Serial Port Communications and Commands
Command Explanations
At the prompt, enter the ACC command:
=ACC <Enter>
Because the main board jumper is not in place, the relay asks for the Access
Level 1 password to be entered:
Password: ? @@@@@@
The relay is shipped with the default Access Level 1 password shown in the
table under the PAS Command (Password). At the prompt above, enter the
default password and press the <Enter> key.
The relay replies:
FEEDER 1 Date: 03/05/96 Time: 08:31:10.361
STATION A
Level 1
=>
The => prompt indicates that the relay is now in Access Level 1.
If the entered password is incorrect, the relay asks for the password again
(
Password: ?). The relay will ask up to three times. If the requested password
is incorrectly entered three times, the relay closes the ALARM contact for one
second and displays the following message:
Invalid Password
Access Denied
WARNING: ACCESS BY UNAUTHORIZED PERSONS STRICTLY PROHIBITED
Access Level Attempt (Password Not Required). Assume the
following conditions exist:
➤ main board password
➤ jumper JMP22 = on (passwords not required to enter higher
access levels)
➤ Access level = 0 (prompt =)
At the computer screen prompt, enter the ACC command:
=ACC <Enter>
Because the main board jumper is in place, the relay does not ask for a
password; it goes directly to Access Level 1. The relay responds:
FEEDER 1 Date: 03/05/96 Time: 08:31:10.361
STATION A
Level 1
=>
The => prompt indicates that the relay is now in Access Level 1.
