Serial communication

Flex I/O ports — Four I/O ports permit connection of
switches and sensors to provide input to the system, and
contact closure activation of relays for power, screen, or
projector lift control (output). Plug a serial cable into this
3.5 mm, 5-pole captive screw connector for flexible I/O
connection.
4
COM ports — Plug a 3.5 mm, 5-pole captive screw
connector into this socket for serial ports 1 and 2.
5
COM1 and COM2— Plug a serial cable into this 9-pin D
connector for serial port 1 or serial port 2 connection. See
figure 2-8 for pin assignments.
Take note that the IPL T SF24 allows for use of either the
9-pin D connector or the captive screw connector on
COM1 or COM2. The COM 9-pin D and the COM
captive screws cannot be loaded simultaneously.
6
IR/Serial out ports — Plug a serial cable into this 3.5 mm,
5-pole captive screw connector for infrared or serial
connections.
The IPL T SF24 and SFI244 interfaces can be used to control
display devices, switchers, and other A/V equipment via an
RS-232 connection. Factory default protocol for the control
interface is RS-232, 9600 baud, no parity, 8 data bits, 1 stop bit,
pacing = 0ms, and handshaking = off. The control device (PC,
laptop, etc.) can use either Extron’s Simple Instruction SetTM
(SISTM) or the graphical control program for Windows®, via a Web
browser.
Pin assignments for the rear panel, 9-pin D connector COM
ports on the IPL T SF24 are shown in figure 2-8.

Figure 2-6 — Power connector wiring
Do not tin the stripped power supply leads before installing
the captive screw connector. Tinned wires are not as secure in
the captive screw connectors and could pull out.
The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before continuing.
To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.

LAN Activity LED — A blinking yellow LED indicates
LAN activity.
LAN connector — Plug an RJ-45 jack into this socket to
connect the unit to a computer network. Use a straight-
through cable to connect to a switch, hub, or router, and a
crossover cable to connect directly to a PC.
