NSTALLATION
6.3.3.1 Single Unit Installation
1. Bolt the SSPA unit at the antenna hub by using the six mounting holes provided by the
enclosure, see
2. Position the interconnecting waveguide system flange so that it aligns precisely with the
waveguide flange of the SSPA 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 SSPA 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 SSPA 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
to the RS-485 port of the SSPA unit.
9. If it is desired to use the RS-232 terminal mode, then:
