specifications before connecting the
product to the power source.
This card provides quick start instructions for an experienced installer to set up and operate any of the MTP VGA video and RS‑232 transmission
systems.
Pre-installation — RS-232 Jumper
The receiver’s RS‑232 circuits are factory‑set to be one‑way, transmitter to receiver. If the system has only one
receiver, jumper JMP 1 on the main board can be set for two‑way communication as shown at right.
Installation
Step 1 — Mounting
Turn off or disconnect all equipment power sources and mount the MTP transmitter and up to eight receivers
as required.
Step 2 — Transmitter Inputs
• Connect a computer (VGA) video source to the Input connector.
• Connect a VGA monitor to the Monitor connector.
• Plug an RS‑232 device into the RS‑232 port. Wire the connector as shown below.

Step 3 — TP Cables Between Units
• Terminate a TP cable as shown at right. Connect it between the transmitter’s Output port and the
receiver’s Input port (both ends must match).
NOTE: If the unit is labeled “C7,” only CAT 7 cable should be used.
• For daisy-chaining, connect up to eight TP cables between a receiver’s Buffered
Output port and a daisy‑chained receiver’s Input port.
Step 4 — Receiver Outputs
• Connect a VGA monitor to the Output connector.
• Plug an RS‑232 device into the RS‑232 port. Wire the connector as shown in step 2, above.

Wire the 2‑pole captive screw connectors for the included external 12 VDC power supplies (see image a
on the right). Plug them into all units.
Grounding guidelines
Extron MTP 15HD RS products can be adversely affected by electrostatic discharge (ESD) if they are
not grounded correctly.
To prevent malfunctions or product damage, an experienced installer can correctly ground an
Extron MTP 15HD RS product in either of two ways:
• Ground the power input port — Insert one end of the grounding wire to the negative or ground
pin on the power input connector (see image a on the right). Tie the other end of the wire to an
earth ground.
• Ground the chassis — Use a connector hex nut as shown in image b on the right. Tie the other
end of the wire to an earth ground.
If you have any questions about how to ground a product in a specic application, contact an Extron technical
support specialist.
Step 7 — Pre-Peak, Peaking, and Level
• Transmitter Pre-Peak switch — View the image and set the Pre‑Peaking switch for the best image
quality to correct for long cable runs of the entire system (including all daisy‑chained receivers).
• Receiver Peaking control — View the image and adjust the Peaking control for the best image. Minimum setting
(full counterclockwise) is zero peaking.
• Receiver Level control — View the image and adjust the Level control for the best
brightness level.
Step 8 — Skew Compensation (SEQ Receivers)
Pair skew can be measured with test equipment or by viewing a crosshatch test pattern. The SEQ receivers have built‑in
skew compensation capabilities. Adjust the equalization as follows:
A. Zero the skew delay for red, green, and blue by using a small screwdriver to press and hold the Select button for
3 seconds. When the Red, Green, and Blue LEDs all go out, release the Select button.
B. Use UTP cable test equipment or examine the displayed image to determine which video signal (red, green or blue)
is shifted furthest to the right.
C. Select the furthest left video signal by using a small screwdriver to press and release the Select button until the LED
for the left‑shifted color (Red, Green, or Blue) lights.
D. Slowly rotate the Adjust control clockwise until the selected color is properly converged.
E. If the remaining colors are left shifted, repeat steps C and D.
