Printer Port Instrument Installation
All DI-7xx Series instruments can use your computer's parallel (or printer) port to interface digital and analog signals
to your computer. Ethernet/USB models provide Ethernet or USB communication ports (cannot be used concurrently
with the printer port).
1. Plug the appropriate end of the supplied parallel communications cable to the 25-pin male connector labeled
PRINTER PORT on the rear panel of the DI-7xx Series instrument.
2. Connect the other end of this cable to your computer's parallel (printer) port. Note the LPT port number to which
you connected your device (LPT1, LPT2, etc.).
3. Set up your computer’s Printer Port operating mode. The parallel port may be set up in Standard, Bi-directional,
or EPP mode to communicate with your instrument. Choose a parallel port mode based on the desired sample
rate:
Parallel Port Mode Maximum Data Throughput*
