with the RS232 port enabled as a
method to connect to the UDL software.
NOTE: For this connection a special
cable (that is supplied by Pyronix) is
required, or it can be created according
to the diagram on the right.
NOTE: If the PC does not have a serial
port, you may require a standard RS-232
to USB converter.

casing and plug the RS-232 cable into
