Analog& Digital I/O Sampling Rates
Sampling rates are in samples per second for a single analog channel or 8 bit digital I/O
port tested on Windows 2000 850 Mhz P3 with A/D clock running at full speed. Samples
per channel = Sample rate ÷ number of channels being sampled.
Modes of Operation:
The
SuperLogics
I/O modules can operate in three operation modes:
1) Polled
2) Asynchronous Update
3) Continuous Stream.
These modes of operation can be used singularly or together in combination.
#
1) Polled Mode
By far, the Polled Mode is the most common usage of the
ADC-1R2
Series
I/O
modules.
In this mode the Host computer sends a command to the I/O Modules which in turn sends
an associated response back to the Host computer.
#2) Asynchronous Update Mode
The I/O Module sends data
without
the Host sending a command to poll the I/O Module
in Asynchronous Update Mode.
NOTE:
Asynchronous Update Mode is configured using EEPROM locations 0x04/0x05.
