III. Core Functional Features
Multi-channel Independent Serial Port Integration Design
The board integrates multiple independent serial communication channels. Each channel is electrically independent and does not interfere with each other. It can simultaneously connect different types of serial port peripherals, meeting the usage requirements of one industrial host to connect multiple on-site devices, significantly expanding the communication capacity of the entire machine.
Free Switching of Communication Modes
It supports three mainstream industrial serial port modes: RS-232, RS-422, and RS-485. Through the onboard dip switch, the communication mode can be quickly switched. For short-distance point-to-point communication, RS-232 is selected; for long-distance differential transmission, RS-422 full-duplex or RS-485 half-duplex is selected. It is compatible with different wiring distances and communication architectures in the field.
Full Channel Electrical Isolation Protection
Each communication channel is equipped with an optical isolation circuit, featuring high-level electrical isolation performance, which can effectively isolate industrial site pulse interference, static interference, and ground potential difference interference generated by frequency converters, large-power motors, contactor startups and stops, eliminating communication garbled, data interruption, and interface burnout problems, significantly improving the stability of communication under harsh conditions.
Wide Range of Communication Baud Rate Adaptation
It supports industrial full-frequency band commonly used baud rates, covering from low-speed debugging levels to high-speed transmission levels, and can match various imported and domestic industrial peripheral communication parameters. Data bits, check bits, and stop bits can be freely configured through the system software and are compatible with most custom serial port protocols and standard industrial protocols.
Bus-Free Complex Configuration
It uses the standard ISA industrial bus to connect with the host, and the hardware can be inserted into the slot for physical installation. The old industrial control system does not need to install complex drivers. The system automatically recognizes hardware resources upon power-on and only requires simple configuration of serial port addresses and communication parameters to be put into use. The installation and debugging process is simple and efficient.
Industrial-grade Durable Structural Design
The entire card uses thickened industrial PCB board materials and selects wide-temperature-level electronic components. The board layout is regular, and it has excellent resistance to vibration and dust. It is suitable for harsh environments such as machine vibration workshops, high-temperature production workshops, and humid chemical workshops, meeting the requirements for 24-hour uninterrupted continuous operation of equipment.
Integrated Status Indicator Lights The board card is equipped with corresponding channel communication status indicator lights, including power indicator, data transmission indicator, and data reception indicator. On-site personnel can directly judge whether the channel is powered on and whether the data is transmitted and received normally through the light status, quickly identify the communication fault location, and simplify the daily operation and maintenance troubleshooting work.
The built-in terminal resistor is compatible with networking
The board card reserves a terminal resistor activation switch. In the RS-485 bus-type networking scenario, the onboard 120Ω terminal resistor can be directly activated without the need for additional external resistor accessories, simplifying the on-site wiring construction and effectively eliminating the problem of signal reflection in long-distance transmission.
