Check SIM Sensor Connections
5
Open the SIM Box
1. Locate the white box with the solar
panel containing the SIM on the front of
the ISS unit. The cabled model does not
have a solar panel.
2. Locate the white tab at the bottom cen-
ter of the SIM box cover.
3. Lift the tab away from the box while
sliding the cover up.
Look on the side of the SIM box. The
box cover can be easily removed from
the box when the alignment indicator
on the cover is lined up with the align-
ment indicator on the box
4. Lift the cover off the box, being careful
not to stress the solar panel cable when
removing the cover.
The SIM and sensor connectors are
visible once the SIM cover has been
removed.
Note: See “SIM Board Display and Contents” on page 29 for information on locating the components
and points of interest on the SIM board.
Optional: Disconnect the solar panel
connection
The solar panel on the box cover is
connected to the SIM by a wire. If the
cover cannot be set aside while still
connected to the SIM box safely, it
should be disconnected from the SIM
box. To disconnect the solar power
connection:
1. Locate the brown connector for the
solar power wire.
2. Pull the connector outward off the
brown solar power tab. The solar
panel is no longer connected to the
SIM.
3. Set the SIM cover aside.
Check the Factory Installed
Sensor Connections
1. Verify that the rain collector and temperature/humidity sensor cables are plugged
into the receptacles labeled RAIN and TEMP/HUM on the SIM.
2. If the station includes UV and/or solar radiation sensors, verify that the sensor
cables are plugged into the receptacles labeled UV and SUN on the SIM.
