Connecting the WTI RJ-45 serial port to a Cisco device

To connect the WTI (CPM/DSM) device to the Cisco RJ-45 management port you will need to follow the steps listed below:


  • CISCO devices do not normally provide handshake, in order to talk the CISCO device handshake must be set to none on the port the CISCO device is connected to.
    • Issue a "/p #" where # is the port the CISCO device is connected to.
    • Under the communication settings set handshake to None
    • Port mode should reflect passive. This will keep it from triggering your Audit log with false attempts.

Port settings for CISCO device


  • Because the WTI device is pinned out like a CISCO you must have a Rollover cable between the WTI and CISCO device.
  • After saving your changes you should now be able to connect to your CISCO device.
  • Issue a "/C #" where # is the port the CISCO device is connected to.

* Some newer Cisco devices will require that DTR output be set to high. You can set the DTR setting under the port parameters.
