RS-232 output inserts
e
RS-232 Output Insert connectors — For bidirectional RS-232
data that is routed to a specific (unswitchable) TP output,
connect a serial device to one of the RS-232 Output Insert 3-pole
captive screw connectors.

Each RS-232 Output Insert must be enabled. See the
"RS-232 output inserts enables" SIS commands on
page 4-5.
N
The switch time for the RS-232 output insert is 50 ms.
Outputs
f
TP outputs — Connect up to 8, 16, or 32 (depending
on the matrix size) compatible MTP receivers to the
Outputs RJ-45 connectors.
g
Local RGB (VGA) outputs — Connect one or two
RGBHV video displays to the female Local
Outputs (VGA) 15-pin HD connectors.
N
Matrix sizes 1616 and smaller (excluding the
MTPX Plus 128) have one local video output.
Matrix sizes 1632 and larger and the MTPX Plus 128
have two local video outputs.
N
The Local outputs are always outputs 1 and 2.
N
The video that is output on these connectors is converted
from the tied proprietary TP input signal or the local
(VGA) input.
N
This connector can also output HD component video,
component video, S-video, or composite video if that is the
video format that was input.
If the video output is NTSC component video, S-video, or
composite video, set the output to no sync processing. See
the "Local video output sync polarity" SIS commands on
page 4-9.

Local audio outputs — Connect audio devices, such as audio
amplifiers or powered speakers to these two, four, or eight
3.5 mm, Mono Audio (local audio) Outputs 5-pole captive screw
connectors to receive unamplified, mono line level audio.

N
The MTPX Plus 128 has two local audio outputs.
Matrix sizes 1616 and smaller have four local audio
outputs.
Matrix sizes 1632 and larger have eight local audio
outputs.
N
These outputs are always outputs 1 and 2 (MTPX Plus 128),
outputs 1 through 4 (matrix sizes up to 1616) or outputs
1 through 8 (matrix sizes 1632 and larger), with the same
inputs tied to them as the TP output of the same number.
N
Each local output has a volume control. See "Viewing and
Adjusting the Audio Level" on page 3-7.

Remote port (switchers other than the MTPX Plus 128) — If
desired, connect a control system or computer to the rear panel
Remote RS-232/RS-422 port.
