5. INTERFACES
Each unit provides four interfaces that can be used to connect the unit to several optional external
devices. The interfaces for this model are listed below:
1.
Relay (Discrete) Interface:
This interface offers the essential monitoring and control of the
Block Up-Converter by discrete signals.
2.
RS-232 Interface:
This interface offers the operator essential monitoring and control of the
Block Up-Converter, using a PC with Term95 or HyperTerminal communications programs.
3.
RS-485 Interface:
This interface offers the complete monitoring and control of the SSPB
Block Up-Converter and provides the communication and remote control through the RS-485
serial communication port in packet mode. The system may be connected to a Monitor &
Control Panel or to a Network Manager System.
4.
RF Output Monitor Interface:
This interface provides a sample of the output power of the
unit through a 40dB coupler.
5.
TX LED
: a green/red LED indicating the state of the transmission path.
•
If this LED is not lit, the unit is not powered (or the power supply failed).
•
If this LED is RED lit, it indicates that the unit is in FAULT or ALARM condition.
•
If this LED is blinking RED, it indicates that the unit is in MUTE state (following a
MUTE command).
•
If this LED is GREEN lit, it indicates that the unit is functioning properly.

NTERFACE
The
Relay Interface
uses a 10-pin circular connector mounted on the Block Up-Converter
enclosure. The connector type is listed in
TABLE 5
at page 20 and the location is shown in
Figure 3
at page 20. The pin assignment for this interface is shown in
TABLE 6
at page 22.
Pins A, B and C of the connector are of Form-C relay type outputs that provide for the user an
indication informing the status of the transmission path of the SSPB unit.
Pins D, E and F are disabled (not used) for these units.
Pin G and H of the connector are inputs, allowing the user to mute or un-mute the RF path of the
SSPB transmission.
CAUTION:
If pin G is not connected to pin H, the transmission path will remain disabled.
