Preparing the ISS and Radiation Shield
The radiation shield must be partially disassembled in order to make necessary
cable connections, and to install batteries in the solar-powered wireless ISS.
The ISS sensors are connected by cables to the Sensor Interface Module (SIM),
located inside the radiation shield. The SIM contains electronics that measure
and store weather values for transmission to the console via cable or radio
waves. The radiation shield's white plastic plates protect the SIM from sun and
other sources of radiated and reflected heat, and from precipitation.
The following tasks are performed while the radiation shield is disassembled:
Check the rain, solar radiation, and UV cable connections to the SIM sensor
Connect the anemometer sensor cable to the SIM
Connect the console cable to the SIM (cabled versions only)
Make power connections to the ISS
Change the Davis Talk ID for wireless communication, if necessary
Verify that your console is receiving and displaying data
Power and test the fan
Opening the Radiation Shield
Open up the radiation shield by separating the top and bottom parts as shown
in the following illustrations.
1. Turn the rain collector side of the ISS upside down.
2. Remove the three wing nuts, lock washers and flat washers located on the
underside of the radiation shield.
