1
HV enable out -ve (differential with 2)
2
HV enable out +ve (differential with 1)
3
HV program out (0 to +2.048 V)
4
Analog gnd (reference for 3)
5
+5 VDC power out (200 mA max)
6
Digital gnd (reference for 5)
A differential pair programmable enable output is provided as a differential (RS-485 style) pair
on pins 1,2. This is typically used to gate off the multiplier for some external event by turning
off the high voltage.
+5 V power is provided to power a modular high voltage supply. These typically require 50 to
100 mA at 5V.
12.1.2 Test I/O
Four pin mini-DIN female. To mate with CUI MD-40, Conec 301A10479X or equivalent.

1
Test LED pulser output +ve (+5V)
2
Test LED pulser output rtn
3
PMT temperature sensor input (AD592 +ve)
4
PMT temperature sensor input (AD592 -ve)
The test pulser LED is returned to digital ground on pin 2 via 2 kohm and a switching transistor
controlled by the FPGA. For a typical LED the forward current in the on state will be 1.5 mA.
