Transformer and Direct Coupling
The module can be configured to work either in the transformer- coupled mode or in the direct-coupled mode. Jumpers are provided on the modules to select the mode. It is configured to work in Transformer coupled mode by default.
The ARINC717 device from the Holt Integrated circuit includes a selectable Harvard Bi-Phase (HBP) or Bi-Polar Return-to-Zero (BPRZ) receive channel and transmit channels with HBP and BPRZ encoders and line drivers. The receive channel has integrated analog line receivers and the transmit channels have integrated line drivers for the corresponding encoding method (HBP and BPRZ). The part operates from a single +3.3V. Each transmit and receive channel has a 32-word by 12-bit FIFO for data buffering. The device uses an SPI (Serial Peripheral Interface) for host access to internal registers and data FIFOs.
The software includes Drivers and APIs. The module comes with a powerful set of library functions to access the entire MIL-STD-1553B and ARINC717 functionality. Source code is provided for samples, and detailed documentation. The drivers are designed in a modular fashion consisting of component functions & application functions. The user’s test program can be developed with few calls to the driver, by using the set of Application functions provided. Driver and high-level API libraries for Windows XP, Windows 7 and Linux are available.
