Introduction

The PICO ADC-100 and ADC-101 are medium speed analog to digital converters with two analog input

channels and programmable input voltage ranges. They can be used as a virtual instrument (oscilloscope,

spectrum analyser and meter) with the PicoScope program, or as a data logger using PicoLog.

Alternatively, you can use the ADC-100 driver software to develop your own programs to collect and

analyse data from the unit.

This manual describes the physical and electrical properties of the ADC-100 and ADC-101, and explains

how to use the Windows software drivers. For information about the software supplied with the unit,

please refer to the following documents:

PicoLog for Windows Online help file

DOS drivers ADC100.TXT file

PicoLog for DOS PL.TXT file

Connecting to the PC

The ADC-100 and ADC-101 can be connected to the PC in two ways:

• directly to a printer port on the computer

• to a USB port on the computer, via a PICO USB parallel port adapter.

Printer port operation

When you install the application software from the PICO CD, the computer will ask you which port to use.

You should select LPT1, LPT2 or LPT3.

To use the ADC, you should connect it to the printer port on your computer, either directly or using a good

quality extension cable.

USB port operation

Please note that USB printer port interfaces are not suitable for use with Pico products. If you wish to

connect a Pico product to a USB port, you will need a Pico USB Parallel Port adapter. You will also need

Windows 98, ME, 2000 or XP.

When you install the application software from the PICO CD:

• when the computer asks you which port to use, you should select USB-PP1

Once the USB driver software is installed, connect the Pico USB parallel port adapter to your PC: the

computer will automatically configure the drivers.

See Streaming for more information about the advanages of operating via a Pico USB parallel port.

Checking the installation

To check that the unit is working, start up the PicoScope program and then connect a voltage source to

the BNC connector. The ADC has the same connectors as an oscilloscope, so you can use standard

oscilloscope probes.
