DMD2401 LB/ST L-Band Satellite Modem and ODU Driver
{32 - 255}
Allows the user to select the Remote Port Multidrop
Address.
{300, 600, 1200, 2400, 4800, 9600, 19200}
Allows the user to select the Remote Port Baud Rate.
{None, Tx, Rx, Tx/Rx}
Allows the user to enable/disable the 2047 Pattern Test.
Tx enables the Transmit Pattern Generator.
Rx enables the Receive Pattern Generator.
Tx/Rx enables both.
{0000 - 9999}
Allows the user to select the number of errors to insert.
Once the number of errors to insert has been selected,
pushing 'Enter' causes the number of errors shown to be
inserted in the data stream.
-9
{No Sync, nnnn x 10
}
Shows the measured BER for the 2047 pattern.
{No Sync, nnnnn}
Shows the number of errors detected by the 2047
pattern checker.
(Ent = Y, Clr = N)
Restarts the 2047 BER Test.

Terrestrial Loopback is performed at the Terrestrial
Interface.
Tx Terr – Sends Tx Terrestrial Data to Rx Data Out.
istant Loop) Sends received satellite data to
the Modulator for transmission to the distant
end.
Tx/Rx Terr – Enables both.
Baseband Loopback is performed at the interface
between the Baseband Processor Card and the Modem
Card. This ensures Framer/Deframer integrity.
Tx BB – Sends Tx Data to the Receive Input to the BB
Card.
Rx BB – Sends Rx Data from the Modem Card to the Tx
Data Input to the Modem Card.
Tx/Rx BB – Enables both.
IF Loopback loops the IF Output of the Modulator to the
IF Input of the Demodulator.
