Module interface definition:

Module 4P terminal side:
VCC >+5V / +3.3V (module specification)
TXD >Send the TTL (UART) of this module, and the RXD receiving foot of the single -chip microcomputer
RXD >The TTL (UART) receiving of this module, the TXD sending foot of the single -chip microcomputer
GND >This module ground line (here must be connected to the ground machine system)

Module 5P terminal side:
R+/A >The A foot of this module needs to be connected to the T+/Y foot of other 422 modules
R-/B >In this module's B foot, you need to connect the T-/Z pin of other 422 modules
T-/Z >The Z foot of this module needs to be connected to the R-/B foot of other 422 modules
T+/Y >The Y foot of this module needs to connect the R+/A foot of other 422 modules
GND >In this module's ground line, some conditions can lead to the return path of the co -mode signal of the ground line as a signal. Of course, this line can not be used without conditions.
