FIGURE F-1. Point-to-Multipoint System
F.4 PC208W Configuration
For point-to-multipoint operation the RF401 can temporarily be put into AT
Command Mode by sending a string of three ASCII characters. The default
sequence to enter AT Command mode is:
1. No characters sent for one second (before command character)
2. “+++”characters sent (default command mode entry character)
3. No characters sent for one second (after command mode character)
4. RF401 responds by sending “OK” <CR>
The AT Command mode characters are sent by PC208W along with other
commands to change the base RF401’s Radio Address to talk to the desired
remote RF401 (see point-to-multipoint below).
