Connect RS232 Control
In addition to traditional RS232 control, the INT-66HDX 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 or DIGI-HDX-R for installations which require RS232 extension.
See page 21
for all available control commands for the INT-66HDX.
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 INT-66HDX
and the controller.
Discrete 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, such as the DIGI-HD60C-R or DIGI-HDX-R.
To use the RS232 extension capabilities of the INT-66HDX, 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.

Insert the removable three-pole terminal block into the RS232 tunneling port for the output zone which requires
remote RS232 control.
Remote RS232 Control via RS232 Routing
The INT-66HDX has the logic to pass RS232 commands to remote devices through the DE9 RS232 port. If the
remote display uses a baud rate other than 9600 baud, please use the RS232 tunneling option in order to receive
device status queries.

in an installation.
