Termination and Mute Jumpering —
MTP 15HD Systems Only
N
The position of jumpers J3 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.
A jumper block 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.
A second jumper block 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 jumper J3 on
the main board and shift the jumper from the audio (A)
(rear) to the serial (S) (front) position (figure 2).
Remove 6 screws,
lift top straight up.

4. Enable or disable audio or serial distribution mute — If
desired, locate jumper J9 on the main board and shift the
jumper from the disable mute (S) (front) to the enable mute
(A) (rear) position (figure 2).
N
When J9 is set to the disable mute (S) (front) position,
the video mute has no effect on the DA’s audio or serial
distribution.
When J9 is set to the enable mute (A) (rear) position, the
DA mutes the audio or serial output when its contact
closure video mute is activated.
