DC Volume control port (Vol/Mute) — This port connects an Extron
external volume control module, such as a VCM, or the MLC 52 VC
to the PVS 204SA. The range is 0 to 10 V, where 0 V is mute and 10 V
is maximum volume. When connected, the external volume control
module is the sole volume controller.
N Do not control the PVS volume via RS-232 if this port is connected to
a VCM 100, a VC 50, or an MLC 52 VC. If a VCM is controlling the volume,
an MLC should not be connected to the MLC/IR/RS-232 port.
Connect the supplied, male, 3-pole captive screw connector to this port,
wiring the connector as shown in figures 2-13 and 2-14.
