The Strap Code is a quick set key that sets many
modem parameters. Consult the strap code guide for
available strap codes. Parameters set by strap code:
Data Rate
Inner Code Rate
Satellite Framing
Scrambler
Drop and Insert
Outer Code Rate (Reed-Solomon)
Modulation
Network Spec
{50 – 90 MHz, 100 – 180 MHz,
or 950 – 1750 MHz (L-Band)}
Allows the user to enter the Modulator IF Frequency in 1
Hz increments.
{0 to -25 dBm}
Allows the user to enter the Transmitter Power Level.
{ON, OFF}
The DMD20 transmitter will turn off the carrier output
automatically when the modem determines there is a
major alarm. This is done to prevent the carrier from
outputting an unknown spectrum and possibly disturbing
adjacent carriers. This automatic drop of the carrier can
be overridden by masking the alarm that is causing the
fault. This will keep the modulator output spectrum
transmitting, even when the fault occurs.
