Why is the number of serial channels limited?

Table of contents
No headers
 

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 100 Hz.

 

At 20 Hz (or less) it is possible to transmit all the VBOX standard channels plus 32 CAN channels.

At 50 Hz it is only possible to transmit the standard VBOX channels.

At 100 Hz it is only possible to transmit the channels Sats, Time, Velocity, brake trigger event time.

On a VBOX3i 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 9600 baud. As such a VBOX must have the serial set to 5 Hz when used with the telemetry link.
