3.2.4 Unit Options
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. The
password is case sensitive. 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: Internal Tx Clock (default)
Options: Internal Tx Clock or External Tx Clock
Switch S2-7 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 2701RC.
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, S2-7 can be
changed to solve the problem.
S2-7

Set to Default Configuration
