3.3.6 Unit Information
The Unit Options screen looks like this (factory default):
Header Line 1 & Header Line 2
Headers 1 and 2 are provided for easy identification of your unit
after installation. You may want to give each unit a unique name via
the header lines to help distinguish one unit from another. You can
enter a header up to 40 letters long. Two lines provide 80 letters for
your use. That’s a lot of flexibility!
Password
The Password facility provides security by allowing only those who
know the correct password to configure the unit via the control port.
You can still configure the unit via the DIP switches. The password can
be up to 16 characters long, with no restriction on the combination of
characters you can use, so be sure to remember the password. If you
lose your password, you will lose the ability to access the unit via the
control port.
Loop Timeout
The Loop Timeout setting can be set to one of the following:
00:05 = five minutes
00:10 = ten minutes
00:15 = fifteen minutes
00:30 = thirty minutes (default setting)
00:45 = forty-five minutes
01:00 = one hour
01:30 = 90 minutes
02:00 = two hours
03:00 = three hours
NEVER = forever—the unit will remain in loopback without user
intervention.
Tx Data Clock
This option selects the clock that is used to accept the Transmit
Data from the DTE interface. Standard DTE interfaces will transmit
data with respect to the External Clock. In some cases a DTE interface
will transmit with respect to the Transmit clock sent out from the 2720.
Please review the information provided with your DTE equipment for
more information on its' operation. In most cases when there are errors
on the line only in the direction of the transmit data either Tx Data
Clock or Tx Clock Invert can be changed to solve the problem.
Tx Clock Invert
This option allows the user to invert the transmit clock originating
in the 2720. When Tx Data Clock is set for transmit clock, it may be
necessary to invert the transmit clock to allow for cable delays.
Set to Default Configuration
You may set the NetLink-T1™ to its factory default configuration,
except for the header lines and the password, by executing the Set to
Default Configuration command.
