The RS-232 Port

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.

Communications

Serial RS-232, 9600 Baud, 8-N-1

DB-9 Wiring

PINS 1, 6 and 4 are joined together internally

PINS 7 and 8 are joined together internally

PIN 2- Data from processor to controller (processor transmit)

PIN 3- Data from controller to processor (processor receive)

PIN 5- Ground/Common

PIN 9- No connection

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 connector 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 available from most computer stores (or from Radio Shack as # 26-117). It should be 9-pin male at one end, to

fit into the TGIII and normally 9-pin female at the other, to fit into your computer's serial port (COM1 or COM2).

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.

External Control

The RS-232 port also allows the TGIII to be controlled externally by Home Theater controllers and comput ers.

Note that all standard commands and extended data are echoed back to the sender. When a change is made locally, the data is broadcast, except for the case of “Toggle” and volume commands.
