USING THE 8000 GPRS CRADLE
The 8000 GPRS Cradle is a charging & communication cradle that is specifically designed
for connecting CipherLab 8000 Series Mobile Computers to WWAN via GPRS data services.
Refer to Chapter 4 Programming Your Mobile Computer.
This chapter explains how it works and the three working modes supported by the 8000
GPRS Cradle. Please contact your Internet service provider (ISP) or network operator for
information on GPRS related settings, such as
APN (name of access point that connects the mobile network to the Internet)
IP address (DHCP or static)
User name and password (may be optional, depending on Challenge-Handshake
Authentication Protocol)
For quick deployment, we provide a utility (.SHX) that can be downloaded to your mobile
computer and used to configure, test, and upgrade firmware of as many cradles as you
have. Refer to Chapter 2 Configuring the 8000 GPRS Cradle and Chapter 3 Upgrading
Firmware.
Warning:
It is recommended that the charging devices be operated at room
temperature (18°C to 25°C) for optimal performance. The charging devices
will not charge the battery when the temperature exceeds 40°C.
8000 GPRS Cradle Reference Manual
1.1 HOW IT WORKS
Referring to the flow chart on the next page, LED 2 and LED 3 are used to indicate a
specific stage of initialization, data connection, as well as firmware download. They are
explained below (by number).
1) Initializing
After powering on, the LEDs of Tx/Rx and Link will flash by turns at the time interval
of 0.25 seconds for about 30 seconds, indicating the cradle is in initialization process.
2) Initialization OK
If initialization is done successfully, the LED of Link will flash at the time interval of 1
second, waiting for AT commands.
3) Initialization NG
If initialization fails, the LED of Tx/Rx will flash at the time interval of 0.5 seconds,
indicating an error occurs. For example, it might fail to pass PIN authentication, the
signal strength is weak for the GPRS network, the Access Point name is incorrect, etc.
For details on the specific initialization error, use “AT+ERR?” to get the error code.
Although initialization fails, the cradle can still accept AT commands. In case of the
“ATDT” command, it will re-initialize before dialing out.
4) Dialing out
When in Dial mode (ATDT), the LED of Link will flash at the time interval of 0.3
seconds for about 20 seconds.
5) Connected
When in Dial mode (ATDT), the LED of Link will be green after successfully
establishing a connection.
6) Data Transmission
When in Dial mode (ATDT), the LED of Tx/Rx will flash as long as data transmission
occurs.
7) Download Ready
When in Download mode (AT+DOWNLOAD), the LEDs of Tx/Rx and Link will flash by
turns to indicate the cradle is ready.
8) Downloading
When in Download mode (AT+DOWNLOAD), the LEDs of Tx/Rx and Link will flash
simultaneously to indicate downloading is in progress.
Chapter 1
Using the 8000 GPRS Cradle
8000 GPRS Cradle Reference Manual
1.2 DIAL MODES
When the mobile computer is seated in the cradle, it can send the collected data back to
a remote server, as well as download lookup files, via GPRS.
When dialing out (ATDT), the LED of Link will flash at the time interval of 0.3 seconds for
about 20 seconds. When connected, the LED of Link will be green after successfully
establishing a connection. The LED of Tx/Rx will flash as long as data transmission
occurs.
Note: It is suggested to issue the command “AT” every five seconds for best practice, in
order to check whether the mobile computer is seated in the cradle.
The escape sequence, consisting of three characters “+++”, is used to terminate
the data connection.
1.2.1 GPRS CONNECTION
When initialization is done, issue ATDTxxx.xxx.xxx.xxx:kkkk or ATDT[HostName:Port] to
establish data connection via GPRS. The buffer size of the cradle is 1460 bytes, and data
packet will be sent out as long as it satisfies any of the following requirements:
buffer is full (= maximum packet size is 1460 bytes)
delimiter character is encountered
end of transmission timeout (= no transmission for 5 milliseconds)
Due to the limited memory size, the cradle cannot send three packets at the same time,
and therefore, the third packet will be discarded. We suggest you enable the
Challenge-Handshake Authentication Protocol (CHAP) setting for best practice.
Chapter 1
