5. HARDWARE
After configuring LoggerNet or PC208W, the NL100 and the MD485(s),
you are ready to set up hardware. Attach the Ethernet cable to the
10BaseT port of the NL100. Supply power to the NL100.
The remote MD485(s) connect to datalogger CS I/O ports via SC12
cables. Powering up the datalogger(s) will start the MD485(s) operating.
For transparent communication or PakBus networking, connect the
CABLE2TP cable between the RS-485 ports of the NL100 and the
MD485(s) and you are ready to connect to the datalogger(s). For MD9
emulation, connect the RS-232 port of the NL100 to the RS-232 port of
the base MD485. Connect the CABLE2TP cable between the RS-485
ports of all MD485(s).
