Connecting to the CDPD Network
This section provides a quick installation guide to familiarize you with the critical
steps required for successful communication with the CDPD network using a
USWD500 Modem. After you have received the
OK
message in the previous
section “
Verifying the USWD500 Working Status
”, proceed with the following
steps.
Step 1
Set the IP Address and Side Preference
Before the USWD500 Modem will operate on the CDPD network, you must specify
an Internet Protocol Address (IP Address) and a side preference (A or B) for your
network carrier. Specific details are provided in "
General Parameters Setup”
on
Page
20, with the setup procedures described in detail.
These parameters must be set before connecting to the CDPD network. Obtain
these values from your CDPD network carrier or service provider. After you have
determined the appropriate values, refer to "
General Parameters Setup”
on
Page
20
,
for setting the parameters.
Step 2
Verify the status of other parameters
AT commands for setting up other parameters are described in more detail in
“Advanced Parameters Setup”
on Page
23, which includes setup procedures for
communications port parameters, UDP parameters, SPI/SPNI/WASI parameters,
S-Registers, and Sleep Mode parameters. You can either change these
parameters using AT commands or simply use the factory default settings.
