5. Software Setup
5.1 Point-to-point
Set-up parameters are configured the same for the two RF400s. The RF400
defaults to radio address “0” (zero) which works for many applications.
See Section 4.2 for power supply options.
5.2 Point-to-multipoint
The radio addresses for a base RF400 and its remotes are typically configured
to be different from one another. The base RF400 radio address might be 0,
the first remote’s radio address might be 1, and the second remote’s radio
address might be 2, etc.
For the base RF400 to be able to transmit to a remote RF400, the base’s Radio
Address must be temporarily changed to match that of the remote. The address
change is done by putting the base RF400 into command mode, changing the
address with an ATDT command, and then putting it back into data mode with
the ATCN command. You can accomplish this by entering these commands in
the Generic Dial String in PC208W’s datalogger Setup Connections screen (see
example below).
See Section 4.2 for power supply options.
5.3 Example Setups
The following procedures explain how to build a basic RF400 point-to-point
network and a point-to-multipoint network with base station connected directly
to the PC COM port. The PC should be running LoggerNet or PC208W. The
remote station can consist of an RF400 connected to a datalogger.
5.3.1 Direct PC to RF400 Series Base Station Setup
1. Connect the RF400’s RS-232 port to a PC COM port using a straight
through serial cable Item # 10873, or equivalent. Use a 25-pin to 9-pin
adapter if necessary. This hardware configuration can serve (1) to do the
set-up of the RF400, and (2) for base station communications with
datalogger(s) in point-to-point or point-to-multipoint networks.
2. Run Hyper Terminal TM , Procomm TM , or other terminal emulator program.
a. Baud rate: 9600, 8-N-1
c. Flow control: none
d. Emulation: TTY
e. ASCII (raw)
f. COM1 (direct connect)
3. Power up RF400 (wait two seconds) and press “Program” button for one
second to see the following display.
