The input signals are supplied via the 9-pin "IN 1..9" connector and routed to
the piggyback. From there, they are led back through connector "OUT 1..15" -
once they have been processed. There are also eight LEDs on the front panel
which can be addressed by the piggyback.
Up to four DC/DC converters can be installed on the ES1652.2 Carrier Board to
power the piggyback. These can be supplied with 5 V or +12 V from the
VMEbus backplane.
There are three fuses on the carrier board that provide protection against volt-
ages from the backplane.
CAUTION!
There is no protective circuit on the ES1652.2 Carrier Board for the
inputs and outputs! If required, this must be ensured by the customer
on the relevant piggyback.
