About Using Multiple Cables
Once you have installed the device driver for a 1784-U2DHP cable, a unique
COM port will be created and associated with that module (for example,
COM9). If you connect a different 1784-U2DHP cable to the same computer, a
new COM port will be created and associated with the new cable
(for example, COM10).
Each time you connect a new 1784-U2DHP cable to the computer, refer to
step 10
on page 7 to determine the correct COM port for the additional cables.
When you are using multiple 1784-U2DHP cables on the same computer, you
must do one of these procedures.
Change the RSLinx Classic software driver settings to specify the
appropriate COM port for the connected cable.
Configure multiple RSLinx Classic software drivers.
