Digital I/O
The digital I/O port of the instrument can control external circuitry (such as a component handler for
binning operations).
The I/O port has 14 lines. Each line can be at TTL logic state 1 (high) or 0 (low). See the pinout
diagram in Digital I/O port
(on page 3-80) for additional information.
There are commands to read and write to each individual bit, and commands to read and write to the
entire port.
