Key Features
Figures 1-1
through
1-8
show the key features of the 1261B.
Ease of Use
·
Fast Setup.
The 1261B backplane uses active-automatic
VME interrupt acknowledge and bus grant daisy chaining.
Manual configuration of backplane switch settings or jumpers
has been eliminated.
·
Universal AC Input
.
The 1261B AC input is both auto-voltage
and auto-frequency ranging. The chassis does not require the
configuration of a voltage selection switch.
·
Visual System Health Status Indication.
The 1261B comes
standard with system monitoring that gives you key system
health status (Voltage, Current, Airflow and Temperature) on
the front panel display. Monitored parameters include
temperature rise on each slot, fan speed, power supply voltage
and currents.
·
Enhanced Monitoring.
The optional micro-controller based
Enhanced Monitoring System (EMS) adds a fully VXIbus
compliant message-based interface, an auxiliary RS-232 port,
and VXI
plug&play
drivers. The alpha-numeric display that
comes with the EMS provides detailed system status
messages.
·
Plug-in Power Supply, Fans, and Monitor.
The 1261B
modular system design results in a virtually wireless mainframe
with low MTTR and high MTBF. See
Figure 1-3.
