Determining MAWS Operation Mode

You can watch the status LED to determine the MAWS operation

mode. The LED is located on the MAWS logger board and it is visible

through the logger cover.

Establishing Terminal Connection

All MAWS software aided troubleshooting is performed using the

service terminal connection. Some of the operations can be executed

semiautomatically by the MAWS Terminal software, some require

entering the commands manually.

To connect your computer to a MAWS serial port, proceed as follows:

1. Start the MAWS Terminal program on your PC.

2. Set the communication parameters: 9600, N, 8, 1.

3. Give the command open (if the connection is not already open).

Figure 147 on page 189 shows the pin order for the terminal connector.
