Specifications

Quik start guide(Edit)

  1. Server box opens up over the upper part, lifting in the rear, and sliding backwards. Screwing not needed.
  2. Before connect power remove JP9 jumper (Introduction) from gpio board - switching the 5V power supply for RPI
  3. 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
  4. If power stable connected, connect Ethernet cable with DHCP on router enable to RPI and short JP9 jumper - now running and boot RPI server
  5. Web interface IP addres will tell your dhcp server or any network scan, for example Fing
  6. Default login: yourcall, password: 1234
  7. Front panel power switch paralel connected to first relay on gpio board - rotators may be power ON localy or remotely via web interface
  8. Front panel LED signals power in UPS input
  9. Rotator modules work independently to RPI server - how configure Single rotator interface
  10. Power for each rotator connect independently to rear panel terminal blocks.
  11. Web features configure via RemoteQTH-server
  12. Before Power OFF need shutdown server from web interface.

Have Fun!

Connectors(Edit)

  • 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(Edit)

  • 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(Edit)

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

RemoteQTH server presets(Edit)

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