Using Head Firmware 1.01F with Version 3.50.05/3.50.07

The following problem can occur with certain TH2 heads that are currently in the field or in the integration line:
The data line that carries packets that include the Write Laser temperature set point from VER D T2HC to Ver D WLPB are susceptible to noise. This can cause the laser temperature to be set to an erroneous value.
The problem can occur when using firmware version 1.01e or earlier. The MCE firmware does not notify the head that the shutter will open in order for the head to stop monitoring laser power. Therefore, the head powermonitor mode must be turned off. This mode did not exist in firmware versions prior to, and including, the 1.01 series. In upgrades to series 1.01, Off is the default.

Head firmware 1.01F solves this problem. Since the firmware was checked only as part of the 3.51.02 Quantum package, in order to use these (known) defective heads with Quantum versions prior to 3.51.02 (3.50.05 and 3.50.07), load only the new head firmware, change a certain head parameter (only once) and continue to use the regular version safely.

Loading Head Firmware 1.01F (attached below in zip format):

1. Copy the file th2h101f.bin to the machine's C:\th2\tools directory.
2. Close the Lotem application.
3. Open SPlot.
4. Type: QUANTUM>> set head type 3
5. Type: QUANTUM>> head program
6. Type: QUANTUM>> head boot
   and wait for percentage completion.
7. Close Splot.
8. Open a DOS prompt.
9. Type: C:\th2\tools\ tehload p=8 th2h101f.bin
   and wait for percentage completion.
10. Open SPlot.
11. Type: QUANTUM>> reset

Turning Head Power Monitor Mode Off:

1. Open SPlot .
2. Type: QUANTUM>> th2 "eng"
3. Type: QUANTUM>> th2 "set sys powermonitor false"
4. Type: QUANTUM>> th2 "set sys" and verify that the powermonitor line appears as follows:
   [03510] SYS powermonitor False True
