Disable UART1/UART2 communications

When configuring the 4G NTRIP Master, UART1/UART2 communications (out) need to be disabled.
In this quick tutorial we will cover this, for both the simpleRTK2B and simpleRTK3B modules.

simpleRTK2B Budget

Connect your receiver via the POWER+GPS port
Open u-center and connect it to your receiver
Go to View > Messages View > UBX-CFG-PRT
Set target UART1, click Poll and write down Protocol Out
Set Protocol out to none
Click Send
Set target UART2, click Poll and write down Protocol Out
Set Protocol out to none
Click Send
Go to UBX-CFG-CFG
Select Save current configuration
Click Send
You have now disabled all communications (out) on UART1 and UART2 and can proceed to program the 4G NTRIP Master
If you want to restore the original settings, repeat the same process and set UART1/UART2 Protocol Out as it originally was

simpleRTK3B Pro and simpleRTK3B Heading

Connect your receiver via the POWER+GPS port
Wait 10 seconds
Open a browser and type http://192.168.3.1/
Go to NMEA/SBF Out, write down or take a screenshot of the settings
Delete any COM2 settings
Save settings in the memory (bottom right popup)
You have now disabled all communications (out) on COM2 and can proceed to program the 4G NTRIP Master
If you want to restore the original settings, repeat the same process and set COM2 settings as it originally was
We suggest that you go to Corrections > Input > COM2 and set RTCMv3, click Ok and Save changes

simpleRTK3B Budget and simpleRTK3B Compass

Connect your receiver via the POWER+GPS port
Connect your receiver to Uprecise
Make sure your receiver has the latest firmware, You can type VERSION.
For simpleRTK3B Budget firmware version must be >=UM980_R4.10Build20739
For simpleRTK3B Compass, firmware version must be >=UM982_R4.10Build23575
To disable UART2, type: CONFIG RXTYPE COM2 NONE
To disable UART3, type: CONFIG RXTYPE COM3 NONE
Do not save the changes via SAVECONFIG, simply resetart your device once you are done to revert these last changes
