Key Features
Figures 1-1
through
1-8
show the key features of the 1269.
Ease of Use
Plug-in Personality Module.
The orientation of the Plug-in
Personality Module allows either the
C0 slot
or
B0 slot
to
function as the mainframe
VXIbus Slot 0
location.
Fast Setup.
The 1269 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 1269 AC input is both auto-voltage and
auto-frequency ranging. The chassis does not require the configuration
of a voltage selection switch.
Enhanced Monitoring.
The 1269 optional micro-controller based
Enhanced Monitoring System (EMS) gives you key system health
status (Voltage, Airflow and Temperature). This option includes a
front panel alpha-numeric display, a fully VXIbus compliant message-
based interface, an auxiliary RS-232 port, and VXI
plug&play
drivers
and GUI.
Plug-in Power Supply, Fans, and Monitor.
The 1269 modular
system design results in a virtually wireless mainframe with low MTTR
and high MTBF. See
Figure 1-4.
Variable Extension Rack Mounting.
The adjustable rack mount ear
provides up to 1.50 (in 0.500 inch increments) extension rack mounting
capability. See
