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.
1 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.
2 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.

3 Serial Protocol
The USB port emulates an RS-232 connection, so the computer (controller) must
be set to the proper Com Port protocols when using the RJ-12 RS-232 port or the
USB port. The controller (computer) should be set to 8 bits, no parity, and 1 stop
bit. It must also be set to match the HDG-4000 baud rate, which can be selected
from 9600 baud to 230.4K baud in the OSD menu. Xon/Xoff flow control, or no
flow control for the RS-232 port can be selected in the OSD menu, and DTS/RTS,
Xon/Xoff, or no flow control can be selected for the USB port.
Note: It is often easier to start with a slow baud rate (e.g. 19200 baud) and no flow
control when initially setting up a connection. The high baud rates of the HDG-
4000 are primarily for use when adding new features through firmware updates.
Slower baud rates (e.g. 19200 or 9600 baud) are perfectly adequate in normal
use, and will permit very long connections (50-100 ft or more) over inexpensive 4-
wire telephone cables.
4 HDG-3000 Compatibility
Programs previously written for the HDG-3000 Video Generator may only support
9600 baud, which was the only baud rate available in the HDG-3000.
5 HDG-4000 Command Syntax
The HDG-4000 accepts ASCII text commands. Each command is 2 to 12
characters in length and must be followed by a carriage return (CR) character
(ASCII 13). You may not send multiple commands with a single CR. Partial
command strings are not valid.
Capital and non-capital characters are accepted, i.e. a = A, B= b.
All spaces and line feed (LF) characters are ignored.
6 Confirmation and Error Messages
The HDG-4000 will return “OK” (without quotes), followed by CRLF (ASCII 13,
ASCII 10), after executing each valid serial interface command.
If the HDG-4000 receives an unrecognized character string of 12 characters or
less it will return “ER “ followed by the unrecognized character string, followed by
CRLF. If more than 12 characters are received only the first 12 chars are returned
in the error message, and the remaining characters are discarded.
7 Query Commands
Query commands end with a question mark (?). Query commands return one or
more text strings (each 14 characters maximum), each followed by a CRLF. “OK”
followed by CRLF will be returned after the last text string.
To avoid a possible buffer overrun when sending multiple Query commands, wait
for the “OK” response before sending the next Query command.

8 Analog Embedded Sync & HV Sync Modes
The analog embedded Sync (BiLevel, TriLevel, or None) and HV sync (Pos, Neg,
or None) states are stored and automatically recalled when changing the Output
or Format modes. This is necessary because certain sync modes are required by
some video standards, but prohibited by others. For instance, embedded Bi-Level
sync is always required for the 480i or 480p formats when using YPbPr or YPbPrs
output modes, but embedded Bi-Level sync is not required for RGB or RGBs
output modes. Tri-Level sync is never permitted for 480i or 480p formats.
Hence, to conform to the various video standards, the sync modes must follow
several rules when the Format mode is changed between HD (720p/1080i/1080p)
and SD (480i/480p/576i/576p), or the Output mode is changed between
RGB/RGBs and YPbPr/YPbPrs. The generator stores 4 states for the (embedded)
Sync mode, and 4 states for the analog HV Sync mode, which each depend on
the current Output and Format modes.
Sync_Mode [Output] [Format] = Bi-Level, Tri-Level or None
HV_Mode [Output] [Format] = Pos, Neg or SoG (None)
where Output = YPbPr/YPbPrs or RGB/RGBs
Format = HD or SD
The HDG-4000 will recall the previous Embedded Sync and HV Sync states when
changing Format or Output, or you can send new Embedded Sync and HV Sync
modes after changing Format and/or Output. But don’t send a new Embedded
Sync or HV Sync mode before sending a new Format or Output mode, because
the Sync mode may be changed when the previous states are recalled.
