3. INTERFACES
Each unit provide
s four interfaces that can be used to connect the unit to
external devices. The interfaces for this model are listed b
1. Relay (Discrete) Interface: This interface offers the essential monitoring and control of the
unit by discrete signals.
2. RS-232 Interface: This interface offers the operator es
unit, using a PC with Term95 or HyperTerminal comm
3
. RS-485 Interface: This interface offers the complete monitoring and control of the SSPB
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). In a Redundant System, if this LED
is NOT LIT, it indicates that the unit is in STAND-BY and in MUTE state. If this LED is
RED lit, it indicates that the unit is in ALARM or in FAULT condition. If this LED is RED
FLASHING, it indicates that the unit is in MUTE state and ON-LINE (in a redundant
system).
If this LED is GREEN lit, it indicates that the unit is functioning properly. In a Redundant
system, if this LED is GREEN, it indicates that the unit is functioning properly and it is in
ON-LINE position. If this LED is GREEN FLASHING, the unit is in good functioning
condition and in STAND-BY NOT MUTE state (in a redundant system).
The LED will flash RED-GREEN when the unit is in DOWNLOAD mode.
3.1 RELAY INTERFACE
The Relay Interface uses a 10-pin circular connector mounted on the unit enclosure. The
connector type is listed in TABLE 5
The pin assignment for this interface is shown in TABLE 7 at page 19.
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 Up-Converter unit.
Pins G and H of the connector are inputs, allowing the user to mute or un-mute the RF path of
the SSPB Up-Converter.
CAUTION:
If pin G is not connected to pin H, the transmission path will remain disabled.
