Connected to a computer, the SIA-IIIR receives ASCII characters sent from the RS-232 port and translates them into the pulse format recognizable to the SR-compatible component. This means that any SR-compatible Pioneer component can be controlled from the computer.
The article mentions that it was adapted from the Macintosh:

This device was originally conceived by Visual Database Systems for use with Macintosh computers, since many LaserDisc software companies have focused their development on Apple's systems.
I believe a description for the Apple II might be:

Visual Database Systems manufactures such a device: the SIA III
Serial Interface Adapter. Visual Database Systems is primarily a devel-
opment house and is not prepared to do end user support for the
consumer market. Instead. they generally sell the SIA III to companies
like Voyager with the expectation that the company they supply will
create and support a product for the consumer market using the
device. Voyager sells the interface with Macintosh software as The
Box ($149.95) to allow their Criterion HyperCard stacks to be used
with various consumer-level players.
But this is so old and pre-Internet that I can't find a picture of the actual SIA III device!
