3.2.1 Direct Connect from the NL100/105 to a Datalogger
Either the CS I/O port or the RS-232 port can be used to directly connect a
datalogger to the NL100/105. Cabling or additional peripherals are required as
listed below. Note that two dataloggers can be connected to one NL100/105 by
using combinations of the connections described below. Each port must be
assigned a unique port number.
NL100/105 CS I/O port to datalogger CS I/O port - An SC12 cable is
connected to the CS I/O ports on both devices. An SC12 is typically shipped
with all datalogger peripherals.
NL100/105 RS-232 port to datalogger RS-232 port - A standard 9 to 9 pin
communications cable should be connected to the RS-232 port on both devices.
NL100/105 RS-232 port to datalogger CS I/O port - A serial communications
cable should be connected to the RS-232 port of the NL100/105. This cable
should be connected to an SC32A or SC32B optically isolated interface, and
