Broken URM04 PCB

On my URM04 V2.0 there is no welded jumpers (no"A" nor "B"). Have I to bridge it anyway when it is in a network?

Hi
For URM04 Ultrasonic Sensor (RS485) SKU:SEN0002
Could you please share us a picture of the broken PCB? If the pad and circuit is still fine, you can try welding the RJ485 jack by yourself and it should work.
