MTP 15HD RS • Setup Guide (Continued)

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 installer can correctly ground an Extron MTP 15HD RS series product by grounding the power input port. Insert one end of the grounding wire to the negative or ground pin on the power input connector (see figure 5).

Tie the other end of the wire to and earth ground.

If you have any questions about how to ground a product in a specific application, contact an Extron technical support specialist.

7.Configure EDID.

See the EDID Minder section below for instructions on configuring EDID.

8.Adjust level and peaking.

•Pre-Peak switch (transmitter) — View the image and set the Pre-Peaking switch (E). Set this switch to On (up) to compensate for long cable runs of the entire system.

•Level control (receiver) — View the image and adjust the Level control (see figure 6). Full counterclockwise is minimum level.

•Peaking control (receiver) — View the image and adjust the Peaking control (see figure 6). Full counterclockwise is zero peaking.

9.Adjust skew delay control (SEQ receivers). Adjust the skew delay as follows (see figure 7):

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 turn off, 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 left.

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 lights.

d.Slowly rotate the Delay knob clockwise until the selected color is converged.

e.If the remaining colors are left shifted, repeat steps b through d.

EDID Minder

To use factory-installed EDID information or the user-recorded EDID:

1.If you have not already done so, connect the source device to the MTP 15HD transmitter. Do not power on the source device at this time.

2.Set the front panel DIP switch (C) to the required frequency (50 or 60 Hz).

3.Set the rotary dial (D) to the required position (see the table to the right). Positions 1 through E are factory installed. Position 0 is for user-recorded EDID information. Position F passes the EDID from the display connected to the Monitor loop-through port on the transmitter back to the input.

To record EDID information from a specific monitor:

1.Turn the EDID Select dial (D) to position 0.

NOTE: The frequency DIP switch position (C) has no effect in this mode.

2.Connect a display to the Monitor connector on the transmitter.

NOTE: The MTP 15HD RS transmitter should be supplying the necessary 5 VDC to power on the display. However, to ensure that EDID is being transmitted, power on the display.

3.Press and release the recessed Record button (B) to begin the recording process. The Record LED (A) will flash red rapidly during recording, then return to solid green after recording is completed. At this time, the display can be disconnected. Connect the source device to the input connector.

4.Power on or restart the source device.
