If your screen seems to display garbled informa-
tion first check your communication program
settings to make sure “Emulation” and “Telnet
Terminal ID” are both set to “ANSI”. You may
have also started your communication program
right in the middle of the checkback module
saying something. To clean it up, clear the screen
on your computer (there should be some
command or mouse click in the communications
program to do this) and give the checkback
module a couple of seconds to redisplay.
At the password prompt (Enter password:), enter
your password and press the ENTER key. The
default password is "pulsar".
After you enter your password, the module
displays the general settings on your computer
screen. The module you are logged on to is identi-
fied at the top of the screen. Fig. 16-5 shows a
sample screen.
The box in the upper left corner gives some idea
of the amount of noise on the carrier line. When a
checkback module receives a spurious message, it
is usually due to line noise. The "Bad Msg Rate"
shows how many spurious messages a module has
seen in the last fifteen seconds. Also, normal noise
changes to “high noise” if a module has seen a
high number of spurious messages within a two-
minute period. If the noise level
gets too high, you will have
problems communicating between
checkback modules, and non-
checkback communications may be
affected as well.
The box in the upper right corner
shows the module's current time
and date. Beneath that you can see
the amount of time elapsed since
the last checkback test was sent or
received. This timer is reset when a
module is powered up.
Step 5. Set the password.
Now is a good time to set your own
password. You can change the
password at any time using the "set
password" command (see "Issuing
Checkback Commands" later in this
chapter for complete instructions). Passwords can
be from 0 to 10 characters long and are not case
sensitive. That is, the module sees no difference
between "ABC" and "abc". You can use both
numbers and letters in a password, e.g., "abc123".
To change the password from "pulsar" to "mypass-
word", for example, type the following on the
command line (Enter command:) and press the
ENTER key:
set pwd mypassword
After you enter your new password once (or no
password) the checkback module asks you to re-
enter it for verification. When you re-enter it, the
module completes the password change and tells
you "Command Accepted".
Setting a password to nothing (i.e., just entering
set pwd and pressing the ENTER key, then
responding to the verification prompt by pressing
ENTER again) disables the password system.
Then just the ENTER key or any entry becomes a
valid password. If you disable the password, the
module flashes this warning: "Note: password will
be disabled for this module".
For help recovering a forgotten password, see
"Recovering Your Lost Password" in section
16.5.7.
