RJ45 Serial Cables and Loopback Plugs
This section describe how to build your own null-modem or straight-through RJ45
serial cables. The following models have RJ45 connectors:
• RocketPort PCI: 4J (4-port RJ45), the Octacable model, and the Rack Mount
interface module
• RocketPort Universal PCI: Octacable model, the 4J (4-port RJ45) model
and the Rack Mount interface module. The ports on the 4J model are
numbered 0 to 3 and port 3 is the connector closest to the bus.
• RocketPort Plus Universal PCI: Octacable model.
Requirements There are no standards for the RJ45. Before you build the custom RJ45 serial
cable for your terminal equipment or device you should:
• Refer to the manufacturer’s installation guide if you need help with connector
pinouts or cables for the peripheral device.
• Supported RS-modes are described in the electronic document shipped with
your Comtrol device.
