Both DT9820 Series function modules share the following major
features:
• USB compatibility;
• Software configurable termination resistance for differential
analog inputs on a channel-by-channel basis.
• Software configurable 100 Hz analog input filters;
• Input gains of 1, 2, 4, 8, 16, 32, and 64;
• Continuously paced analog input operations;
• One 8-bit digital input port; high-to-low transitions on digital
input lines 0 to 3 can start A/D conversions on A/D subsystems
0 to 3; high-to-low transitions on digital input lines 4 to 7 can stop
A/D conversions on A/D subsystems 0 to 3;
• One 8-bit digital output port; digital outputs can drive external
solid-state relays; and
• Automatic software calibration of the analog I/O subsystems.
