Horizontal Sync switch (1) — Set this switch up
for positive horizontal sync (or positive composite
sync if the Composite Sync switch is on) or down
for negative sync.
Most devices use negative sync.
Vertical Sync switch (2) — Set this switch up for positive
vertical sync or down for negative sync.
Most devices use negative sync.
Composite Sync switch (3) — Set this switch up for RGBS or
down to output RGBHV or RGsB video. See the table below.

Sync-on-Green (SOG) switch (4) — Set this switch up for RGsB
video (when the input is RGBHV or RGBS) or down to output
RGBHV, RsGsBs, or RGBS video. See the table above.
Video switch (5) — Set this switch up for RsGsBs, RGsB,
component/S-video/composite video or down to output
RGBHV or RGBS video. See the table above.
Set the Composite Sync, SOG, and Video DIP switches
as shown in the table above for the various input and
output video formats.
End Unit switch (RL receiver only) (6) — Set this switch up if
either of the following is true:
• The receiver being configured is the only receiver
connected to the transmitter.
• The receiver being configured is the last receiver in a
daisy-chained system.

CAUTION Power supply voltage polarity is critical. Incorrect
voltage polarity can damage the power supply and
the MTP. Identify the power cord negative lead by
the ridges on the side of the cord (figure 11).
To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.
The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before wiring.
The length of the exposed (stripped) copper wires is
CAUTION
important. The ideal length is 3/16" (5 mm).
Longer bare wires can short together. Shorter wires
are not as secure in the direct insertion connectors
and could be pulled out.
Do not tin the power supply leads before installing them
in the direct insertion connector. Tinned wires are not as
secure in the connectors and could be pulled out.
Alternatively, an optional Extron PS 123 Universal 12 VDC
Power Supply, part #60-814-01, can power multiple Extron
12 VDC devices using only one AC power connector.
