EADS North America Test and Services Racal Instruments™ 1260-114 High-Density Digital I/O Plug-in The Racal Instruments™ 1260-114 is a 96-channel digital I/O plug-in for the Adapt-a-Switch™ platform. A 48-channel high voltage/current open-collector version is also available. The 1260-114 installs easily and directly from the front panel into the Racal Instruments™1260-100 Adapt-a-Switch™ VXIbus carrier. Please refer to the 1260-100 data sheet for specifications and product features. Product Information Key Features • 96 TTL, CMOS, or open-collector input/output channels or 48 highvoltage/current open-collector input/output channels • 2-wire programmable handshaking • 200 kHz data rate • Drives up to 50 V and sinks up to 1.5 A per channel • Synchronous, asynchronous and mixed operating modes • Standard Adapt-a-Switch™ plug-in design for ease of replacement The 1260-114 is available in TTL, CMOS, OC (standard open collector) or HVOC (high voltage/current open collector) I/O channels. Each TTL or CMOS I/O channel may be placed in a high-impedance, tristate mode. Additionally, the CMOS version features TTL level compliance, provided the maximum current of the driver is not exceeded (refer to the specifications). The high channel count of the digital I/O plug-ins allows a significant portion of digital I/O to be realized in a single slot of the Adapt-a-Switch™ carrier, saving valuable VXIbus chassis space. The 1260114 provides 96 digital I/O channels in twelve groups of eight bits each. The 1260-114OC version can utilize a separate external pull-up supply for up to 32 VDC for each independent group, and the 1260-114 HVOC can utilize a separate external pull-up supply for up to 50 VDC. The versions are ideal for controlling external digital circuitry, switches, relays and similar devices. Each channel is configurable as an input or an output and can be individually controlled in asynchronous mode or with other channels in synchronous mode. The 1260-114 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 1260-114 is programmable in several operating modes and data may be manipulated in either hex, decimal or binary. Memory is available on the Racal Instruments™ Option-01T switch system controller to allow 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™. Please refer to the Option 01T data sheet for additional product features. Block Diagram ECO# 2010-EADSTS-12-13-24-MU. Uncontrolled Unclassified Information (“UUI”).
