Why is the number of serial channels limited?
At a serial data rate of 115200 there is a limitation in the number of channels that can be transmitted. This is limited further by higher VBOX log rates like 50 and 100Hz. At 20Hz (or less) it is possible to transmit all the VBOX standard channels plus 32 CAN channels. At 50Hz it is only possible to transmit the standard VBOX channels. At 100Hz it is only possible to transmit the channels Sats, Time, Velocity, brake trigger event time. On a VBOXIII the channels are automatically limited on the serial data stream according to the selected log rate. When using the VBOX serial outputs with a Racelogic Telemetry system, the telemetry link has a Radio data rate of 9600baud. As such a VBOX must have the serial set to 5Hz when used with the telemetry link.
