A-D converter types

Several types of external (serial interface) A-D converters can be used with LabHelper.   In addition, it can read streamed serial data from instruments that provide serial data output (but only one such instrument at a time can be connected).   The supported A-D devices are described at these links:

A-D converters:

Note for all A-D converters:   Modern Macs lack built-in serial ports, so for all A-D converters but the Sable UI3, you'll need a USB to serial converter and driver software (and you may need the latter for the UI3).    The units made by Keyspan (now, TrippLite), specifically the USA-19HS, function reliably with LabHelper.   Other brands have not worked well, or at all.
