Digital Input and Output
The DI-148U and DI-148U-SP contain six software-programmable digital lines (bits) for input/output operations; the
DI-158 Series Instruments contain four. These lines provide an interface for the transfer of data between user memory
and a peripheral device connected to the instrument. Digital inputs can monitor alarms or sensors with TTL outputs,
while digital outputs can drive TTL inputs on control or measurement equipment. Remote control can be utilized with
bits 0 and 1 (for location see “Chapter 4. Connecting Input Signals”) using W

software. The digital I/O may be
enabled as Channel 9 using a DI-148U or Channel 5 using a DI-148U-SP or DI-158 model in W

Acquisition software can be used to record waveforms directly and continuously to disk while monitoring a
real time display of the waveforms on-screen. It operates and displays waveform signals in real time at the full sample
rate of the instrument being used. There are two versions of W
