CTP2000 Series Console Cable Pinouts

CTP2008, CTP2024, and CTP2056 devices use an RJ-45 connected to the COM2 port. This cable must be connected during the first boot process. Use a shielded cable for the COM2 port on the CTP2056 device. Figure 1 displays the console cable pin configurations for CTP2000 series devices. On the left is the RJ-45 connector, and on the right is the DB-9 connector with the pin numbering indicated.

The console connections are configured to the following parameters:

  • Speed: 9600 bps
  • Data bits: 8
  • Stop bits: 1
  • Flow control: Xon/Xoff
  • Parity: none
