MuxLab’s HDMI 4x8 Matrix Switch, HDBT PoE may be controlled in any one of two
ways:
1. RS-232 Control
2. USB CDC Control
1. RS-232 Control
The HDMI 4x8 Matrix Switch, HDBT PoE features built-in firmware that allows
commands from an ASCII terminal to be sent directly to the device via an RS-232
connection. Ensure that the RS-232 cable has the straight-through configuration shown
in Figure 13.

Please note that the use of USB to RS232 converter cables may result in problems,
depending on the quality of the converters.
2. USB CDC Control
Commands from an ASCII terminal may also be sent directly to the device via a USB
connection. Maintenance can be performed with a terminal emulator, such as the one
available under windows with the ASCII Command set described in the Appendix of
this manual.
