All DT9800 Series function modules share the following major
features:
• USB compatibility;
• Software configurable termination resistance for differential
inputs on a channel-by-channel basis.
• Input gains of 1, 2, 4, and 8 for all modules except the DT9805 and
DT9806, which support gains of 1, 10, 100, and 500;
• Continuously paced and triggered scan capability;
• A 32-location channel-gain list that supports sampling analog
input channels at the same or different gains in sequential or
random order;
• Internal and external clock sources for the analog input
subsystem;
• Digital TTL triggering for the analog input subsystem;
• One 8-bit digital input port and one 8-bit digital output port; the
digital input lines can be included as part of the analog input
channel-gain list to correlate the timing of analog and digital
events; digital outputs can drive external solid-state relays; and
• One dynamic digital output line;
• Two 16-bit user counter/timers programmable for event
counting, frequency measurement, rate generation (continuous
pulse output), one-shot, and repetitive-one shot pulse output
operations.
• Programmable gate types and pulse output types.
c. The gains provided on the DT9805 and DT9806 are 1, 10, 100, and 500. All other modules provide
gains of 1, 2, 4, and 8.
d. The DT9800-EC Series boards are nonisolated; the DT9800-EC-I Series boards and all other DT9800
Series boards are isolated.
e. The analog input range is 0 to 10 V or ±10 V.
f. The analog output range is 0 to 10 V, 0 to 5 V, ±10 V, or ±5 V.
g. The analog input range is ±10 V.
h. The analog output range is ±10 V.
