Contact Closure Control
The MMX 32 VGA MTP can be controlled remotely using the optional Extron MMX 32 AAP
contact closure control panel (part number 70-277-01, -11, or -21) or the MMX 32 MAAP
contact closure panel (part number 70-277-12 or -22). Each panel controls one output and
has three input selector buttons and LEDs.
The contact closure system uses the two 5-pole captive screw connectors, which control
outputs 1 and 2 separately. Each contact closure pin corresponds to an input/output
connection, or tie. A tie is made when one pin is momentarily connected to ground. Each
pin returns a signal to the remote control panel after a tie is made, lighting the control panel
LED corresponding to the selected input. A +5 V port is used when controlling the output
with an MMX 32 AAP/MAAP panel.
