Install a 1756 ControlNet Communication Module
The USB port on ControlNet modules uses a Type B receptacle. The port is
USB 1.1-compatible and runs at 12 Mbps.
See
Table 7 - RSLinx Software Versions on page 47
for more information about
using the correct version of RSLinx software.
Use a USB cable to connect your computer to the USB port. The connection lets
you download programs to controllers and configure other devices, which are
accessible by the module, directly from your computer.
For more information about setting up a USB port, see
.
IMPORTANT
Do not simultaneously upgrade the firmware for more than one module at a
time through a USB port. If you do, one or more of the updates may fail in the
middle of the upgrade.
