RJ-45 Pin Out

Connection to a PC

Note that many modern laptops do not come equipped with a DB9 style serial port. If your computer only has a USB style serial port, you'll need to obtain a USB to DB9 Serial port adapter cable.

B&K offers a pre-made connector suitable for connecting a serial port to a standard network CAT5 cable with RJ45 connectors (p/n 13290). However, should you wish to make your own, here is the pin configuration for a RJ45:

Plug one end of a RJ-45 terminated CAT5 cable into the serial communications port on the back of the computer using the serial DB9 to RJ-45 Adapter.

USB to Serial Adapter

USB to serial Adapters can be a convenient solution for connecting to a computer with no available DB9 style serial ports. Install the required drivers and then verify what com port the USB Adapter is on. Once your COM settings are determined, configure the BKcSuite and B&K CK1.2 / SR10.1 Editors for simple and easy setup.
