5V RS422 Mutual To TTL Bidirectional Signal Module Full Duplex 422 To MCU UART Serial Board Overvoltage Overcurrent Protection

5V RS422 Mutual to TTL Bidirectional Signal Module Full Duplex 422 to Microcontroller UART Serial Board overvoltage overcurrent protection

Features:

1. The two-terminal terminal design can be used for better wiring.

2. This module is suitable for the mutual conversion of 5V TTL and RS422 signals.

3. With overvoltage and overcurrent protection, real-time protection of RS422 level signal.

4. Except for the pins, this module uses SMD components to ensure better signal transmiion.

Module 4P terminal side:

VCC: +5V

TXD: The TTL (UART) transmiion of this module is connected to the RXD receiving pin of the microcontroller

RXD: TTL (UART) receiving of this module, connected to the TXD sending pin of the microcontroller

GND: The ground wire of this module (this ground wire must be connected to the ground of the microcontroller system)

Module 5P terminal side:

R+/A: A pin of this module, need to be connected to T+Y pin of other 422 modules

R-/B: The B pin of this module needs to be connected to the T-/Z pins of other 422 modules

T-/Z: The Z pin of this module needs to be connected to the R-/B pin of other 422 modules

T+/Y: The Y pin of this module needs to be connected to the R+/A pin of other 422 modules

GND: The ground wire of this module. If some conditions allow, the ground wire can be drawn out as the return path of the common mode signal of the signal. Of course, this wire can not be used when the conditions do not allow it.
