Projector control (Proj Cont) RS-232 port (-5 VDC to +5 VDC) — Connect a
1
cable between the projector/display and the left three poles of this 3.5 mm
captive screw connector for RS-232 one- or two-way control. Commands
from a downloaded projector/display driver or user-defined command
strings entered via the configuration program can be sent to the display
device from this port.
Connect a cable between the right three poles of the Proj Cont port and
accessories such as an Extron Power Sensor. The Power Sensor can be used
to let the switcher know when the projector is on or off. If these pins are not
connected to a Power Sensor, the SNS and ground pins can be used for digital
input as can pin 1 and ground of the 9-pin D RS-232 Host Control port.
Digital input: the power sense pin and the ground pin together act as a
digital input port (depending on configuration). This allows for an
additional way to trigger events or functions (such as triggering relays,
issuing commands, or sending an e-mail).
When configured as a digital input, this port will be in one of two states:
1 (on, high) or 2 (off, low). A closed circuit = a logic 1, an open circuit = a
logic 0. Threshold voltages are <0.6 VDC = low, >0.70 VDC = high.
Use the following illustrations as a wiring guide. Wiring varies depending
on the projector or display model. In most cases only the transmit (Tx) and

For bidirectional RS-232 communication, the transmit,
ground, and receive pins must be wired at both the
switcher and the projector/display.
