maintenance”.
TC-430™ normally exchanges data with LED signs over a serial line at 9600 bps. Usually during
firmware/configuration/fonts update procedure such a speed is increased in order to shorten up the duration
of the whole task. The serial speed used during maintenance tasks can be set at “Setup
Displays setup
Displays maintenance
Maintenance baud rate”, as shown in Figure 77.

The default is 57600 bps, but slower speeds can be attempted if the signs update procedure repeatedly fails.
