INTRODUCTION
   This Users Manual provides a more detailed description of the evaluation board and demo program than
in the Quick Start Guide.The Holt HI‐3593 ARINC 429 Evaluation Board can be used to evaluate 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. The main board “General Purpose SPI Evaluation Board” includes switches, pushbutton switches and LEDs to help navigate the operating modes and confirm data and status information. A Freescale MC9S12XDT512 microcontroller on the main board communicates with the HI‐3593 through the SPI interface. A Serial UART port is provided which enables viewing messages and status information or entering of optional commands using any terminal program such as Hyper‐Terminal. The HI‐3593 Evaluation Board is a daughter card that plugs on to the General Purpose SPI board via two 26 pin connectors.
