The following table shows the various wiring and jumper configurations for 4, 6
and 8-wire cables.

When using 8 wires, the jumpers should be installed in position 1-2. For 6 or 4
wire cables, the jumpers should be installed in position 2-3.
Jumpers are changed by opening the protective cover (see Figure 1) and simply
grabbing the end of each jumper with a pair of needle-nose pliers and pulling them
off of the header, then sliding them back on in the proper position (see Figure 3).
After configuring the jumpers and installing the wires and a cable tie (if desired),
snap the protective cover back in place.
