Multitech DataTalker DT101 Owner's Manual page 31

The DataTalker knows the type of link device being used by the way a DIP switch is set or by
detecting a device installed on the main PC board. In this configuration, a 56K bps internal DSU
is used for the composite link device, so when the Composite Link Settings menu is displayed, it
is for a DSU:

The internal DSU has three options: speed and clocking. The speed option should match the
DDS line speed. The clocking option depends on how you have set up your link with the
telephone company. If the link is set up as a DDS link, use the default DDS setting. If the link is
set up for the DataTalker to provide the clocking, change the clocking option to Internal. Enter S
and press ENTER to store all configurations.
If you are setting up the composite link for an external composite link device, set up the device
for internal clocking and the type of connection between the device and the DataTalker, i.e., an
RS232 or a V.35 connection.

When you select option 3 in the Configurations menu, the Composite Link Settings - External
Device menu will be displayed. Set the clocking and speed options to match the external device.
The back to back option should remain off. Enter S and press ENTER to store all configurations.
This completes the configuration of both DataTalkers. Disconnect the data/command port from
the terminal or PC and connect it to the router. Place DIP switch position 3 on both DataTalkers in
the up (OPEN) position to change the data/command port over to a data channel.
