ADC-20/ADC-24 terminal board

For easy connection to the DB25 connector, we recommend that you use the ADC-

20/ADC-24 terminal board, part number PP310. This has screw terminals to allow

you to connect wires to all of the data logger's inputs and outputs without soldering.

It also has space for voltage-divider resistors, a temperature sensor and a quad op-

amp.

LED

The ADC-20 and ADC-24 have an LED, next to the entry point of the USB cable, that

you can use to verify that the unit is working. The LED flashes whenever the unit is

taking readings. It also flashes briefly during "enumeration", the process that PicoLog

uses to detect all Pico USB devices plugged in to the computer.
