The local reset is triggered when the connection between the two pins is inter-
rupted. The pins, however, have to be supplied with 5 V < VCC < 48 V. The
reset only affects the piggybacks and
not
the VMEbus.
If you use more than one ES1650.1 Piggyback Carrier Board in a system and
wish to use a common local reset for all boards, you can connect the corre-
sponding pins of the boards in series with the relays.
Fig. 1-4
Local Reset for Several Carrier Boards
A jumper can be used to disable the function of the two front panel pins so
that an external local reset cannot be triggered.
note
If pins 9 and 42 of the front-facing connector X1 remain disconnected and the
external reset was triggered by jumper B20, there can be a sporadic reset of the
piggybacks.
Connect pins 1 and 2 of jumper B20 if you are not using the external reset and
leave pins 9 and 42 disconnected.
