AXB-TMC/TMX+ Television Managers
AXlink data and 12 VDC power supply connections
Use a 12 VDC power supply when the distance between the Central Controller and
AXB-TMC/TMX+ exceeds the limits described in the Wiring Guidelines table on page 7. Make
sure to connect only the GND wire on the AXlink connector when using a 12 VDC power supply,
as shown in FIG. 10.
Do not
connect the PWR wire to the AXlink connector's PWR (+) terminal.
DB9 data communication connector for a PC
The following table shows the front panel DB-9 Program port connector, pinouts, and signals.
Power Current Sensor Connections
The optional AMX Power Current Sensor (PCS) provides power sensing for equipment that does
not generate horizontal scan frequencies. Connect the optional PCS, as shown in FIG. 11, for
automated power control using Send_Commands PON and POF. A PIN command must be sent to
the AXB-TMC/TMX+ either from terminal mode or from within an Axcess program. If PIN is not
used, the PCS state is received as
[TM-Device, 251]
for I/O 1.
