System Setup

You can in fact continue to use both addVANTAGE versions at the

same time: addVANTAGE 3.4x over the serial line and

addVANTAGE 4 Pro over a TCP/IP network. For installing and

configuring addVANTAGE 4 Pro as well as some additional tips

about migrating from addVANTAGE 3.4x to addVANTAGE 4 Pro,

Configure GPRS usage

Firmware and Routers

The A840 Gateway must have an IMG update to allow GPRS

connections. This firmware must be 3.8.0 or higher. In addition;

the A840 GPRS feature must be activated with the license key!

Look for the string "GPRS" in the license key string.

The new firmware will expect GPRS connections on port 81. Use

your router/firewall and NAT/PAT (Network/Port Address

Translation) to direct incoming connection requests to port 81 and

the private IP of the A840 Gateway.

Configure the A840 for use with GPRS RTU’s

Once the A840 firmware has been updated, the RTU must be

configured for GPRS. Open the Configurator, create a GSM RTU.

Once the device is created. the properties for the new RTU will

allow you to select it

GPRSSECRET <secret>

This has to be set (a 32 bit integer number, 0 to 4294967295). This

has to be set on the RTU as well as on the gateway. This is a sort

of shared secret or password.

Enter the Authorization code; it must EXACTLY match the

GPRSSECRET entered in the RTU (see GPRSSECRET). Check the

"Close connection after polls" check box.

If you want to change the A840 related configuration of a GPRS-

unit via Emu3ap: enter the Authorization code see GPRSSECRET)

as phone number (via Emu3ap's phone command), but precede

the number by one or two asteriscs (*).
