SSPB-Ci60
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 or of the unit, 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 or of the unit and provides the communication and remote control
through the RS-485 serial communication port in packet mode. The unit 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 40 dB 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). In redundant
systems, if this LED is not lit it indicates that the unit is in STAND-BY and in MUTE.
•
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. In redundant
system if the LED is GREEN lit indicates that the unit is ON-LINE. If it is blinking
GREEN it indicates that the unit is in STAND-BY and NOT MUTE (RF ON).

NTERFACE
The
Relay Interface
uses a 10-pin circular connector mounted on the Block Up-Converter
enclosure. The connector type is listed in
at page 19 and the location is shown in
at page 19. The pin assignment for this interface is shown in
at page 21.
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.
