The +5 volt output allows you to power external TTL circuits if required.
The maximum current allowed from this supply is 1.0A
The +12 volt output allows you to power external circuits, charge a battery,
or power relays if required. The maximum current allowed from this supply
is 1.0A
This provides an input to the mainframe backplane for a +5V DC standby
power source. This may be from a separate battery or power supply. The
maximum current allowed is 1A total (pins 8 and 21 wired in parallel). It can
be used to power timers and other circuits when the mainframe is in standby
mode.
This pin provides an extension of the VXI backplane SYSRESET* signal
line. It can be used to monitor for SYSRESET* or to send a SYSRESET*
tot he backplane. Shorting this line to ground asserts the SYSRESET* signal
to the system. If you use an extension cable from the Diagnostic Connector,
make certain that you do not violate the VXI backplane electrical
specifications (i.e. keep the cable as short as possible, buffer the signal line,
etc.).
This pin lets you monitor the ACFAIL* signal from the VXI backplane. If
you use an extension cable from the Diagnostic Connector, make certain that
you do not violate the VXI backplane electrical specifications (i.e. keep the
cable as short as possible, buffer the signal line, etc.).
