7.2 Connection of the F364 / F385-SEV module on the F353-ADC
card
The F364 / F385-SEV module houses the whole electronic circuit for the servovalve
management.
Its mounting on the F353-ADC card poses no problems, this can be easily made through
the two connectors J1 and J3.
The J3 connector is polarised (contacts 9 and 10 are not present) to prevent incorrect
mounting of the module.
