USB and RS-232 Serial Control Ports
The USB and RS-232 Serial Interfaces provide complete control of all HDG-4000
functions. Refer to the HDG-4000 User Manual for a description of all generator
functions and calibration patterns.
The HDG-4000 USB Control Port provides easy connectivity with the many
computers that no longer provide RS-232 connectors. The HDG-4000 USB port
emulates an RS-232 interface to provide easy compatibility with common PC or
Macintosh terminal programs such as HyperTerminal, and provides compatibility
with previous RS-232 based software written to control the AccuPel HDG-3000
Video Generator. RS-232 emulation also provides a serial control interface that is
easily accessible from software development tools for users that write their own
custom control programs.
The HDG-4000 RS-232 Control port provides backward compatibility with systems
that are already physically wired to support the AccuPel HDG-3000 Video
Generator's RJ-12 port. It also allows long connections (50-100 feet or more)
using inexpensive, standard 4-wire telephone cables in new installations.

USB Port - USB Driver

To use the HDG-4000 USB port you must first download and install a USB Driver
on your computer. The USB driver is available from the AccuPel website
(www.accupel.com). Full instructions for installing the driver are included with the
download. You may then connect the HDG-4000 to a computer using a USB
cable with Type A Male connectors on both ends.

RS-232 Port – RJ-12 Connector
No software driver is necessary to use the HDG-4000 RJ-12 port, but you will
need to configure an inexpensive ($1-$5) DB9 Female to RJ-12 (RJ-11) adapter.
A standard 4-wire telephone cable can then be used to connect the HDG-4000
RJ-12 port to the RS-232 serial port of a personal computer. Adapters that can be
configured without any soldering are available from many on-line sources, some
computer stores, and electronic parts suppliers such as Fry's.
The diagram shows the three wires to insert into the holes in the DB-9 connector
housing. Pin 1 is on the left side of the RJ-12 connector when facing the rear of
the HDG-4000, or when looking inside the adapter.
