Setting audio jumpers for use with unmodified receivers
N Older (unmodified) transmitters and receivers are fully compatible with each
other, but not with the TPX 88 A twisted pair matrix switcher.
Redesigned (modified) transmitters and receivers are fully compatible with each
other and with the TPX 88 A.
You can use jumper connections to make redesigned transmitters and receivers
compatible with the unmodified models, but not with the TPX 88 A.
N Redesigned (modified) transmitters and receivers have an identifying label.
The audio that is associated with the composite video link of TP T 15HD AV
transmitters is transmitted on wire pair 3 and 6. This configuration is compatible
with redesigned TP receivers and the TPX 88 A.
If you intend to match a TP T 15HD AV transmitter with an older, unmodified TP
receiver, and you do not plan to include a TPX 88 A in your system, you can set the
transmitter to send the audio on wire pair 7 and 8, making it compatible with an
older TP receiver, by shifting internal jumpers as follows:
1 . Remove the two screws on each side and the screw on top of the cover.

Configuring audio jumpers
2 . Slide the cover back until it clears the rear panel connectors, then lift it off.
3 . Locate jumpers J6 and J7 on the printed circuit board.
4 . Place the jumpers on the following pins as appropriate:
• For compatibility with redesigned (modified) receivers and the TPX 88 A,
place the jumpers so that they connect pin 1 to pin 2 at both jumper
locations.
• For compatibility with older (unmodified) receivers, place the jumper so
that they connect pin 2 to pin 3 at both jumper locations.
5 . Replace the cover and reinstall the screws.
