Sunfire Radio manual RS-232 Port

APPENDIX

The RS-232 Port

The Receiver 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 software may be updated to reÞne operational details and to include new features. Downloadable updates will be posted on our website: www.sunÞre.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 to-

gether 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 Receiver's RS-232 port to a computer, you will need a "straight-through" serial cable. This has connector pins at one end con- nected directly to the pins of the con- nector 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 Þt into the Receiver and normally 9-pin female at the other, to Þt into your computer's serial port (COM1 or COM2).

Update Procedure

1.The current version level of the software running your Receiver 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 Þle is newer than your current version, follow the website directions and down- load the new Þle 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 Receiver. 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 Receiver. Otherwise, you need to disconnect the Receiver and move it close to your computer.

5.Connect the Receiver's RS- 232 port to the corresponding serial port on your computer.

6.Turn on the Receiver and your computer.

7.Find the Þle 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 Þle. The Receiver's display will show the status.

9.When the Þle transfer is com- plete, press the Power switch on the Receiver's front panel. This completes the upgrade.

10.Turn off your computer and the Receiver, and disconnect the serial cable.

External Control

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