FIGURE 1. RF400
The RF400 has a 9-pin serial CS I/O port and a 9-pin serial DCE RS-232 port.
The CS I/O port allows the RF400 to connect to a datalogger. The RS-232 port
allows direct PC connection for Setup Menu access and to create a direct
connect RF400 “base station” for point-to-point and point-to-multipoint
communications. Where necessary, a more distant base station can be set up
using short-haul modems or phone modems between PC and RF400.
Base Station power is usually provided by a wall adapter. For a remote RF400,
power is normally provided by the datalogger.
A PC running LoggerNet, PC208W, or PC208 is used for data collection,
program transfer, and other datalogger supported functions. The PakOS
software or a terminal program is used to configure the RF400 radios.
