INTRODUCTION
   The Holt HI‐3593 ARINC 429 Evaluation Board demonstrates most of the features of the HI‐3593 ARINC Dual Receiver and Single Transmitter IC. The HI‐3593 features an on‐chip DC‐DC converter which generates both +5V and ‐5V to supply the bipolar differential voltage levels needed to meet the ARINC 429 Bus levels from a single 3.3V supply voltage. A Freescale MC9S12XDT512 microcontroller communicates with the HI‐3593 through the SPI interface. The main board “General Purpose SPI Evaluation Board” includes switches and LEDs to help navigate the operating modes and confirm data and status information. A Serial UART port allows debug and data messages to be sent to a PC using any terminal program such as HyperTerminal. The HI‐3593 Evaluation Board is a daughter card that plugs on to the General Purpose SPI board via two 26 pin connectors.

   This guide summarizes how to get set up and running quickly. Additional support material and software are provided in the included CD‐ROM.
