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”
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).
