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 telem-

etry 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 (Drau, Linux 2.4.0-rmk2-

bluemug1-ges5)

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, it is strongly recommended to change it.

For more details on how to change it, see “Changing Pass-

words” on page 19.

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.
