3.6. Port Control Operation
RS-232/USB Control
The HDMI 4x4 Matrix Switch features built-in firmware
that allows commands from an ASCII terminal to be
sent directly to the device via either a USB or RS-232
connection (not both simultaneously). If connecting with
an RS-232 cable, ensure that the cable has the straight-
through configuration shown in Figure 6.
Figure 6: RS-232 Cable Configuration
Port Control is performed with either the MuxLab
Control Center software, described in Section 3.7, or
with a terminal emulator such as the one available under
Windows with the ASCII Command Set described in
Appendix A. Please note that USB to RS-232 converter
cables could result in problems, depending on the
quality of the product.
