7.5.2 CHANGING THE PASSWORD
In addition to its address, each multiplexer may be assigned a password. The password of a multiplexer
must be known in order to make any remote setup changes once its remote port(s) have been locked.
All of the multiplexers in a given network may be assigned the same password or different passwords,
depending on the user's requirements.
Valid passwords consist of any string of letters and numbers up to 16 characters long.
Like the network address setting, the password is actually a CM4 parameter rather than a multiplexer
parameter. The password is normally used on a one-per-multiplexer basis; that is, both CM4 modules
in a given drop/insert multiplexer are generally assigned the same password. However, this is not a
requirement.
When shipped from the factory, each IMUX 2000 multiplexer is assigned a "null" password - that is,
the parameter field of an UNLOCK command must be left blank to unlock the remote port. To change
the password of a given CM4 module, issue a SET command of the following general form:
<Address>:<Subaddress>:SET:PASSWORD=xyz;
where "xyz" is the new password.
For example, to set the password of a CM4 module to "GREEN" in a terminal multiplexer with an
address of 7, issue the command:
7:TERM:SET:PASSWORD=GREEN;
Or, to set the password of both CM4 modules to "BLUE" in a drop/insert multiplexer with an address
of 8, issue two commands:
8:DI-A:SET:PASSWORD=BLUE;
8:DI-B:SET:PASSWORD=BLUE;
If the password is lost or forgotten, the multiplexer can still be unlocked locally using the Lock
function in the SIO Group.
