Firmware Loading
12.0 Firmware Loading
The following items are required in order to load the firmware onto a panel:
• PC with a serial port
• Serial Cable
• QX-5000N RS-232 Debug Tool
• HyperTerminal
Before loading a new firmware onto the panel ensure that the PC being used has
HyperTerminal installed. Firmware needs to be individually loaded onto each board that
contains a CPU: the main board, the audio card, the quad-loop adder and the RAXN-LCD.
Refer to Appendix A: Hardware Changes for information about changes in component
positions from Flex-net Phase I.
12.1 Main Board Firmware
1. Connect the serial cable from the PC directly to the main board.
2. Run the HyperTerminal software on the PC.
3. In the HyperTerminal start up prompt set the correct communications port and select a
baud rate of 115200.
4. Reset the processor on the main board by shorting the reset jumper. The jumper only
needs to be shorted momentarily, it should be normally open. During the reset process
press any key in HyperTerminal to enter the Flex-Net shell.
5. Input the following set of commands after the "flexnet>" prompt appears and press enter
after each one: "sf probe 1", "sf erase 0x200000 0x600000", and "run sflash".
6. Navigate to the HyperTerminal menu bar and select Transfer, then select Send File. A
Send File window appears.
7. Specify the location of the binary file that contains the new main board firmware by
entering the file path or by pressing the Browse button and searching for the file. Set the
Protocol to "Ymodem" and press Send.
8. When the "flexnet>" prompt reappears type in "reset" and press enter.
12.2 Audio Card Firmware
1. Connect the serial cable from the PC to the QX-5000N RS-232 Debug Tool and connect
the 8-pin head to the P4 RS-232 Debug port on the audio card. Ensure that the keyed
extrusion on the connector lines up with the one on the port.
2. Run the HyperTerminal software on the PC.
3. In the HyperTerminal start up prompt set the correct communications port and select a
baud rate of 115200.
4. Reset the processor on the audio card by shorting the reset jumper, JW4. The JW4
jumper is the closest one to the 8-pin port and only needs to be shorted momentarily, it
should be normally open. During the reset process press any key in HyperTerminal to
enter the Flex-Net shell.
5. Input the following set of commands after the "flexnet>" prompt appears and press enter
after each one: "sf probe 1", "sf erase 0x200000 0x600000", and "run sflash".
