Termination And Mute Jumpering - Mtp 15Hd Systems Only - Extron electronics MTP DA4 User Manual

Termination and Mute Jumpering —
MTP 15HD Systems Only
NOTE:
When an MTP T 15HD A or SW MTP T 15HD A provides the input, the MTP DA output can
include analog audio as well as RGB video. When an MTP T 15HD RS provides the input, the
DA output can include a serial (RS-232) link as well as RGB video.
A jumper block inside the MTP DA sets the DA to properly terminate the audio or serial
portion of the input signal when the input signal is 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. The DA can also be set 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
(default). For serial data applications, the DA can be configured to properly terminate the
signal as follows:
1.

3.
The position of jumpers J3 and J9 have no effect when the DA is installed as a
part of an MTP SV series or VTT001/VTR001 system.
If applicable, disconnect all cables, remove the DA from its installation location, and
remove any mounting brackets installed (see
Remove the two screws from both sides of the DA and the two screws on the top (six
screws total) and lift the top cover off of the DA (see figure 2).
Select audio or serial distribution — Locate jumper J3 on the main board and
shift the jumper from the audio (default, on the right) to the serial (left) position (see
figure 2).
