Serial Communication
c
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 millimeter, 5-pole captive
screw connector for flexible I/O connection (see
Flex I/O Connection ).
d
COM ports — Plug a 3.5 millimeter, 5-pole captive screw connector into this socket
for serial ports 1 and 2.
Factory default protocol for the control interface is:
• RS-232 • 8 data bits • pacing = 0 milliseconds
• 9600 baud • 1 stop bit • handshaking = off
• no parity
e
IR ports — Plug an IR cable into this 3.5 millimeter, 8-pole captive screw connector
for infrared connections (see IR Connection ).
The IPL T SFI244 unit can be used to control display devices, switchers, and other A/V
equipment via an RS-232 connection.
