Termination and Mute Jumpering —

MTP 15HD Systems Only

The position of jumpers J3, J4, and J9 have no effect when the DA is installed as a part of an MTP CV series, MTP SV series, or VTT001/VTR001 system.

When an MTP T 15HD A or SW MTP T A provides the input, the MTP DA’s output can include analog audio in addition to the RGB video. When an MTP T 15HD RS provides the input, the DA output can include a serial (R-232) link in addition to the RGB video.

There are two sets of jumpers inside the MTP DA that set the DA to properly terminate the audio or serial portion of the input signal when the input signal was transmitted by an MTP 15HD A series (audio), SW MTP T (audio), or MTP 15HD RS series (serial) transmitter.

There is one jumper block that sets the DA to mute the audio or serial link when its video mute function is activated, or to always pass the audio or serial link regardless of the contact closure mute status.

By default, the MTP DA is configured with the internal jumpers set to terminate audio. For serial data applications, the DA can be configured to properly terminate that signal as follows:

1.	If applicable, disconnect all cables, remove the DA from its
	installation location, and remove any mounting brackets
	installed.
2.	Remove the two screws from either side of the DA and the
	two screws on the top (six screws total) and lift the top
	cover off of the DA (figure 2).

3. Select audio or serial distribution — Locate jumpers J3 and J4 on the main board and shift the jumper from the audio (A) (rear) to the serial (S) (front) position (figure 2).
