Programming Enfora GPRS modem to work with the DataNet System (Version 21)

The events listed below (using AT$EVENT command) are for general usage, and can be

removed or edited as required for custom applications. Please read the Enfora event

programming guide for more information on event reporting.

Replace the settings in red bold italics with appropriate strings or numbers. Important

notes are shown in blue underlined text.

1) Connect PC to Enfora serial port. Baud rate is 115200 bps, unless it has been

changed from its default. Use a terminal program (such as HyperTerminal in

Windows) to enter the following commands, or use the Enfora Programming utility

to send the commands as a script file. Use the AT$EVENT? command to read

back the current script settings at any time.

2) AT$AREG=1. Force modem to deactivate network connection.

3) AT&F – Reset modem to factory default settings. Note that this also forces

modem serial port to 115200 bps, and resets event list to default.

4) AT+CGDCONT=1,"IP","apn" – Enter the GPRS APN required by the GSM service

provider. If you get an ERROR response to this command, the modem may

already be online. In that case, issue the AT$AREG=1 command to go offline, and

then try this command again.

5) AT$MDMID="ID" – Enter a modem ID (1-20 characters). This must match the ID

configured in the DataNet server. If this command is not entered, the modem will

use its IMEI ID (programmed in the factory). When sending advanced packets,

there is an option to use an 8 charr ID to reduce packet size.

6) AT$UDPAPI="",port – Modem API port. Enter the UDP port number configured in

the DataGate server. If this command is not entered, the default port (1720) will be

used.

7) AT$APIPWD="password" – Enter a password to prevent unauthorized users

accessing the modem remotely – must be 8 characters (A-Z, 0-9). This

password must also be entered into the DataGate to allow remote control, such as

modifying scripts or polling (requires DataGate version 3.8.3 or later). Use

AT$APIPWD=”” to clear the password.

8) AT$ACKTM=2,30,0 – Modem will retry each packet 2 times, at an interval of 30

seconds if server does not send ack. You may change these values to suit your

application. If you want the modem to reselect its IP address if ack is not received,

change the last parameter to 1, although this may increase network costs.

9) AT$AREG=2 – Automatic network connection.

10) AT$NETMON=10,1,0 – Modem will release connection if network is unavailable

for 10 minutes. After 1 release, network info will be erased. Change the last value

to enable network pings every x minutes. Note: releasing the network connection

may result in increased data usage counts.

11) AT$EVTIM1=x – Timer 1 will trigger every x seconds. In this sample script, Timer

1 and Timer 2 are used to trigger GPS position reports. Using two timers allows

two reporting rates based on vehicle motion, IGN status, etc.

12) AT$EVTIM2=y – Timer 2 will trigger every y seconds.
