The Basics

A logic analyser (analyzer) is used to probe digital signals in an electronic circuit. One example would be the input/output pins on a microprocessor such as an Arduino. The signals are displayed on a screen in the form of a timing diagram so that they can be compared against each other or against a timing reference.

Documentation

Manuals can be found here just search for LA3200.

According to this thread the pinout for the RS423 serial port on the back is:

2 - 3
3 - 2
4 *
5 - 5
6 *
7 - 8
8 - 7

The device is apparently identical to a Hitachi VC3120.

Pod photos and even a PCB design for replacement pods can be found here.
