Production of the Manual IP switch has been discontinued, but you can build your own, based on the available source code.

Manual IP switch MK2

Intuitive remote control switching contains of two devices - IP control and IP relay driver - communicate via ethernet.
Suitably for realtime remote devices control, such as receiving antennas, power on/off for any some devices.

Manual IP switch consists of two parts:

• IP control
• IP relay driver rev0.4 (rev0.2)

Main functions:

• Low latency 1ms + your internet latency.
• up to 24 outputs:
  • 8 buttons
  • up to 16 encoder switch (one from)
• Relay configure remotely via telnet with access KEY
• Automatic nework pair by NET-ID, up to 256 devices
• Multi control - enable simultaneous operation up to 16 control to one IP relay - best for share between more users.
• Free configurable group buttons
  • groups gonfigured on IP relay CLI (command line interface)
  • in one group may be activate only one output
  • groups are free configurable
  • the group can be any size 2-8 buttons
  • there may be any buttons in the group, for example 1 and 8
  • the number of groups is not limited
• Blocking switching during PTT is ON
• Transfer PTT input from pin 18 D-SUB connector as one button (remote PTT)
• Ethernet plug detect with auto reinitialization
• Settings in serial CLI and source code.
• Very low TCP bandwidth, only eight bytes per every changes.
• Network latency (delay) is indicated by buttons light. Buttons light until after receive confirm packet from IP relay driver.
• Open Arduino platform allows you to customize firmware.
• 5V power from microUSB, or 8-15V from DB25 connector.
