Back Panel • 9
Back Panel
The back panel includes the power jack, sample fittings, and a USB PC connector.
Power Jack
The power jack is located in the bottom left corner of the back panel. The plug on the
end of the AC adapter cable mates to it.
Sample Fittings
Three sample fittings are located on the back of the SDM-2009. The AIR fitting is in
the upper left corner and draws air into the SDM-2009. The GAS fitting is to the right
of the AIR fitting and is used to connect the SDM-2009 to a calibration gas cylinder.
Both fittings accept 3/16 inch ID tubing.
An exhaust fitting is located in the upper right corner. It allows routing of the
exhausted calibration gas to a convenient location. This fitting accepts 5/16 inch ID
tubing. Even though the exhaust gas can be routed to an area to be safely dispersed,
the docking station should still be installed in a well ventilated area.
PC Connection
A type B USB connection is located beneath the exhaust fitting on the SDM-2009’s
back panel. It is only used for the PC Controlled configuration and is not used in the
Standalone configuration.
