5.3 RS-485 INTERFACE
This serial communication interface provides access to all monitor and control functions for the
SSPB Block Up-Converter.
The RS-485 interface must be connected to the Network Management System (NMS). The
NMS will have access to both units, discriminating them by address.
The interface uses a 6-pin circular connector mounted on the SSPB unit enclosure. The type of
mounting connector is listed
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 8
.
If this interface is being used, an interconnecting cable with the proper mating connector must be
fabricated.

5.4 REDUNDANT INTERFACE
The
Redundant Interface
connections are made with a 26-pin circular connector mounted on
the SSPB enclosure. The connector type is listed in
TABLE 5
at page 20 and the location is
shown in
Figure 3
at page 20. A redundant system cable is provided with the redundancy kit
that provides the interconnection between the two SSPB units and the waveguide switch.

NTERFACE
This RF output sample port is located at the Mon connector, which is mounted on the SSPB
enclosure. The type of mounting connector is listed in
TABLE 5
at page 20 and the location is
shown in
Figure 3
at page 20. This interface is used for the independent monitoring of the SSPB
output.
A table of the coupling factor versus the frequency is provided with each unit. Note that
because this port is located before the band-pass filter (BPF) the signal on this port may contain
spurious signals and harmonics. This port should only be used for output power monitoring (via
an external power meter) or should be kept capped if not used.
