1. Using the proper mounting hardware and the non-pivoting slide kit (see TABLE 20 at page
46), install the SSPB on to the rack with the waveguide output facing the rear.
2. For a pressurised waveguide system install a pressure window at the RF output port of the
SSPB.
3. Attach a waveguide gasket (see TABLE 20 at page 46) on to the groove of the interconnecting
waveguide system flange.
4. Position the interconnecting waveguide system flange so that it aligns precisely with the
waveguide flange of the RF output port (J7).
5. After alignment verification, loosely attach the interconnecting waveguide on to the RF output
port using four #10-32 x 1/2 inch screws and four #10 lock washers (see TABLE 20 at page
46). Finger-tight all screws.
6. Tighten all screws around the RF output port using a ‘star’ pattern to achieve uniform contact
across the entire surface of the flange.

ONNECTIONS
The connector locations referred to in this Section are shown in Figure 5 at page 24. The
electrical interconnections for the stand-alone unit consist of the Discrete Interface, RS-485 Serial
Interface, RS-232 Serial Interface and the AC power.
5.3.3.1 Discrete Interface
If it is desired to use this interface, then construct an interconnecting cable by using the proper
mating connector as described in
TABLE 6 at page 23 and with the correct pin assignment as
listed in TABLE 3 at page 19. Attach the interconnecting cable with connector to port (J3) of the
SSPB and the user’s monitor and control system.
NOTE: Whether this interface is being used or not, it is necessary to connect pin 1 of
connector (J3) RELAY to pin 5 in order to enable (un-mute) the unit. If pins 14 and
5 of this interface are not connected together, the unit will remain muted.
5.3.3.2 RS-485 Interface
If it is desired to use this interface, then construct the interconnecting cable by using the proper
mating connector as described in
TABLE 6 at page 23 and with the correct pin assignment as
shown in TABLE 5 at page 20. Connect the free end of the interconnecting cable to the operator’s
monitor and control system.
If remote control through this interface is unnecessary, leave the port disconnected.
CAUTION:
Over-tightening the bolts may cause the stripping of the threads or distort the
mating flange.
