CHAPTER 3

Advanced Functions

Stopping and Starting the Telemetry Gateway

The telemetry gateway has a built-in rechargeable battery that is

software controlled. If for some reason you need to stop the

telemetry gateway (for example, shipping for service or storing for

longer time spans), you need to shut it down by switching off the

battery internally, then unplugging the power cable. Proceed as

follows:

1. Shut down addVANTAGE and log into the gateway by means

of a communication terminal (for example, Hyperterminal in

Windows, Zterm or BlackNight on a Mac, or minicom in

Linux). Use the standard parameters:

• 19200 baud

• 1 stop bit

•No parity

• Hardware protocol

• Send CR after LF.

A login prompt such as the following appears:

Telemetry Gateway A840 Version 3.8

A840 login:

2. At the A840 login prompt, type root.

3. At the password prompt, type 840sw.

Note: The default root password is programmed at the factory. For

security reasons, Adcon strongly recommends that you

change it. To do so, see “Changing Passwords” on page 55.

4. The > prompt appears. Type halt.

5. Several messages appear on your terminal. After you see the

last message shown below, you can unplug the unit from the

power outlet, because the internal battery is now off.

The system is going down NOW !!

Sending SIGTERM to all processes.

Terminated.

Sending SIGKILL to all processes.

The system is halted. Press Reset or turn off
