jumper setting on the 1260-22 may be changed so that the effect
of an emergency reset is global. With the global reset
configuration, a reset signal propagates through the VXI Local Bus
to open all relays on all switch products that are connected to the
same Option-01T.
The local/global jumper on the 1260-22 printed circuit board
governs this option. The jumper is designated JP1 (see Figure 3-
3), and is a two pin shunt jumper similar to those used on disk
drives and personal computer boards. When open, only the relays
on the 1260-22 are opened in response to an emergency reset
condition (local reset). When jumpered, all relays on all boards
controlled by the same Option-01T are opened (global reset). The
1260-22 is shipped with JP1 in the open condition (local reset).
All 1260-Series and Adapt-a-Switch plug-ins respond to an
emergency reset condition when the scope is set to global. Certain
plug-ins and 1260-Series modules provide the front-panel contacts
for the external switch, and the circuitry to recognize a reset event.
A switch system may make full use of the emergency reset feature
if it includes at least one plug-in or 1260-Series module that has
reset recognition capability, such as the 1260-22.
