It has been a few weeks since my last update about the IC-706 remote rig project so here is a new one.
In my previous post I described how I solved the power connections for the radio and the front panel when they are physically separated from each other. In this post I will explain the software part of the power on / off procedure.
Yesterday I have implemented emulation of keep-alive messages on server side. This means that the keep-alive messages sent by the front panel roughly every 100 ms are no longer sent over the network; instead, they are generated in the servers main loop with 150 ms interval.
In my first post about the IC-706 remote kit I wrote that we don’t really need to care about what data protocol is used between the radio and the front panel; all we need is to route the data between a serial port and a network socket. However, it turns out that taking a closer look at the protocol is not only a good idea but also necessary for efficient remote control.
