Be sure that power is removed or the area is nonhazardous before proceeding.
Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create electrical
resistance that can affect module operation.
Configure RSLinx Software to Use the USB Port
The ControlNet interface module has a USB device port that uses a
Type B receptacle. The port is USB 1.1-compatible and runs at
12 Mbps. To use the USB port, you must have RSLinx software,
version 2.51 or later, installed on your workstation. Use a USB cable
to connect your workstation to the USB port. With this connection,
you can download programs to controllers and configure other
devices, which are accessible by the module, directly from your
workstation.
The USB cable is not to exceed 3.0 m (9.84 ft) and must not contain
hubs.
The USB port is intended for temporary local-programming purposes
only and not intended for permanent connection. If you connect or
disconnect the USB cable with power applied to this module or any
device on the USB network, an electrical arc can occur. This could
cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before
proceeding.
The 1756-CN2 and 1756-CN2R modules, series B, have an industrial
Type B USB port. The port has the same electrical characteristics as
other Type B ports, but a higher cable pull-out rating. For typical
applications in nonhazardous environments, you may use any
high-quality USB cable. If used in a hazardous location, a Samtec Inc.
RSP-119350 USB cable is required to meet the 15-Newton pull test
for hazardous environments.
