HJT Model 100 User's Guide Appendix B-1
Appendix B—Configuration Data
Export / Import Procedures (Rev 1.0.0)
HJT Model 100 Projector Appendix B defines the steps to perform a Configuration Data
Export and Import from the projector to a host computer. The host computer can be any
system that has RS232 download and upload capability, including an IBM-PC
compatible, an Apple MacIntosh, or a UNIX system—the following procedures are for an
IBM-PC running the W
INDOWS
3.1 OS. We will use the W
INDOWS
T
ERMINAL
application
for communication with the projector. Other terminal emulation programs can be used
(i.e.: P
RO
C
OMM
) but all testing has been done with the T
ERMINAL
application.
Appendix B Note 1
The T
ERMINAL
application setup is the same as for controlling the projector via an
ANSI T
ERMINAL
(refer to HJT Model 100 Projector User’s Guide, Chapter 3)
Appendix B Note 2
Export/Import can be performed on either Port A or Port B. The Port must be
configured for ANSI T
ERMINAL
.
Port A speed is determined by Dip Switch #4 on the System Controller
board. O
N
is 9600 baud, O
FF
is 19200 Baud.
Port B can be configured for 2400, 9600 (default), or 19200 through the
C
OMM
S
ETUP
M
ENU
.
If both Port A and Port B are ANSI T
ERMINALS
, use Port A for Export/Import,
by setting Port A device = None, or Switcher, or Tethered Remote,
and set Port B Device = ANSI.
Remember to P

O
FF
(C

+ P) and HW R
ESET
(circuit breaker—on
rear panel) after changing any configuration parameters,
OR

press C

WARNING!
Your computer must have a 16550 UART
installed on the C
OMM
P
ORT TO
use 19200 Baud— use 9600 Baud if you
are not sure. An unbuffered 8550 UART will lose data during E
XPORT
,
which cannot be detected until a later I
MPORT
is attempted. With either
Baud, always use S
