Sensor Items for Record 1 of 1:
Item 1: Sensor Type Code 0 (No Sensor)
>
The line items for each Sensor Record usually represent the same type of information. This simplifies the
task of configuring each sensor type, but since different sensor types have different requirements, not all
line items appear for the different sensor types.
Each line item in a Sensor Record can be regarded as a question that needs
to be answered by you.
The questions that you need to answer are generalized below:
What type of sensor do I have (analog, digital or serial)?
Analog Sensors
Do I need 12-bit accuracy or 18-bit accuracy?
What is the input and output voltage range of the sensor?
Digital Sensors
Do I need to measure a simple on-off state, count pulses or measure frequency?
If I am measuring frequency, what is the frequency range?
Serial Sensors
If the sensor is a serial sensor, is there a serial sensor type that directly supports it, or do I need to
write a General Serial Script
171
to retrieve its data?
What type of serial interface is required (RS232, RS485, TTL)?
What baud rate, parity, etc., does the sensor communicate with?
Where and how does the sensor need to be connected to the ZENO
®
-3200?
Do I want the sensor to be on at all times, or do I need to the ZENO
®
-3200 to control power to the
sensor in order to conserve power?
How frequently do I need to read data from the sensor?
How many times during the Sample Duration do I need to read data from the sensor?
Do I need any data conversion to be done within the Sensor Record?
