Sunfire TGR-401-230 manual RS-232 Port

APPENDIX

The RS-232 Port

The TGR-401 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 TGR-401 software may be

updated to refine operational details and to include new features. Down- loadable updates will be posted on our website:www.sunfire.com.

The port can also connect to the se- rial port of a Home Theater Controller, to operate the TGR-401 remotely.

Serial Cable

To connect the TGR-401 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 fit into the TGR-401 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 TGR- 401 can be found by looking at the SOFTWARE VER. OSD menu. This is under the CON-

TROL menu (see page 35).

2.Downloadable updates are on our website www.sunfire.com. If the website file is newer than your current version, follow the website directions to update your TGR-401.

3.Record your calibration, preset stations or other settings. 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 TGR-401. Position them close enough so that they can be easily connected using your serial cable. If you have a laptop computer, then it may be easier to bring that close to the TGR-401.

5.Connect the TGR-401 RS-232 port to the corresponding serial port on your computer.

6.Turn on the TGR-401 and your computer.

7.Install the firmware update ap- plication to your PC.

8.When the file transfer is com- plete, press the Power switch on the TGR-401 front panel.

This completes the upgrade.

9.Turn off your computer and the TGR-401, and disconnect the serial cable.

External Control

The RS-232 port also allows the TGR-401 to be controlled externally by Home Theater controllers and com- puters.
