Digital I/O (digital input/output)
Congure each port as as a digital input or output,
with or without +5 VDC pull-up.
Use these ports to:
• Monitor or trigger events and functions (toggle relays,
issue commands, send e-mail), once congured.
• Power LEDs, incandescent lights, or other devices
that accept a TTL signal.
Flex I/O (digital input/output or analog input)
Congure each port as an analog input or as a digital
input or output with or without +5 VDC pull-up.

Reference voltage input (from amplier) – This allows the IPCP Pro to detect when the amp is present.
Control voltage (variable output to amp from IPCP Pro) – This signal controls the amp volume.
Control voltage output:

Volume Control
This port can be used to control the volume and mute or
unmute the audio for Extron half rack width audio ampliers.
• Connect to an Extron audio ampier to permit volume
control via touchpanel controls, macros, or schedules.
• Do not exceed 10 VDC input voltage.
Congure the maximum and minimum voltage limits. Set
Soft Start mode off or on (default) . Soft Start mode allows
volume to gradually increase from mute to the previous level
after muting or power-on to prevent loud audio bursts

NOTE: Use shielded cable and
place the control processor
as close as possible to the
amplier to avoid picking up
background noise via the
cable. Ideal cable length is
six feet or less.
NOTE: When audio mute is active, the
control processor sets output voltage
to
0 VDC, even if the voltage range
(minimum and maximum voltage
limits) has been set to levels above
zero, such as 2 V to 8 V.
