Configuration
GENERAL
The configuration options allow you to select various operating features
that program the DDS/MR64 to your network conditions.
Most configuration options are selected by front panel pushbuttons.
Option descriptions state if an option is not available. For instance, if
synchronous is selected, bits per word does not appear. Hard straps and
a dip switch on the PC board configure signal ground and the DTE inter-
face.
CONFIGURATION ON POWER-UP
After installation, turn the power on. The DDS/MR64 will perform a
self test. If the test fails, the LCD displays ERROR. If an error occurs
ensure it is consistent and then refer to Maintenance.
If no error occurs the LCD advances to one of three displays:
NO SIGNAL SYNC DTE
RATE
1
ASYNC DTE SYNC RA RATE
1
RATE

RATE
2
ASYNC RA 1200

In the DDS mode, NO SIGNAL means there is no connection to the
DDS network. When used as a limited distance modem, NO SIGNAL
means there is no data connection to another modem. Press HOME. The
LCD advances to the first option selection.
