RT CONNECT status screens

Below sets out the format of the status screens for the RT CONNECT. 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 operator�s 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 unit�s 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
Modem	This is the total data to the modem port on the rear of the unit, this runs at a fixed 115k
USB	USB port has no baud rate is not shown
Server RTCM	This is the number of valid RTCM bytes transferred over the LTE/4G connection
Serial RTCM	This is the number of valid RTCM bytes transmitted over the serial port
Modem RTCM	This is the number of valid RTCM bytes transferred over the modem port

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
interference, possibly from the vehicle ignition, consider rerouting/shortening cables.
