Replacing a TMCE Board

When you replace a TMCE board, you must save all the relevant parameters of the platesetter and load the new board with the right firmware version. The following procedure describes how to replace a TMCE board.

Procedure

The Replacing the TMCE Board procedure includes the following steps:

• Saving NVS parameters
• Replacing the TMCE board
• Loading the firmware
• Restoring NVS parameters to the TMCE board
  
  

Saving NVS parameters

Before you replace the TMCE board, you must save the NVS parameters from the current TMCE board to the disk.

Note: The files must be saved under the same directory of the bload program.

1. Open Splot Quantum>>fw dir and write down all the firmware versions that are listed.
   
2. Check the file name you need to enter by accessing c:/ th2 /tools to see the latest file that was saved.
3. Quit the terminal (Splot) to free the serial port.
4. Open a Dos prompt on the PC controller and type the following commands:

• Save the Ram from the Turbo TMCE to the Disk
  C:\Th2\tools\ bload f=File name_ram.bin p=8 d=ram i=nvs upload
  For ex: QuantumRam.bin
  Verify that it is saved successfully.
  
• Save the Flash from the Turbo TMCE to the Disk
  C:\Th2\tools\ bload f=File name_flash.bin p=8 d=flash i=nvs upload
  For ex: QuantumFlash.bin
  Verify that it is saved successfully.
  

Notes:

• Naming the files - You can give any name to the NVS files (both Ram & Flash), as long as it has the extension .bin. Record the file name in order to restore it to the new board. It is recommended to give a <date>.bin name so that you will have a reference.
• f = represents the file that you load. The name may be changed by another service engineer.
• If the save operation fails, delete the file that was created and repeat the save procedure.
• If the save operation fails, check spelling. If it fails continuously, reduce the baudrate as follows:
  At the Splot prompt, type Quantum>>mce Baud 9600 then go to: Term/PortSetting and enter the following parameters:
  Baudrate: 9600
  Parity: none
  Data bits: 8
  Stop bits: 1

  Repeat step 2 to save. Then go to term/Port Setting and return the baudrate to 57600.
  

Replacing the TMCE Board

1. Open the top front door.
2. Open the left side door.
3. Disassemble the Distribution Box Mech panel.
4. Remove the two screws on the electronic tray to provide easy access, and slide the tray half way out.
5. Disconnect the cables one by one.
6. Remove the four Philips screws that connect the TMCE board to the tray, and remove the TMCE board.
7. Assemble the new TMCE board. Be sure to connect all the cables correctly. Use drawing 1 as a reference.
   
   

Drawing 1: TMCE Connection



Note: The TSP connector on the TMCE board has the same size and shape as the connector for the scsi cable. Do not confuse them.

8. Turn on the platesetter, and start the Lotem application and the Splot.
   
9. Type Quantum>> fw dir
   A list of all the firmware loaded on the board appears.
10. Check that the files are compatible to step 2 in the Saving NVS Parameters section. If they are not compatible, continue loading firmware.
    

Loading the Firmware

1. Type Quantum>> Reset boot
   A Boot>> prompt appears.
   
2. Quit the terminal (Splot) to free the serial port.
   
3. Open a Dos prompt and find the file name for the correct Xilinx firmware.
   Then load it by typing the following:
   
• C:\Th2\tools\ bload f=File name.bin p=8 i=Lca
  For ex: mcelca0101.bin
  Wait until it finishes loading successfully.
  
4. Find the file name for the correct TMCE firmware and load it by typing the following:
   
• C:\Th2\tools\ bload f=File name.bin p=8 i=main
  For ex: QuantumFmwRelease106.bin
  Wait till it finishes loading successfully.
  
5. Start Splot.
   
6. Type Quantum>> reset
   
7. Type Quantum>> scan eh_&Logicpower bon
8. Type Quantum>> reset
   

Restoring the Parameters to the TMCE Board

It is very important to reload the parameters that were saved in step 4.

1. Quit the terminal (Splot) to free the serial port.
2. Open a Dos prompt:
   C:\WINDOWS >cd\
   C:\>cd th2\tools
   C:\Th2\tools\ bload f=file name_ram.bin p=8 d=ram i=nvs
   C:\Th2\tools\ bload f=file name_flash.bin p=8 d=flash i=nvs
   
3. Type Quantum>> reset
   Note: The file must be created with the version of firmware that is being loaded.
4. Close all machine panels and covers.
5. Expose and check that the image is clear of artefacts.
