APPENDIX
The RS-232 Port
The TGP-5 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 TGP-5 software may be updat-
ed to refi ne operational details and to
include new features. Downloadable
updates will be posted on our website:
www.sunfi re.com.

Serial Cable
To connect the TGP-5 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 TGP-5 and normally 9-pin
female at the other, to fi t into your
computer's serial port (COM1 or
COM2).
Update Procedure
1. The current version level of the
software running your TGP-5
can be found by looking at the
Version Level OSD menu. This
is under the Software OSD
menu (see page 37).
2. Downloadable updates are on
our website www.sunfi re.com.
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
TGP-5. 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
TGP-5. Otherwise, you need
to disconnect the TGP-5 and
move it close to your computer.
5. Connect the TGP-5 RS-232
port to the corresponding serial
port on your computer.
6. Turn on the TGP-5 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 TGP-5 display will
show the status.
9. When the fi le transfer is com-
plete, press the Power switch
on the TGP-5 front panel. This
completes the upgrade.
10. Turn off your computer and the
TGP-5, and disconnect the se-
rial cable.
External Control
The RS-232 port also allows the
TGP-5 to be controlled externally by
Home Theater controllers and com-
put ers.
