Wiring Definition
Terminal side of module 4P:
VCC: +5V/+3.3V (module specifications)
TXD: TTL (UART) of this module is sent, and RXD receiving pin of MCU is connected
RXD: TTL(UART) of this module is received, connected with the TXD sending pin of MCU
GND: Ground wire of this module (the ground wire must be connected to the ground of the SCM system)
Terminal side of module 5P:
R+/A: Pin A of this module should be connected to pin T+/Y of other 422 modules
R-/B: Pin B of this module should be connected to pin T-/Z of other 422 modules
T-/Z: Z pin of this module should be connected to R-/B pin of other 422 modules
T+/Y: Y pin of this module should be connected to R+/A pin of other 422 modules
GND: the grounding line of this module. If some conditions permit, the grounding line can be used as the back flow path of common mode signals. Of course, this line can not be used when conditions do not allow.
