1 Overview
Antaira Technologies’ USB-C to RJ45 Console Cable connects from a computer USB port to the RJ45 console port of a
networking switch. This cable connects a computer with Windows or macOS to a Antaira serial console port for
configuration and management. The integrated FTDI chipset handles the USB signaling and protocol functions including
an RS-232 level shifter. FTDI drivers are available for download.
2 Installation Checklist
- Computer with an available USB-C port (USB 3.0) supporting data transfer
- Administrator permission on the computer to install the FTDI drivers
- Internet access to download the drivers
- Windows users may need to identify the 32-bit or 64-bit system type to install the correct drivers (System Control
Panel > System)
- Verify that the equipment console port is wired according to the Cisco standard. Below is the pinout of this rollover
cable that reverses the pins of the console port:

3 Quick Connect Notes
FTDI drivers should automatically install when connected to a computer with Windows 10.
1. Plug the USB end of the cable into an available USB port on the computer.
2. Identify the connected COM port assigned by the computer.
3. Open a terminal window with a Command Line Interface (CLI) terminal utility or terminal emulation software such
as PuTTY).
4. Plug the RJ45 end of the cable into the console port and turn on the equipment.
5. Set the bps, data bits, parity, stop bits and flow control settings required by the equipment.
(Typical Antaira settings are bps=115200 / data bits=8 / parity=none I stop bit=1 / flow control=none)

7 Troubleshooting Notes
●This is a custom Antaira cable that is designed to be used on Antaira managed switches to connect from a computer
to a switch. It is NOT a crossover cable that reverses TX and RX to connect two computers.
●Check that the RJ45 is connected to the console Port, not an aux or an Ethernet port. Only 1 console port can be
connected at a time.
●Disconnect any network or internet access as a test.
●If you are unsure of the assigned COM port:
1. Connect the cable to a USB port
2. Open the Device Manager in Windows or the USB Device Tree in macOS
3. Unplug the cable and note which entry disappears
●Connecting with a long USB extension cable may cause the console functions to operate incorrectly. A maximum
length of 15 feet is recommended.
●Older FTDI or Prolific drivers may need to be uninstalled in order to install the latest FTDI drivers. Uninstall the drivers,
plug-in the cable, and reinstall the drivers.(Consult the FTDI Driver Installation Guides on the CD for detailed
instructions).
