2. Recommendations for remote displays (sign boards) or data loggers.

• Look at the Approaching Target byte. If it is 4 or above, display it.

• If messages are not arriving, blank screen after a few seconds. The radar is probably off, or not

connected.

• Displaying the difference between the sign receiving a speed of zero and not receiving a message

at all is recommended. This makes troubleshooting easier. We display a dot if communications

are working properly.
