The KAD/DAC/001 can be used to output up to eight single-ended waveforms, and provide up to 16 discrete output indications.
Features
- Eight single-ended (S/E) analog output channels (±10V)
- 0.25% (FSR) total error from all sources for analog output
- Lookup tables to map input parameter to analog output
- 16 S/E discrete output channel (Buffered TTL)
- Combinatorial logic can be used to map multiple parameters to a single discrete output
- Outputs are short-circuit protected (indefinite to ground)
Applications
- Output a voltage waveform based on backplane parameters, for example for a strip recorder
- Provide discrete outputs based on backplane parameters, for example memory status
The NET/SWI/101 is an 8-port airborne Ethernet switch designed for operating in harsh environments. Each port is configurable for 10BaseT, 100BaseTX, and 1000BaseT link speeds or auto-negotiate over copper wiring, supporting straight-through or cross-over cables.
The KAM/CHS/13U is a thirteen user-slot Acra KAM-500 chassis that includes a power supply module that regulates power supplies for the backplane.
DAS Studio 3 software allows you to configure DAUs, network switches, recorders & ground stations in an integrated environment.
KAD/DSI/102 monitors the status of up to 24 differential ended discrete input channels. Each of these has an assigned programmable 32-bit counter.
The KAD/VID/106 is an H.264 video encoder card that converts one of three composite analog video inputs.
The KAD/MAT/101 allows you to run your own programs based on a dual-core C6000DSP+ARM9 microcontroller. It provides high-performance DSP functions.
KAD/ADC/136 is used to condition & digitize up to 8 analog channels.
KAD/DAC/001 8 Channel Digital Module
The KAD/DAC/001 can be used to output up to eight single-ended waveforms, and provide up to 16 discrete output indications.
The module is able to take any parameter from the backplane and, using a user-defined lookup table, map that parameter to the output voltage range of the analog output channel. A different map can be used for each of the eight analog channels.
Each of the discrete outputs can be set to a logic high or low based on a combination of input words. The input words are passed through a user-defined mapping function, which produces a single bit output. A typical example would be a max-min. window function to determine if a parameter lies in a defined range.
The outputs from the mapping functions can be either logically ANDed or ORed together, and inverted if required, in order to control the discrete output.
Aerospace Instrumentation Brochure
Modern aerospace instrumentation systems can be highly complex, and it can be difficult to know how to meet program needs. It’s not unusual for requirements to change during a campaign and cause significant delays, and data must be captured reliably no matter what – otherwise expensive additional flights will be needed or months of program data could be lost. Read our brochure to learn how you can reduce your risk with commercial off-the-shelf (COTS) solutions.
