9 • Description
module is the last one in the flow system, it is plugged with a push-on
plug that is supplied with the docking station.
A two port exhaust routing fitting is located in the upper right corner of the
back of the DM-2001 and DM-2003 modules. It allows routing of the
exhausted calibration gas from all DM-2001 or DM-2003 modules to the
last module so the exhaust gas can be safely routed to a convenient
exhaust location. The DM-2009 module has only one exhaust fitting.
Exhaust from the DM-2009 may only be routed to an exhaust location
and cannot be routed to another module.
NOTE: 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.
All three types of modules also include a 10-position rotary switch, the ID
switch, above the right DB-15 connector, and a 2-position slide switch,
the terminator switch, above the left DB-15 connector. The ID switch sets
the ID number of a module from 0 - 9, for a maximum of 10 module IDs.
The terminator switch is set to the down position if the module is the last
module in the system and to the up position for any other module.
