    1. Connect the mini USB lead to your PC and then to the console connector J15 on the HI-8400 board; your PC should automatically install the driver. If not the driver FT231 can be installed from the Holt Flash drive. If you have problems installing the driver, please refer to the FTDI website below: 2.
  • Page 7 3. SPI data from the HI-8400 is read through the ‘Control Console’. This requires use of a terminal emulator for communication, such as HyperTerminal or Tera Term. Tera Term is used with Windows versions of Vista or later and is supplied on the Holt Flash drive. To install Tera Term: ●...
  • Page 8 To create this set up on the board just connect the 28V1 to 28V and GND1 to 0V, this produces an Open (high) in the GND/Open sensor 1, the other sensors will default to ‘0’. 8. To continually monitor the four outputs then use the key ‘z’, this will show a screen similar to below: Holt Integrated Circuits...
  • Page 9 The screen above is monitoring U3 sensors, ‘0000’ means all sensors are reading low. 2. Now increase the voltage source up to 9V, then increase the voltage slowly, to 10.5V, LED1 and LED S1 on the board should be lit, the screen should now read 1000, as shown below: Holt Integrated Circuits...
