FEM Power: 1. The TestBench version of the FEM requires A for proper operation. 2. The FEM can be powered from a 6U VME crate or from a lab power supply (using optional pigtail power leads).

Initial Conditions: 1. Text entered here will appear in the the top border of each sub menu 2. The FEM powers on in VME mode. Select USB mode to allow PC operation 3. Select the appropriate HIGH SPEED CHANNEL ENABLE(s) 4. Activate the RST (reset) button followed by the Auto Init button

Forced Data Read Setup: Use the register read/ write function to setup FEM registers Register 0x04 is used to mask/unmask the FastOR signals for chips Register 0x14 is used to mask/unmask the FastOR signals for chips Register 0x24 is used to mask/unmask the FastOR signals for chips Register 0x60 sets the maximum trigger rate 0x60 ~ 20 Hz., 0x40 ~ 40 Hz. Register 0x82 set to 0x01 enables the internal FastOR trigger Register 0x83 set to 0x01 disables the EXT_IN trigger

Write data to file Trigger rate Total number of events Optional stop after a certain # of events
