NOTE: The receiver auto-detects whether the signal on the audio/RS-232 pair of the
TP input is audio or RS-232. It then converts the signal content accordingly,
and outputs the signals on the appropriate pins of this connector.

NOTE: The length of exposed wires is critical. The ideal length is 3/16 inch (5 mm).
If the stripped section of wire is longer than 3/16 inch, the exposed wires may
touch, causing a short circuit. If it is shorter than 3/16 inch, wires can be easily
pulled out of the captive screw connectors.
Figure 5 identifies the tip, ring, and sleeve parts of standard audio connectors. A mono
(RCA) audio connector consists of the tip and sleeve. A stereo audio connector consists of
the tip, ring and sleeve. The tip, ring, and sleeve wires are also shown on the captive screw
audio connector diagrams.

RJ-45 connector —
MTP T 15HD RSA board — Connect the transmitter
to a suitable MTP receiver via this connector. Terminate
the cable as shown at right, using the same standard
(A or B) at both ends
MTP R 15HD RSA SEQ board — Connect the twisted
pair cable from the transmitter to this input connector.
Terminate the cable using the same standard (A or B)
at both ends.
NOTE: If using Enhanced Skew-Free A/V cable, use the TIA T568A standard only.
CAUTION: Do not connect the twisted pair input cables to any devices LAN port, or
connect a LAN cable to the MTP ports.
d
Power LED — This LED lights green to indicate that power is applied to the board.
e
Pre-peaking toggle switch (MTP T 15HD RSA only) — This switch toggles pre-peaking
on or off. Pre-peaking boosts the transmission distance for long cable runs.
NOTE: The transmission distance varies greatly depending on the signal resolution
and on the type of cable, graphic card, and display used in the system.
