9522B Iridium Satellite Modem and COM9522B Interface

Appendix B. Hardware Installation

The hardware shown in this appendix consists only of hardware listed in

TABLE 1-1 . Although it may be possible to use other hardware, it will not be

addressed in this appendix.

WARNING

Do not connect power to either modem until installation is complete, as damage to the equipment may occur.

B.1 SIM Card Installation

These installation steps apply to both the base and remote modems. Be sure the correct card is installed in the proper modem. Start by removing the cover

on the top of the modem (FIGURE B-1 ). This will require the use of a 5/64

Allen wrench.

Open the card slot by pushing the card holder away from the end labeled

“Lock”, until it is able to flip up. Place the card in the slot in the proper

orientation as shown in FIGURE B-1 . The card notch will need to line up with the notch of the card slot. Close and lock the card slot into place (FIGURE B-2

and FIGURE B-3 ). Once complete, replace the housing cover.

B.2 Antenna Installation

These instructions apply to both the base and remote stations. This installation does not have to precede the modem installation. It should be conducted in the most convenient and logical order.

The installation of the 30741 antenna and cable should begin by feeding the antenna cable through the nut, then spacer, and finally antenna mount

(FIGURE B-4 ). Next, loosen the four Phillips screws at the base of the antenna

and separate the two pieces. Feed the antenna cable through the bottom half

and secure the cable to the connector on the top half (FIGURE B-4 ). Once the

cable is in place, reattach the bottom half of the antenna and secure the four

Phillips screws. Be sure to use the alignment notches on the two halves before securing the antenna together.

B.3 9522B Modem Installation

The base station installation should be conducted before proceeding to the field to conduct the remote station installation. With the base station installed first, it will provide the opportunity to test the communications from the base station before going to and/or while still in the field. If there is a malfunction, you may be able to address the problem without having to return to the remote station.

The modem installation should employ the following steps:

1.

Secure the 30627 mount to the 9522B interface. Secure this assembly in the enclosure in an appropriate location. Be sure to keep in mind all cable runs (that is, antenna, power/control, and interface).

2.

Connect the ribbon cable of the 9522B interface to the modem. Connect the other end of the ribbon cable to the COM9522B.

3.

Connect the 10873 serial cable (base station) to the data port of the interface to the PC serial port.

4.

For the remote station, connect the 18663 serial cable between the

COM9522B data port and the datalogger, unless using datalogger’s CS I/O

port (refer to FIGURE 1-3 ).

5.

Connect the antenna cable to the “ANT” connector of the modem. Use the

18436 right angle adaptor between the antenna cable and modem to reduce cable strain.

6.

Connect the bare leads of the COM9522B to datalogger and power supply.

Start your connections with the power control leads. Be sure power is off at the power supply when making these connections.

Once all the items are attached, power can be applied to the modem.
