FIGURE I-1. LoggerNet Point-to-Multipoint Setup
4. HARDWARE
After configuring LoggerNet or PC208W and the RF400s you are ready to
set up hardware. The PS512M null-modem connectors (it’s not important
which connector goes to which unit) connect via SC12 cables to the
COM210 and the base RF400 CS I/O port. Connect the site phone line to
COM210. Connect power to PS512M. Connect antenna to RF400.
When you turn on the PS512M supply, the RF400 receives 12V power
and you will see the LEDs light in their power-up sequence.
Remote RF400s normally connect to datalogger CS I/O ports via SC12
cables. Powering up the datalogger will start the RF400 operating. Install
an antenna (or antenna cable and yagi or collinear) and you are ready to
collect data.
