Product Introduction

PCM Cable Co., Ltd. is one of the leading rs232 to rs422 485 adapter with cable manufacturers and suppliers in China. Welcome to wholesale high quality customized products at discount price from our factory. Contact us for quotation and free sample.

In order to facilitate remote data communication between computers, external devices or intelligent instruments equipped with different standard serial interfaces, the mutual conversion of standard serial interfaces must be carried out.

This RS232 to RS422/485 Converter can convert single-ended RS-232 signals into balanced differential RS-485 signals. The RS232 female port is connected to the RS485 end male connector, and the 485 end is equipped with a terminal block. It has a built-in fast transient voltage suppression protector to protect RS -485 interface

Application

The RS232 to RS485 converter can be applied to form a point-to-point, point-to-multipoint remote multi-machine communication network between the main control machines, between the main control machine and the microcontroller or peripherals, and realize multi-machine response communication.

It is widely used in the industrial automation control systems, all-in-one card, access control system, consumer system, attendance system, parking lot system, self-service banking system, bus toll collection system, highway toll station system, Programmable Logic Controllers (PLCs), Process Control Systems, Data Acquisition Systems and so on.

Features of RS485 communication

1. Use differential signals.

2. The RS485 communication rate is fast, and the maximum transmission rate can reach more than 10Mb/s.

3. The combination of balanced driver and differential receiver is used inside RS485, which greatly increases the anti-interference ability.

4. The longest transmission distance can reach about 1200 meters.

5. Networked multi-machine communication can be carried out on the bus.

6. The RS485 interface is very simple. The common hardware interface is MAX485
