This section describes operations needed before powering up the board.
Please, refer to
Chapter 4 on page 10
for detailed information on board configuration and
jumper settings.
2.1 Jumper
settings
For the location and (default) settings of the various jumpers, please refer as follows:
1.
Close the jumper J51 to supply the board.
2.
Close jumpers J48-J50 to supply V
CC
.
3.
Close jumpers J23-J25
to supply 35V V
boost
to the board.
4.
Close jumpers J31-J33, J40-J41 and J43-J44 to supply 8V V
buck
to the board
5.
Close the jumper J46 to supply a soft start function to SPR internal regulator (C
slew
).
6.
Close jumpers J22, J26-J30, J34-J35, J37-J39, J42 and J45. These jumpers are only for
testing purpose and must always be closed.
7.
Close the jumper J36 to pull up the RST signal at power on.
8.
Close the jumper J14 to provide the clock signal to the Satellite/Deployment interface.
9.
Connect satellites for L9658 to pin 1 of jumpers J5-J8. If you want to simulate them, close
jumpers J5-J8 and provide the appropriate signals to the DICH1-DICH4 pins on the CPU
board connector.
10. Connect satellites for L9654 to pin 1 of jumpers J54-J55. If you want to simulate them,
close jumpers J54-J55 and provide the appropriate signals to the DICH5-DICH6 pins on
the CPU board connector.
11. Close the jumper J15 to enable deployment on L9654.
12. Close the jumper J21 to enable deployment on L9658.
13. Close the jumper J20 to provide the clock signal to the Arming interface.
14. Close the jumpers J13, J16, J17, J18, J19 to enable the squibs.
15. Connect squibs to connectors TP1, TP2 and TP7. If you want to simulate squib loads
instead of connecting them, close jumpers J1-J4, J9-J12, J52-J53 and J56-J57.
