Racal Instruments™
1255A
MATURE
Enhanced Optical and Microwave GPIB Switching
System
The Racal Instruments™ 1255A Switch System provides four slots for VXIbus
C-Sized 1260-Series switch modules. It contains all the necessary interfaces for
developing a comprehensive switch system, while significantly reducing cost with
the elimination of mainframes and controllers.
Key Features
Product Information
•tNon-Volatile Memory: stores relay
configurations for fast, easy setup
•t Maximizes switch density
GPIB and RS-232 Control
•t Reduces ATE switching cost
The 1255A comes complete with both an
internal IEEE-488 and RS-232 interface.
The included VXIplug&play compliant
drivers make it an easy addition to any
system. The 1255A additionally provides
a message-based interface that controls
multiple 1260-Series switch cards via the
VXI local bus.
•tPower-Up Recall: automatically recalls
a complete system configuration at
power-up
•t Four VXIbus C-sized switch card
capacity (1260 Series)
•t Built-in IEEE-488 and RS232
controllers
•t VXIplug&play compatible
•t Ideal for optical and microwave
switching systems
1260-Series Switch Family Compatibility
As with all 1260 Series switches, the local
bus is used to transmit control signals from
the internal controller to all 1260 cards in
the chassis.
The 1255A will support the entire line of
Racal Instruments switch modules with
signals from DC to light. The system also
provides an upgradeable path to a full
VXIbus system, if ever a larger ATE
system capability is needed.
Switch modules can be of mixed or dedicated signal type. An excellent selection
of 1x2, 1x4, 1x8, and 2x2 switches are
available.
•tRelay Monitoring: provides confidence
checking of all relays
•tScan Mode: provides synchronous
scanning of multiple test points
•tExternal Trigger: allows external device
to trigger switching operations
Easy Maintenance Features
You can maintain the 1255A with ease. A
pluggable power supply and easy-to-clean
fan filter simplify maintenance.
Accessories and Options
Rack mount ears and blanking plates
(3) are included with the chassis The
unit can be rack mounted with either the
annunciator panel or the switching modules
facing the front.
The 1255A is part of our extensive family
of VXIbus switching systems, which offers
modules in configurations ranging from
matrices to multiplexers, and signal type
from DC to Microwave.
Extensive Software Features
The 1255A includes powerful software
features such as:
•tSelf Test: executed automatically at
power-up; ensures that CPU, memory,
and switching module handshaking are
functioning correctly
