B.2 RS-232
A DB9 female to DB9 male cable (such as Campbell Scientific part number
10873) is used to connect the NL240’s RS-232 port to the datalogger’s RS-232
port. The supplied SC12 cable can also be used. A DB9 female null modem
cable (such as Campbell Scientific part number 13657) is used to connect the
NL240’s RS-232 port to a PC’s RS-232 port. The RS-232 cable should be kept
short when using high baud rates.
