Key Description:
Module Description:
1. RS422 interface, bidirectional communication. ABYZ ultra-long transmission range of 1000 meters.
2. The module has 15KV ESD protection.
3. An 10-ohm current-limiting overcurrent protection resistor is added on the board.
4. The module has a TVS diode. It can resist lightning strikes and peak voltages.
5. The module has a 120-ohm terminal resistor, which can effectively reduce echo interference in long-distance communication.
6. There are power indicator lights and data transmission/reception indicator lights. The data status is clearly visible.
7. On the TTL side, it uses 5V DC power supply. RXD and TXD are compatible with 5V logic signals.
8. The module uses the original imported MAX490 chip, which has a stability and communication speed far exceeding domestic products, reaching up to 2.5MBPS.
9. Module size: 5.0cm * 2.7cm
