Appendix A – Creating a Virtual COM Port
The USB (mini-B) port on the DGX TX and RX modules can be used to create a virtual COM port on
the PC. Once a virtual COM port is created, the USB port acts the same as a standard serial connection.
The virtual COM ports on the modules can be used with the programs/utilities listed in the table below.
Establishing a Virtual COM Port
The use of USB hubs with DGX Fiber modules is not recommended. AMX recommends a direct USB
connection between a DGX Fiber module and the computer’s USB connector.
Important:
You must have adequate rights to install USB device drivers to the PC. Before
proceeding, check with your System Administrator to be sure you have the required access.
When establishing a new connection, complete all of the steps in the instructions starting below.
Or
When reconnecting after previously establishing a USB connection, complete Steps 1 and 2 below
and then set up and run the desired software program or utility (see the options in the table above).
To attach PC to USB port on TX or RX and establish a virtual COM port:
1.
Download the APBridge.inf file (Go to www.amx.com and enter APBridge in the Search
AMX.com field in the upper right-hand corner of the site). No user permissions are required for this
download.
2. Apply power to the module (see page 34).
3.
Using a USB mini-B cable (FG10-5965 provided) connect the module to a PC that is running
Windows (FIG. 41).*
New connection: Power LED blinks red rapidly until the process is completed successfully.
Previous connection: Power LED blinks red rapidly for a few seconds while connection is made.
* When the USB cable is inserted on an RX Module, the RX’s blower will toggle to either a high (full
on) or low (completely off) state and remain in that state until the USB cable is removed. Once the cable
is removed, the blower will return to its normal operational state.
