NSTALLATION
6.3.3.1 Single Unit
1. Bolt the SSPB unit at the antenna hub by using the six mounting holes provided by the
enclosure; see
Figure 1
at page 16.
2. Position the interconnecting waveguide system flange so that it aligns precisely with the
waveguide flange of the SSPB RF output port.
3. Install the supplied waterproof gasket (supplied in the packing list
)
on to the interconnecting
waveguide flange.
CAUTION:
If the waveguide is intended to be pressurized, do not exceed 2-3 psi pressure,
in order to protect the inside pressure window installed by Advantech Wireless.
4. After alignment verification, loosely attach the interconnecting waveguide on to the RF
output port using the hardware provided in the shipping kit.
5. Carefully tighten all bolts (in opposite pairs rather than sequentially around the perimeter of
the flange) so that the connection is firm.
CAUTION:
Do not over-tighten the waveguide flange screws. Over-tightening the bolts
may cause the stripping of the threads or distort the mating flange. Recommended torque is
15 in-lbs for #6-32 bolts.
6. Ground the SSPB unit by attaching a #6 gauge copper wire to the ground terminal provided
by the unit enclosure to a properly grounded structure.
7. If it is desired to use the Relay interface, then attach the interconnecting cable fabricated per
Section 6.3.1
to the Relay connector of the SSPB unit. Connect the free end of the
interconnecting cable to the operator’s monitor and control system.
NOTE:
Whether this interface is being used or not, it is necessary to connect pin G of
the Relay connector to pin H (common) in order to enable (un-mute) the
transmission path. If pin G of this interface is not connected to pin H, the
transmission path of the unit will remain muted.
8. If it is desired to use the RS-485 interface, then connect the interconnecting cable fabricated
per
Section 6.3.1
to the RS-485 port of the SSPB unit.
9. If it is desired to use the RS-232 terminal mode, then:
a. Connect the interconnecting cable fabricated per
Section 6.3.1
to the RS-232 port of the
SSPB unit.
