3.10. Port Control Operation
MuxLab’s 4x4 Matrix Switch, HDBT may be controlled in the following two ways:
1. RS-232 Control
2. USB CDC Control
1. RS-232 Control
The Matrix Switch 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 11.
Figure 11: RS-232 Cable Configuration
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.
