ACS2 2021 controller (ACS2 2020 for reference), after pressing the "∞" smart key to enter the mapping mode, mapping is still unavailable

There are hardware problems and external causes. The troubleshooting steps are as follows:

1. When inserting the RTK module, there are two segments of voice, namely, "the device has been inserted" and "the positioning module has been connected". If there is no "positioning module is connected" voice. It is probably a hardware problem.

2. If you enter the mapping mode, the sixth indicator does not turn green or red, which is probably also a hardware problem.

3. It is easy to exit RTK in the process of use, which may be caused by poor 4G network, blocked RTK antenna, loose interface, etc., which need to be further tracked.

a) : If the antenna is lifted vertically and there is no obstruction, it can be eliminated

b) : Check the 4G network condition, plug in the SIM card, and if the network is good and the Internet is available, it can also be eliminated

c) : The possibility of interface looseness is high, you can try to replace the device to eliminate it
