It's a standalone device. Well, aside from a terminal. :) That's
the main reason I love these Data I/O UniFamily programmers (UniSite,
2900, 3900, etc). Also, no PC-proprietary parallel ports...100%
standard RS232 serial I/O. You could run this thing from a PDP-11 if
you wanted to. Windows is persona non grata here, and I'm certainly
not going to depend on it for something critical to my work like
controlling a device programmer.
You just connect an ASCII ANSI terminal (I use a VT420) or a
computer running a terminal emulator and interact with it directly.
The user interface is very good, fast, and easy to use. If you
really want to, it does have a mode that you can set which makes it
communicate using a remote control protocol over the serial port, and
Data I/O has software for Windows which can control the unit via that
protocol.
The 2900 has a floppy drive from which it boots and loads
programming algorithms when you select a device. The later models,
including the UniSite, optionally have a hard drive which stores all
of that. My recently-acquired UniSite has a hard drive and two
floppy drives. They all read and write FAT-formatted floppies.
I really can't recommend them highly enough. I've used a bunch of
programming systems, and these are, by far, the best I've ever seen
in every regard.
