RTLIVEV2-MotorsportAndIndustrial / StatusLCD

Status LCD

The current status of the connection to the server, internal data storage, and port data is displayed on the 2 line x 16 character display on the front of the unit.

In normal operation the unit cycles over the screens continuously.

Unit status

Unit name Unit serial number
Firmware and hardware version Current CPU load

Note that the CPU load should be under 75% in normal operation. If above 75% then consider the configuration.

LTE status

LTE status, or if available the operatorís name Signal strength
Data rate from server to unit Data rate from unit to server

The signal strength is derived from the total turnaround time for communications with the server. That is the time to send a message to the server and get a response. Under optimal conditions, the total turnaround time is approximately 0.2 seconds.

The maximum data rate with the server is about 1Mbit.

Satellite status screens

(only displayed for products with the optional RTK GPS option)

Satellite constellation name Freq 1: satellite count Freq 2: satellite count

The constellation names are GPS, GAL(ileo), GLO(nass), BEI(dou)

GPS status

GPS update rate Current positional accuracy
Number of satellites in use RTCM correction status

Note that GPS is displayed for simplicity, however this is for all satellite constellations, including GPS, Glonass, Galileo and Beidou

Logging status

When not logging this displays the amount of data currently buffered in the unitís internal memory

When logging this displays the name of the file that is being uploaded, and the time the unit has been logging for.

Port status

Port name Configured baud rate, if E is displayed then errors are detected
Data rate received by the unit Data rate transmitted from the unit
Port name Description
Serial This is the on the front of the unit, and can be configured to 430k or 115k
USB USB port has no baud rate is not shown
CAN CAN port
GPS This shows the total data communication with the internal GPS receiver, useful for diagnosing issues
Server RTCM This is the number of valid RTCM bytes transferred over the LTE/4G connection
GPS RTCM This is the number of valid RTCM bytes transferred to the internal GPS receiver

Note that this is only display if there is either some data being received or transmitted on the relevant ports.

If the E is displayed after the baud rate, then there are errors detected. Typically this is due to one of the following:

  • incorrect baud rate
  • an intermittent wiring or connector fault
  • incorrect CAN termination
  • interference, possibly from the vehicle ignition, consider rerouting/shortening cables.
