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
2710RC. Please review the information provided with your DTE equip-
ment 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 2710RC. 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. 

Service Information

If you need to contact us for help, you can view the Service

Information screen. Here is what it looks like:

Clear Errors

The Model 2710RC records FIFO and Clock Slips and displays

them on the right side of the screen. Slips can be an indication of
clocking configuration problems. Selecting 'h' <spacebar> will clear the
errors displayed. Note: When the units configuration is changed there
may be a group of slips introduced when the new configurations are
being implemented. If you would like to check for slips, make your con-
figuration changes, then clear any errors counters, then check from
time to time for errors.
