Installation Guide
AT-DISP-CTRL
The AT-DISP-CTRL provides both an
RS-232
and
IR
port, which can be used to send turn-on/
turn-off commands to the display, when a source is connected to the AT-DISP-CTRL. Command
configuration is handled through the web GUI. Refer to the User Manual for more information.
It is not necessary to connect both RS-232 and IR emitters to control the display. Either option
can be used, depending upon the environment and the system setup.
NOTE:
Typical DB9 connectors use pin 2 for TX, pin 3 for RX, and pin 5 for
ground. On some devices functions of pins 2 and 3 are reversed.
