DART 200 CDPD Modem User’s Guide 2 Installation and Setup

Selecting CDPD 1.0 or 1.1 mode of operation

DART firmware Version 3.0.1 and above can operate in either CDPD 1.0 or 1.1 mode; prior firmware versions support only CDPD 1.0. The firmware version can be determined by the ATI1 command.

The default is to operate in CDPD 1.1 mode, but in areas where CDPD

1.1is not yet active, the operating mode can be changed to CDPD 1.0. To set CDPD 1.0 mode, set S-Register 95 to 8 (default is 11) as follows:

1.Enter Service Provider mode with AT^P+51348954.

2.Set S-Register 95 for CDPD 1.0 mode with ATS95=8.

3.Save change with AT&W.

4.Restart to activate the change with AT-R.

To change back to CDPD 1.1 mode, repeat steps 1 to 4, but set

S-Register 95 to 11 instead of 8.

Initial testing

Setup verification

The first step to make the DART 200 operational is to verify the setup by doing the following:

1. Use AT\S? to view and verify the IP Addresses, for example:

at\s?

*NEI 0 = IP ADDRESS 198.225.189.032 GMID 00000 OK

*Means the NEI is active

If you are just starting, there should be no problem here, because the IP Address was just entered. However, if the address needs correction, put the modem into Service Provider mode with an AT^P+51348954 command, then enter the IP Address with an

AT^An.n.n.n.

The GMID is used with multicast operation, the value now should be zero.
