Quik start guide

  1. Before connect power remove JP9 jumper from gpio board - switching the 5V power supply for RPI
  2. Power may be from two sources. If you use only one source, connect power to UPS input - this is monitoring internal A/D converter and LED on front panel).
    1. 24V DC from power supply
    2. 24V UPS from backup battery circuit
  3. If power stable connected connect Ethernet cable with DHCP on router enable to RPI and short JP9 jumper - now running and boot RPI server
  4. Web interface IP addres will tell your dhcp server or any nettworg finger, for example Fing

Connectors

  • J1 +24V DC Power
  • J6 J15 - four rotator interface AC od DC Power
  • J5 - RJ9 connector for other I2C temp sensors
  • P16 - where the relay switch voltage on outs, here is voltage IN
  • P1-P12 - GPIO Relay outputs
  • J7-J10 - connect four rotator interface

Jumpers

  • J2 - Power switch and LED
  • J11 - two free A/D inputs
  • I2C - set address A/D converter
  • JP1-JP8 - preset power each rotator interface separately
  • J4 - I2C bus
  • J3 - switched +5V for USB hub
  • Green 1-4 - measuring points input four A/D converters

Trimmer

  • R27-R30 - voltage divider for A/D converter

RemoteQTH server presets

typycaly set A/D converter - It depends on the settings of the input voltage divider (Trimmer R27-R30)
