 What each sensor is.

 When to collect the data from each sensor.

 How to process the collected data.

 Which data values define a single data record to be logged into logging memory.

 When to log into memory and/or transmit the data record.

 Whether to generate one or more alarm messages.

 Which telephone numbers to dial (up to 4 telephone numbers), if an alarm message is to be sent via a

telephone modem.

 What (if any) types of communication devices are connected to the ZENO®-3200 (a one-way radio,

two-way radio, telephone modem, cellular modem, GOES or ARGOS transmitter).

To define the configuration within the ZENO

-3200 (and to retrieve data logged), the user interactively

communicates with ZENOSOFT

using its built-in user interface. The user interface contains a set of

interactive menus that allow the user to create a new configuration or modify an existing configuration.

1.3. ZENO

-3200 SPECIFICATIONS

1.3.1. Analog Inputs

Seven (7) differential or fourteen (14) single-ended inputs offer choices for sampling performance.

 Ultra-high resolution: ±18-bit at up to two channels/second with 50/60 Hz noise rejection.

 High resolution: ±15-bit at up to 10 channels/second with 50/60 Hz noise rejection.

 Low resolution: Two (2) channels available at ±12-bit A/D at 10,000 conversions/second.

Accuracy and linearity are provided over a wide temperature range as follows:

 Linearity: ±0.001% (-40°C to +60°C).

 Basic radiometric accuracy: ±0.05% (-40°C to +60°C).

 Wide dynamic input range: ±5 mV to ±5 V in 10 ranges.

All analog inputs are fault-protected against shorts, overvoltages, transients and ESD.

 Up to four multiplexer boards can be added, each allowing 32 additional single-ended or 16

differential inputs.

1.3.2. Digital I/O Ports

 Six (6) Schmidt trigger conditioned inputs.

 Two (2) comparator inputs.

 Six (6) general purpose input or output channels (inputs TTL with pull up resistor, outputs 1 - 5 VDC

high impedance).

 One (1) switch closure (event counter).

Digital inputs can be configured for frequency, period, count, or event counting. Digital outputs can

provide control or alarm signals.

 Count inputs: Up to 65536 counts at 0.005% accuracy.
