RS232 to RS485 / RS422 Serial Converter Header 9-pin Com Port Adapter with 4 Position Terminal Block Anti-surge

Product Features:
Zero delay, automatic transceiver conversion
With zero delay transceiver conversion function, no delay in data transmission, to ensure fast and smooth operation of industrial control systems.

l/0 circuit, automatic control of the direction of data flow
Automatic control of the direction of data flow, no need for handshaking signals. Ensure that the program written in RS232 half-duplex mode can be run in RS485 mode without changes.

High-speed transmission
The chip is equipped with an automatic transceiver switching function, which ensures faster signal transmission without delay.

Communication connection details:
1. Master-slave half-duplex communication, point-to-point.
2.Master-slave half-duplex communication, point-to-multipoint.
3.Extended 232 communication distance.
