Step 4 — Connect Outputs from MTP/HDMI U R
Digital video — Connect a display to the HDMI
connector for digital video output.
Analog video — Connect the analog outputs as
shown at right.
Audio — Connect a suitable audio device, such as
powered speakers, to the 5-pole captive screw audio
output connector for a balanced or unbalanced, dual
mono audio signal. Wire connector as shown at right.
NOTE: The audio signal is detected on the MTP input and then is distributed to the audio connector for output.
RS-232 control (digital side) — Connect a serial communications port on a display device to the
3.5 mm, 3-pole captive screw connector (labeled RS-232 pass-thru) for pass-through RS-232
bidirectional communication. Wire the connector as shown at right.
NOTE: The RS-232 control port on the analog side is not used in the MLS 608 D system.
Step 5 — Connect Control Devices
RS-232 control — Connect a host computer or control system (such
as an optional MLC 226) to the 5-pin connector (see m on page 1)
for MLS switcher configuration and control via RS-232 using
Extron software or Simple Instruction Set (SIS) commands.
Wire the MLS as shown at right.
NOTE: This serial port is independent of the front panel
configuration port. Both may be used for MLS control.
RS-232 protocol (default values):
• 38400 baud •1 stop bit • no parity • 8 data bits • no ow control
NOTE: The ‘+’ and ‘-’ pins on this connector can be used to
power a controller, for example an MLC 226 IP and a
connected IRCM-DV+.
RS-232 Insert port (optional) — Connect an optional control
device (for example an MLC 226 IP via the RS-232 display control port)
to the 5-pin connector (see n on page 1) for pass through RS-232
communication to a connected projector or display device.
Wire the connection as shown at right.
Step 6 — Connect Power
MLS 608 D — Plug in a standard IEC power cord from a 110 - 240 VAC, 50 - 60 Hz power
source into the receptacle (see
a
on page 1).
Optional — Connect the 2-pole power connector (see
e
on page 1)
for remote power to an
MTP transmitter or receiver. Wire the connection as shown at right.
Optional — Connect the “+” and ”-” pins on the RS-232 connector
(see
m
on page 1) for remote
power to an optional controller (such as the MLC 226). See second note, step 4 above.
MTP/HDMI U R — Connect the 2-pole 3.5 millimeter captive screw connector from the 12 VDC,
1.0 A external power supply (provided) to this receptacle on the rear panel, or connect to the 2-pole
power connector (see
e
on page 1) on the MLS 608 D. Wire connector as shown at right.
For both devices, when power is applied the front panel power LED lights.
