DMD20/20LBST Universal Satellite Modem
The DMD20 LBST (Figure 1-2) offers additional features that are not included in the standard
DMD20 Modem. The features included in DMD20 LBST serves as an interface between the
indoor unit (DMD20 LBST) and the outdoor units (consisting of the BUC and LNB). The output
frequency of the LBST is 950 to 2050 MHz. It does not offer a 70 MHz output that is included in
the standard unit. The LBST can supply voltage and 10 MHz reference to the BUC and LNB via
the IFL Cable. The output from the Tx Port consists of the L-Band output frequency, high-stability
10 MHz reference, FSK communications and either 24 or 48 Volts to the BUC. The Rx Port
consists of the L-Band input frequency, high-stability 10 MHz reference and 13, 15, 18, and 21
volts.
The LBST has the capability to enable and disable the BUC/LNB voltages and 10 MHz reference
via the front panel. In addition, monitoring features provide verification of system status. The
LBST monitors both the current and the voltage at the output of the Tx and Rx Ports, thus
allowing the user to monitor the status of both the indoor units and outdoor units.
