Appendix B. Hardware Installation
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.
