2150EX AV Flow Module - Isco

2150EX Area Velocity Flow System
Section 1 Introduction
Rollover Memory
1.2 Identifying Module
Components
Whether the measurements are stored at the primary or secondary
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.

4 Desiccant Cartridge and
Hydrophobic Filter
Upper communication port; used to connect to another module,
or to a PC running Flowlink software.
Insert into unused communication connector to terminate the
network and protect it from moisture damage. When the communication
connector is in use, the cap must be stowed on 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.
5 Communication Indicator Illuminates when module communications are active.
6 Communication Connector
(shown plugged)
Used to connect the module to the 2191EX or 2196EX battery
module, or to another 2150EX module. When the communication
connector is in use, the plug must be stowed in its holder
to protect the terminating components inside the cap.
