Whether the measurements are stored at the primary or sec-
ondary rate, they are stored in a rollover type of memory. When
full, the module overwrites the oldest data with the newest
readings.
The various components of the 2150EX are shown in Figures 1-1
through 1-4. Items referenced in the figures are described in
Tables 1-1 through 1-4.

Description
Latches the module in place. A latch release is located on the
right side of the module.
Upper communication port; used to connect to another mod-
ule, or to a PC running Flowlink software.
Insert into unused communication connector to terminate the
network and protect it from moisture damage. When the com-
munication connector is in use, the cap must be stowed in its
holder to protect the terminating components inside the cap.
The cartridge holds desiccant that dries the reference air. The
filter prevents moisture from entering the reference line.
Illuminates when module communications are active.
Used to connect the module to the 2191EX or 2196EX battery
module, or to another 2150EX module. When the communica-
tion connector is in use, the cap must be stowed in its holder to
protect the terminating components inside the cap.
Used to store the Connector Cap.
