Specifications

DMD20/20LBST Universal Satellite Modem User Interfaces
MN-DMD20-20LBST Revision 14 4–24
REF FREQ SRC {INTERNAL, EXTERNAL, HIGH STABILITY}
Allows the user to select the Frequency Reference Source. High
Stability is only displayed if the appropriate hardware is detected.
REF FREQ (MHz) Allows the user to select the reference clock frequency in MHz.
BB RELAYS {IBS ALMs, IBS/MNR ALMs, IBS/MNR/MJR ALM, RTS
ALARM}
IBS ALMs: Only supports IBS prompt and service alarms.
NOTE: THE FOLLOWING MENUS ARE ONLY SUPPORTED
IN CLOSED NETWORK
IBS/MNR ALMs: Only supports IBS prompt and service alarms
and minor alarms
IBS/MNR/MJR ALM: Only supports IBS prompt and service
alarms, minor and major alarms.
RTS Alarm: Allows contact closures to be activated when the
carrier is configured for RTS signaling. Refer to Radyne App
Note 230 for addition information on utilizing this feature as
Keyline Operation.
TX ASYNC MODE (menu)
TX ASYNC MODE {ES-ES, ESC ENHANCED}
ES-ES is the normal IBS Async Channel. ESC Enhanced can
be selected in Closed Net and uses the Overhead Signaling
bytes in the IBS Overhead to pass asynchronous data. This
menu is not available when SCC is selected.
ES INTERFACE {RS-232, RS-485}
Allows the user to select the interface type.
ES BAUDRATE {150 – 1024} For IBS ES to ES
{150 – 19200} For ES to ES Enhanced
{150 – 115200} For SCC Communications
ES to ES : Fixed Baud Rate based on IBS Network
Specification. Available rates are listed in Table 3-3.
ES to ES Enhanced: Allows user to select the Interface Baud
Rate. This selection will allow the user to set rate as listed in
Table 3-3.
SCC: Allows user to select the interface Baud rate. Interface
Rate must be equal to or greater than the In-Band Rate.
ES BITS/CHAR {7, 8}
Allows the user to choose between 7 or 8 bit data.
RX ES ENHANCED (menu)
RX ASYNC MODE {ES-ES, ESC ENHANCED}
ES-ES is displayed when IBS Network Spec is selected. ESC
Enhanced can be selected in Closed Net and uses the Overhead
Signaling bytes in the IBS Overhead to pass asynchronous data.
This menu is not available when SCC is selected.
ES INTERFACE {RS-232, RS-485}
Allows the user to select the interface type.
