Racal Instruments™
1260-700
Prototyping I/O Plug-in
The Racal Instruments™ 1260-700 is a prototyping plug-in with 88 digital I/O
lines for the Adapt-a-Switch™ platform. The 1260-700 installs easily into the
Racal Instruments™1260-100 Adapt-a-Switch™ VXIbus carrier or the Racal
Instruments™ 1256 GPIB switching mainframe. Please refer to the 1260-100
or 1256 data sheet for specifications and product features.
Key Features
•t 88 TTL I/O lines usable as either
digital inputs or outputs
•t Two-piece “open architecture”
design allows the creation of user
plug-ins
•t Prototyping kit allows breadboarding of custom designs
•t 200 kHz VXI data rate
•t Synchronous, asynchronous and
mixed operating modes with 2-wire
programmable handshaking
•t Adapt-a-Switch™ plug-in design
for VXIbus or GPIB operation
Product Information
The 1260-700 uses a modular approach
to achieve maximum flexibility for the
1260-100 VXIbus Carrier or 1256 Switching
Mainframe user. The 1260-700 includes
a connectorized interface section that
provides connection to the Adapt-aSwitch™ platform and 88 channels of
bi-directional digital I/O plus +5 VDC power
protected by a self-healing fuse.
When installed in a 1260-100 VXIbus
carrier, the 1260-700 also has fused +12
V and +24 V available. Also included is a
prototyping kit, which includes a prototyping
card with 0.1 x 0.1 inch prototyping grid,
a connector to the interface section, and
blank panel hardware.
The prototyping grid has a ground bus
and two uncommitted buses which may
be jumpered to an internal or external
power supply. The 1260-700 uses an
open-architecture design. The pinout of
the 1260-700 interface section and layout
of the “user-defined” section is provided
so that custom plug-in boards may be
designed.
Each 8-bit digital I/O port is configurable
as an input or an output and can be
individually controlled in asynchronous
mode or in synchronous mode.
The 1260-700’s digital I/O has a two-wire
handshake mode available for the control
of synchronous I/O transactions. Each
handshake line can be programmed as
either active high or active low providing
a flexible interface with user signals.
The 1260-700 is programmable in
several operating modes and data may
be manipulated in either hex, decimal
or binary. Memory is available on the
1260-100 VXI Carrier or 1256 Mainframe
allowing buffered I/O operations.
The Adapt-a-Switch™ series includes
VXIplug&play support for frameworks
based on Microsoft Win32® application
programming interface, including drivers for
LabWindows™/CVI and LabVIEW™.
For example, a user-defined custom switch
card, Analog to Digital Converter (ADC)
card, or Digital to Analog Converter (DAC)
card may be substituted for the prototyping
area.
The blank front panel may be punched
by the user to create a custom connector
interface. As an option, the 1260-700 may
be ordered with front panel cutouts for
either a 64 or a 160 pin right angle DIN
connector.
