4.5.4 Supplies
The V1729 board uses the standard supplies of the VME : +/-12V and +5V.
It fabricates the –5V for the ECL logics starting from the +5V with the help of a DC-
DC converter capable of delivering 600mA.
The intensities consumed on these different supplies are :
+12 V
0.3A + X x Y x 0.7A
-12V
0.2A + X x Y x 0.7A
+5V
1.5A
where X is the rate of acquisition = relation of time spent awaiting the event / total time .
X is worth 1 in the case of infrequent event acquistions.
X is low (can fall to 1%) in the case of frequent events. In this case indeed, the dead time
for readout is dominant in relation to the time spent awaiting the event.
Y depends on the bandwidth mode:

GPIB Connector (HE10 26 points male)
Reference : J2.
1 : D1 2 : D5
3 : D2 4 : D6
5 : D3 6 : D7
7 : D4 8 : D8
9 : EOI 10 : REN
11 : DAV 12 : GND
13 : NRFD 14 : GND
15 : NDAC 16 : GND

19 : SRQ 20 : GND
21 : ATN 22 : GND
23 : GND 24 : GND
25 : NC 26 : NC
The corresponding HE10 female connector can be directly pressed on a 24 wire flat
cable equipped at the other extremity with a GPIB standard connector (CENTRONICS 24
points). Up to 18 HE10 female connectors can be mounted in parallel on the flat cable
(be careful then to only mount the bus polarization networks on only one of the boards).
JTAG connector
(HE10 10 pins male)
Reference : J8.
Permits the reconfiguration of the E2PROM (EPC2) from an Altera file « .pof » thanks to
JTAG.
