Setting up the rover CDPD modem
Turn off flow control
Use the command
ATS211=1
this ignores DTR.
Use the command
AT\Q0
to turn off flow control. This is not required for the 5700
There are two choices on how you can configure your sage as a rover
- Use the data collectors cell phone support
- Have the modem connect automatically
Recommended method:
Previously it was recommend that you have the modem connect automatically. In pratice I now believe that it is simpler to use the Data collector to control the connection.
Data Collector based setup
In the data collector select Cellular phone as your radio type. Instead of the phone number just enter the IP address and port of the base station. For example 163.254.3.2:5001
Automatic connection
Set the default power up mode
Use the command
ATMD3
To set the default mode on power up
This method can be easier if you are just connecting to one service each time.
Set IP address of the base modem
Use the command
ATS53=xxx.xxx.xxx.xxx/p
Where xxx.xxx.xxx.xxx is the IP address of your base modem
The port (p) is not important, as long as the base and the rover have the same value.
You can use 0.0.0.0 for the address which meansthe rover will work with any base that sends it data. This is the recommended method
Set the rover to Listen for the base
Use the command
ATS83=2
This sets the modem into listen mode.
Store the configuration
Use the command
AT&W
This stores the information in permenant memory, so on power up it is used
There is NO setup required in the normal course of action for the rover unit. It will work automatically when turned on. Assuming the base is broadcasting of course
