RS-232 SERIAL COMMUNICATIONS
What features are available via the RS-232 serial communications port?
The 8x4 Matrix for HDMI can accept commands through the RS-232 serial
communications port located on the rear panel. The current RS-232 control
features are:
• Switching/routing of inputs to outputs without the RMT-16IR remote control.
• Switch EDID management modes without opening the unit to physically
modify DIP switches.
• Change IR code channel without opening the unit to physically modify DIP
switches. (The IR code channel will still need to be manually modifi ed on the
RMT-16IR remote control to match the code channel.)
How do I use these features?
These features were initially intended for utilization by custom installers in
automated setups. However, these features can be tested by using any Windows
PC with the Hyperterminal program.
What pins are used for communication with the 8x4 Matrix for HDMI?
Only pins 2 (Receive), 3 (Transmit), and 5 (Ground) are used for communication.
A null-modem adapter should not be used with this product.
