SIS3820 scaler, 64 MB SDRAM, 32 inputs, TTL (50 Ohm), 100 MHz max. count rate, 4 control outputs, 4 control inputs.
The figures 53.1 and 53.2 show the configuration of the board: A32D32 at 0x38000000, rotary switches 3800 (VME connectors point right), VME adr. space 16 MB, 8 MB page, J 1 1000, J90 0101, JP 570 up. A second SIS3820 card has the adress 0x39000000.
The INHIBIT signal (50 Ohm, TTL) is fed into input 3 (control line 3), see figure 53.3.
Power requirements: 5V.
A SIS3820 board is introduced to Online by:
define/dev=counter/mod=sis3820/base=0x38000000/vector=0/chan=0 c1 .... define/dev=counter/mod=sis3820/base=0x38000000/vector=0/chan=31 c32
SIS3820/DGG2 test: Connect the 1 MHz clock output of a DGG2 ('CLK OUT') to input no. 1 of the SIS3820. Convert the NIM gate of the DGG2 to TTL and thereby invert the signal. Connect the NIM-TTL output with the control line 3 of the SIS3820.
If the board is used in a memory-mapped mode, using the mcs(), function, it has to be defined as a single device.
