Digital I/O / DA4 Overview
Background
The digital I/O /DA4 port contains up to 3 modes:
External Remote Control, DA4 Output Function and
User-defined output function, which is divided into User
Mode and 4094 Mode individually.
Use the external I/O connector on the rear panel to
control the instrument remotely and produce D/A
output.
By providing separate VCC power for the terminal, the
outputs can also be used as a power source for TTL
and CMOS circuits.
