3.2.4 Unit Options

The Unit Options screen looks like this (factory default):

aHeader Line 1 &

bHeader 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.

The Loop Timeout setting can be set to one of the following:

00:05 =

five minutes

00:10 =

ten minutes

00:15 =

00:30 =

intervention.

eTx 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.
