NL100/105 Network Link Interface
Power Supply Requirements
The NL100/105 is powered via the green G 12V connector (11 to 16
VDC at 140 mA average current) on the front panel of the unit.
Cable Specifications
The Ethernet 10 Base-T cable should be a Category 5 twisted pair cable.
Campbell Scientific recommends the 13658. The two active pairs in an
Ethernet 10 Base-T network are pins 1 & 2 and pins 3 & 6. Use only
dedicated wire pairs (such as blue/white & white/blue, orange/white &
white/orange) for the active pairs.
RJ-45 Pin-Outs: Pin 1 = TD+, Pin 2 = TD-, Pin 3 = RD+, Pin 6 = RD-
A DB9 female to DB9 male cable such as the 10873 is used to connect
the NL100’s RS-232 port to the datalogger’s RS-232 port. A DB9 female
null modem cable such as the 13657 is used to connect the NL100’s RS-
232 port to a PC’s RS-232 port. The RS-232 cable should be kept at
lengths of
≤ 6 feet to maintain high data throughput rates.
The CS I/O 9 Pin cable is a straight through cable with all 9 pins
connected. Campbell Scientific’s SC12 cable is recommended.
The cable for the RS-485 connection is a 2 twisted pair, 22 awg cable.
CSI recommends the CABLE3CBL-L for use with the MD485s.
Compliance
The NL100/105 is encased in metal and meets requirements for a Class A
device under European standards:
APPLICATION OF COUNCIL DIRECTIVE(S)
89/336/EEC as amended by 89/336/EEC and 93/68/EEC.
STANDARD(S) TO WHICH CONFORMITY IS DECLARED:
ENC55022-1; 1995 AND ENC 50082-1: 1992
EUROPEAN REGULATIONS
WARNING: This is a Class A product. In a domestic environment
this product may cause radio interference in which case the user may
be required to correct the interference at the user’s expense.
2. Preparing to Set Up the NL100/105
The NL100/105 must be set up by configuring one or more of the
communications ports for communication with your datalogger or other
devices in the network. To do this, you must establish a direct communication
link with the NL100/105 using a PC computer. You will need a null modem
cable to physically connect the NL100/105 to the computer. The Device
Configurator or a terminal communication software package (such as
HyperTerminal, which ships with Microsoft Windows operating system
software) is used to configure the settings in the NL100/105.
