Connect RS232 Control
In addition to traditional RS232 control, the FLX-44 has an advanced RS232 control mechanism which allows RS232
tunneling and routing through the HDBaseT output port to control remote devices. Intelix recommends using the
DIGI-HD60C-R for installations which require RS232 extension.
See page 27 for all available control commands for the FLX-44.
Matrix Control via RS232
Remote RS232 Control via Tunneling
The RS232 control port requires a standard straight-through serial cable for operation. The default settings for the
RS232 port are:
• 9600 baud
• 8 Data Bits
• 1 Stop Bit
• Parity = none
Connect a standard straight-through serial cable with DE9 connector
between the RS232 port on the FLX-44 and the controller.
Discrete remote control of remote display devices is possible by connecting an RS232 output of a control system
to the 3-pole terminal block on the output of the matrix. A compatible HDBaseT with control receiver is required
to pass the control signals to the display devices.
To use the RS232 extension capabilities of the FLX-44, connect the TX, ground, and RX control signal wires to the
removable 3-pole terminal block. Consult the manual of the control device(s) to determine which pins the TX/RX
signals are carried on. Be sure to always connect TX to RX and RX to TX.
