NEXSYS LYNK – Integrated Signal Processor
NEXSYS LYNK: integrated signal processor that combines control, power, and communication in a single intelligent module.
The DCU120 is a highly configurable Integrated Signal Processor (ISP) based on a wide range of inputs and outputs and an application-specific Configuration File (CF).
The DCU120 includes the following Inputs/Outputs (I/O) common to all form factors: 1) ARINC 429 Transceiver (2 Bus In / 1 Bus Out), 2) RS232 Transceiver, 3) Discrete Input and Outputs, 4) Analog Inputs, and 5) an internal health monitor output. The number of Discrete Inputs and Outputs varies by form factor and configuration specifics.
Additionally, the DCU120-S can be configured to provide HMI by specifying a momentary action switch (acts as an additional Discrete Input to the microprocessor) and an illuminated cap that provides visual feedback to the operator. Momentary switch can be programmed to act as an alternate action switch.
The Configuration File is what defines the relationship between the inputs and the outputs. Each Configuration File development begins with a detailed capture of specific customer requirements. In addition to processing, specific operations that can be included in the CF Include:
- ARINC 429 → Discrete
- Discrete ←→ RS232
- Analog → Discrete/ARINC 429 (ADC)
- Boolean Logic Dynamic Comparisons (<, >, =)
- Timer Functions
- Complex Math
- Floating Point Math
- State Machine
SilverLine® Test Cables are cost-effective, durable, high-performance cable assemblies designed for use in a broad range of test and interconnect applications. Fabricated from rugged, solid PTFE dielectric cable with stainless steel connectors and a proven strain relief system, these cables provide long life and excellent stability in applications where they are repeatedly flexed and mated/unmated. SilverLine test cables are ideal for use in production and field and laboratory test environments. They are also economical enough to be used as interconnects in test systems.
