GR and Mini radios will also report the Transmit Current of the radio FGR2 radios will not Flow Control True flow control cannot be accomplished with any MoTeC product in their current states of software development A work around hack for flow control can be created by utilizing the CTS clear to send line as a transmission control line in the telemetry setup in the dash The CTS line of the radio should be connected up to a digital input Then this digital input channel will be used as the transmission control line under the advanced telemetry settings It will help to minimize the buffer overflow but not entirely prevent it The CTS line is updated at the radio side after every Byte of data But on the MoTeC side the transmission control line only updates at 50 Hz Therefore a time delay exists in the radio saying stop sending and the MoTeC actually stopping its transmission which will result in a few bad packets This archaic flow control is still useful at rates higher than 38400 or in noisy environments Buffer Each radio has an internal buffer which is 2000 Bytes long When the throughput of data between the radios becomes slower than the data streaming into the radio this buffer will fill up When the throughput of data between the radios is faster than the incoming data it will empty When the buffer gets full new incoming data is written over the existing data in the buffer starting from the beginning of the buffer So a
