HI-3717 Evaluation Board
Quick Start Guide
Introduction:
The Holt HI-3717 Evaluation Board demonstrates most of the features of the HI-3717 ARINC 717
Protocol IC. ARINC 717 is a communication protocol used between the Digital Flight Data Acquisition
Unit (DFDAU) and the Digital Flight Data Recorder (DFDR) used on commercial aircraft.
This guide demonstrates how to get set up and running quickly. Additional support material and
software are provided in the included CD-ROM. Since the demo code is programmed into the
microcontroller flash, the demo is operational right out of the box. No software development tools are
needed to run the demo.

Demonstration Board Set Up
1. Connect a +3.3V power supply to TP1 and ground to TP6. This is the only power supply
needed since the HI-3717 includes an on-chip DC-DC converter which generates +5V and -5V
to meet the ARINC transmit levels.
2. Connect the included RS-232 cable to the board and the PC Serial (COM) port. To view
ARINC messages, Control and Status registers and enter optional commands, a terminal
program such as Windows HyperTerminal may be used. Configure communication for
115200 Baud, 8 bits, No Parity, No handshaking.
3. HI-3717 daughter card default jumper settings:
J1 - shorted J4 - open
J7 - shorted J5 - open

Board RESET
A RESET pushbutton is provided. A DIP switch is also provided to continuously assert processor RESET.
For normal operation ensure SW2 – 4 (MRST) is in the open position, otherwise the MCU is held in the
reset state.
Main Board Jumpers
Some jumpers do not apply to the HI-3717 so they will typically be shown as NA.
JP1 - NA, JP2 - NA
JP3 - VDD jumper to J5 VLOGIC. Remove JP3 to measure ICC.
JP4 - NA, JP5 - NA, JP7 - NA.

DEMO Setup Instructions:
Set the DIP switches for Transmit Receive Mode SELF-TEST (Mode- 2).
In Mode -2 the program transmits SYNC words and incrementing data. The receiver fetches this data
and displays it on the console. Because the TEST bit is set in the Control Register 1 the line receiver and
both line drivers are disabled. The transmitted and received data will be looped back digitally. No signals
will be visible on the transmitter outputs.
Configure the Bit Rate DIP switches for 64 WPS ensuring that OPT2 is closed.
Open OPT1 DIP switch to configure the receiver for BPRZ mode.
After a power on reset, the program revision is displayed on the LEDs for two seconds in binary format,
where LED1 is the LSB. After two seconds, they LEDs turn off, then LED7 flashes every second as the
main MCU “live” operating indicator.
A message is also sent to the Console Port. Some of the displayed information reflects the options
selected by the Dip switches.
After resetting the board the program sends information to the console to summarize the configuration,
Receiver Mode, Word Rate and Slew Rate.

Press S1 to start
The HI-3717 has been successfully initialized and the program is waiting for the S1 push button to be
pressed before continuing on.
After pressing S1 the transmitter begins transmitting SYNC words and incrementing data words. The
receiver FIFO is checked for data at the same time, and captured data is displayed on the console.
The first data word in the sub-frame is the SNYC word (marked with an asterisk) followed by the
remaining number or words according to the Bit Rate selected by the DIP switches. Below there are 64
words total. The exact format of the console display may vary depending on the HyperTerminal setup or
PC window size.
