Like Dominion KSX, many newer devices also provide serial ports in RJ45 form. However, as noted above, each 
implementation is proprietary: not all serial ports using RJ45 connectors are alike! 
Owners of hardware with RJ45 serial ports, who very familiar with network cabling, may be able to crimp their own 
UTP/Cat 5 cable such that no adapters are necessary to connect their device to Dominion KSX; a single, custom-
made UTP/Cat 5 cable can connect the device’s RJ45 serial port to Dominion KSX’s RJ45 serial device ports. 
To do so, reference the RJ45 pin-out diagram above, along with the serial RJ45 pin-out diagram of your device.  
 

For your convenience, Raritan also provides P/N CRLVR-15, a custom Cat5 cable that enables most Sun / Cisco 
RJ45 serial ports to be connected directly to Dominion KSX serial ports.  Alternatively, you may crimp this cable 
yourself by following the cable pin-out diagram below:

WARNING! Not all Sun and Cisco devices have been tested with this cable; you must refer to the user’s 
manual of your device and confirm its pin-out to ensure compatibility. If you are at all unfamiliar with this 
procedure, you should not attempt to make your own direct-connect cable – instead, use Raritan’s standard 
DB9 and DB25 adapters.
