All RaceAmerica LED Displays have a built-in safety net in the event the received data string gets truncated or garbles the last character (carriage return hex0D). The display will throw away bad data if it does not see the proper character string within a given amount of time to prevent locking up. Of course it is a double edge sword when sending data to the display typing manually. Too slow of data transfer and the display assumes a bad transmission and throws the partial string away before you can complete the typing.
With this data safety net, it is good practice to send the data to the display more than once with a small delay in between. This way if a wireless transmission is interfered with by RF noise, the next transmission will make it through and the display will process it and display the data.
