Step 4 — Remote connections
a. Contact closure connectors —
Connect an Extron
MMX 32 AAP or MMX 32 MAAP contact closure
remote control panel to these two 5-pole captive
screw connectors to provide control for outputs
1 and 2. Connect the 5 V and Gnd (-) 2-pole captive
screw connector on the AAP or MAAP to either of
these connectors.
b. RS-232 connector —
Connect an RS-232 control module to this 3-pole captive screw
connector (see image above) to allow remote control using the Extron Simple Instruction
Set
™
(SIS
™
) or the Extron Universal Switcher Control Program.
N
For full SIS commands and details of the Universal Switcher Control Program, refer to the
MMX 32 VGA MTP Users’s Guide.
Step 5 — Power
Plug the included external 12 VDC power supply into the 2-pole
captive screw connector. Wire the connector as shown at right.
