Figure 15: Multiple destination point-to-point network
The point-to-point destination address on the main port of the base unit determines which remote unit the
base is connected to. To change the point-to-point destination address on main port, the follow these steps:
Enable the local command mode on the main port by transmitting the escape sequence (see section
6.5.3 on page 36).
Use the AT command to change the main port point-to-point destination (ATS52=1001).
Return the port to online state using the online command (ATO).
Other configuration parameters which may help in fine tuning the system operation are:
Rx packetiser timers. See page 18 for more information.
Max packet size.
Singlecast retries. See page 24 for more information.
