Making Simple Settings Changes
Example 3.2 Leaving a Note in the Relay
For this example, assume you are testing a line, but you will be away for a
few days. You want to leave your colleague, Marius, a note telling him where
you left the drawings and settings. Use the Notes function in the relay to
leave the note, as shown in Figure 3.18. All relevant procedures in this sec-
tion assume that you have successfully established communication with the
relay. In addition, you must be familiar with relay access levels and pass-
words to change the default access level passwords. Furthermore, Step 1
below applies to all relevant tests, and is not repeated for each test.
Step 1. Prepare to control the relay at Access Level 2.
a. Using a communications terminal, type ACC <Enter>.
b. Type the Access Level 1 password and press <Enter>.
You will see the Access Level 1 => prompt.
c. Type 2AC <Enter>.
d. Type the correct password to go to Access Level 2.
You will see the Access Level 2 =>> prompt.
Step 2. Access the Notes settings.
a. Type SET N <Enter> to access the Notes settings.
b. At the Line 1 settings
? prompt, type the Line 1 text shown
in Figure 3.18 (as many as 70 characters without wrap), and
press <Enter>.
The relay verifies that this is a valid entry, then responds
with the next line prompt
2: followed by the settings ? prompt.
Step 3. At the Line 2 settings
? prompt, type the Line 2 text shown in
Figure 3.18.
Because there are more than 70 characters, the relay rejects the entry.
Re-enter the text, but keep the number of characters at 70 or
fewer.
Step 4. After the last entry, type END <Enter>.
This tells the relay that you have completed the setting change.
Step 5. Type Y <Enter> at the prompt
Save settings (Y,N) to save
the settings.
