All of P&Bs intelligent relays are equipped with a front mounting mini USB port, this makes connection to laptop or pc very simply by using a standard usb to mini usb cable.
A driver can be downloaded from the website and installed in order to connect a programming device to a relay.

Some of the older relays use a RS232 port, P&B can provide a USB to RS232 cable complete with cross over connector which will allow you to connect from you USB port of your programming device to the RS232 relay front port directly.

In addition connection can be made to the RS485 port at the rear of the relay (if equipped) a convertor can be provided to allow the mini usb cable to be utilised via a convertor to the rear RS485 connection, the downloadable driver is still required in this case.
