To change the password for Access Level 1 to Bike enter the following:
The relay responds by setting the password, pulsing closed the alarm relay, and transmitting
the response "Set."
After entering new passwords, type PASSWORD <ENTER> to inspect them. Make sure
they are what you intended and record the new passwords. There is no communications
procedure to access the relay without the passwords.
Passwords can be any length up to six numbers, letters, or any other printable characters
except delimiters (space, comma, semicolon, colon, slash). Upper and lower case letters are
treated as different characters. Examples of valid, distinct passwords include:
OTTER otter Ot3456 +TAIL+ !@#$%^ 123456 12345. 12345
If the passwords are lost or you wish to operate the relay without password protection, install
JMP103 on the main board. With no password protection, you may gain access without
knowing the passwords and view or change current passwords and settings.
SET
SET allows entry of relay settings. At the setting procedure prompts, enter new data or press
<ENTER>
to indicate no change.
The SET command prompts you for each setting. The relay checks new settings against
established limits twice. If the setting is within primary setting range, the relay prompts you
for the next setting. Press
<ENTER>
to retain an existing setting.
The first check is a primary setting limit check, the second is a secondary setting limit check.
The primary check is intended as a rough guideline for individual settings and ensures that
settings fall within a reasonable range. The secondary check compares the entire group of
settings against the individual secondary setting limits shown in Section 2: SPECIFICA-
TIONS.
