Pulse Stream Output Using Timers
The boards allow the generation of output pulses based upon a programmable setting. These output timers
can be set at any time regardless of the state of any synchronous or asynchronous operations which are
currently taking place on other channels.
Analog Output Channels
The boards that have analog output capabilities have the ability to output analog data to any of the available
(up to four) D/A channels. Each D/A channel may be asynchronously updated by an application if the D/A
channel is not currently being used for waveform output operations.
Counter Input Channels
With exception of DaqBoard/2003 and /2003c, the boards have counter input capabilities and have the
ability to read counter input [if the counter channel is not configured for synchronous acquisition]. As in the
case of synchronous operations the 4 16-bit counter input channels can be used individually or cascaded
into 2 32-bit counter channels. For either cascaded or non-cascaded counter channels each channel can be
configured for:
• Clear on Read Mode - specifies that each counter should be cleared (reset to 0) upon being read.
• Continuous Totalize Mode – specifies that each counter is to free-run and not be cleared during
the read operation.
