The TGIII has a rear panel
RS-232 Serial communication port.
This allows the FLASH memory to
be upgraded to the latest software by
connecting to a PC.
The TGIII software may be updated
to refi ne operational details and to
include new features. Downloadable
updates will be posted on our website:
www.sunfi re.com.

The RS-232 connector is female.
Serial Cable
To connect the TGIII port to a
computer, you will need a "straight-
through" serial cable. This has con-
nector pins at one end connected
directly to the pins of the connector at
the other end. For example, pin 1 at
one end connects to pin 1 at the other
end, pin 2 connects to pin 2, pin 3 to
pin 3 and so on.
These common cables are avail-
able from most computer stores (or
from Radio Shack as # 26-117). It
should be 9-pin male at one end, to
fi t into the TGIII and normally 9-pin
female at the other, to fi t into your
computer's serial port (COM1 or
COM2).
External Control
The RS-232 port also allows the
TGIII to be controlled externally by
Home Theater controllers and com-
put ers.
The following information is for
programmers and developers:
Partial Serial command set
Note that all stan dard com mands
and ex tend ed data are echoed back to
the sender. When a change is made
locally, the data is broad cast, except
for the case of “Toggle” and volume
commands. Here is a list of the most
popular commands. (Contact Sunfi re
Technical Support, or our website
www.sunfi re.com for a more extensive
list of commands).
Update Procedure
1. The current version level of the
software running your TGIII
can be found by looking at the
Version Level OSD menu. This
is under the Software OSD
menu (see page 37).
2. If the website fi le is newer than
your current version, follow the
website directions and down-
load the new fi le onto your
computer's hard drive.
3. Record your calibration, preset
stations or other settings on
page 57. In most cases, the
upgrade will not affect any of
these settings, but it is good to
record them just in case.
4. Turn off your computer and
the TGIII. Position them close
enough so that they can be
easily connected using your
serial cable. If you have a lap-
top computer, then it may be
easier to bring that close to the
TGIII. Otherwise, you need to
disconnect the TGIII and move
it close to your computer.
5. Connect the TGIII RS-232 port
to the corresponding serial port
on your computer.
6. Turn on the TGIII and your
computer.
7. Find the fi le you downloaded in
step 2, and run the program.
8. In AUTO mode, the software
will look for an active serial
connection and upload the new
fi le. The TGIII display will show
the status.
9. When the fi le transfer is com-
plete, press the Power switch
on the TGIII front panel. This
completes the upgrade.
10. Turn off your computer and the
TGIII and disconnect the serial
cable.
