Typical MMX 32 VGA MTP / control panel application
Only one MMX 32 AAP or MMX 32 MAAP control panel can
be used to control each output.
Extron recommends shielded twisted pair cable, such as
STP 22 Dual Plenum cable, part #22-162-03 (or equivalent),
for the connection between the control panel and the switcher.
Unshielded cable can allow crosstalk and interference between the
MMX and the control panel.
Connecting the control panel to an MMX 32 VGA A
See the drawing below. The wire connected to the 5 VDC pole
(
4
on pages 2 and 3) should not be daisy chained. The power
for each AAP or MAAP must come directly from the Tally Power
connector on the MMX switcher.
See the drawing below. The wire connected to the Ground pole
(
5
on pages 2 and 3) should not be shared or jumpered between
two AAPs and/or MAAPs. Run a separate ground wire for each
AAP and/or MAAP. Use the drain wire of the cable for ground.
The drawing below shows a control panel wired to select the input
tied to MMX 32 VGA A output 2, using pins 7, 8, and 9 on the
Remote connector. To select the input tied to output 1, use pins 1,
4, and 6 on the Remote connector.
