Make Network Connections
You can make these connections to a CompactLogix 5370 L2 controller:
• Make a USB Connection

Make a USB Connection
The controller has a USB port that uses a Type B receptacle. The port is USB 2.0-compatible and
operates at 12 Mbps.
Use a USB cable to connect your computer to the USB port. With this connection, you can
upgrade firmware and download programs to the controller directly from your computer.
1. Plug the USB cable into your CompactLogix 5370 L2 controller.
2. Plug the USB cable into your
computer.
IMPORTANT You must use RSLinx Classic software, version 3.51.00 or later, with your CompactLogix 5370 L2 controllers. With this
software version, there is no need to install an RSLinx Classic software driver. The driver appears automatically in the
software when a USB cable is connected to the controller and the computer.
ATTENTION: The USB port is intended for temporary local programming purposes only and not intended for
permanent connection.
The USB cable is not to exceed 3.0 m (9.84 ft) and must not contain hubs.
WARNING: Do not use the USB port in hazardous locations.
