III. Core Functional Characteristics
Multi-channel Independent Serial Port Expansion
The card integrates multiple independent serial communication channels, with each channel's electrical components being completely independent and not interfering with each other. It can simultaneously connect multiple different types of on-site peripherals, effectively solving the problem of insufficient native serial ports in old industrial hosts, and significantly enhancing the overall external communication expansion capability.
Three Modes of Communication Switching
A single channel supports RS-232, RS-422, and RS-485 three industrial mainstream serial port modes. Through the onboard physical dip switch, the mode can be quickly switched without changing the wiring and program. For short-distance communication, RS232 is selected, for long-distance bidirectional communication, RS422 full-duplex is used, for bus networking with multiple devices for data collection, RS485 half-duplex is selected. It meets the requirements of all scenarios for wiring.
Full Channel Optical Isolation Protection
Each communication channel is equipped with an independent optical isolation circuit, with high-level withstand voltage isolation capabilities, which can effectively isolate industrial site motor start-stop, frequency converter operation, large-power contactor-generated electromagnetic interference, static electricity shock, and ground potential difference interference. From the hardware level, it avoids communication garbled, data connection loss, and interface burnout faults, significantly improving the stability of operation in harsh conditions.
Full Frequency Band Communication Rate Compatibility
It supports all common industrial communication baud rates in the field, covering the range from low-speed debugging to high-speed transmission. The data bits, check bits, and stop bits can be freely configured within the system, perfectly compatible with standard industrial serial port protocols and various devices' custom private communication protocols, suitable for connecting and using various industrial control peripherals at home and abroad.
ISA Bus Driver-Free Compatibility
It adopts a standard 16-bit ISA industrial bus interface, relying on the host slot to directly draw power, without the need for additional external power supply. After installation, it can be automatically recognized in old industrial systems such as DOS, WIN95, WIN98, and WIN2000, without complex driver installation. Only simple configuration of serial port resources is required to put it into use. Deployment is convenient and efficient.
Built-in Terminal Resistor for Convenient Networking
The card comes with a 120Ω communication terminal resistor and an independent dip switch control switch. In RS485 bus networking wiring scenarios, it can be directly enabled by turning on, without the need for additional external resistor accessories. It quickly eliminates signal reflection problems caused by long-distance transmission, ensuring the integrity of long-distance communication signals.
Intuitive Status Light Diagnosis The board card is equipped with power indicator light, data transmission indicator light and data reception indicator light, which clearly show the operating status of each channel. On-site maintenance personnel can quickly determine the power-on status and data transmission status of the channel, and quickly locate the communication fault point, thereby reducing the maintenance time.
Lead-free environmental-friendly industrial process
All components, solder, and plates of the entire card are made of lead-free environmentally friendly materials, without harmful substances, meeting the requirements for environmental compliance of modern industrial equipment and the compliance requirements for exported equipment. At the same time, it continues to use industrial-grade wide-temperature component selection, with resistance to high and low temperatures, vibration resistance, and dust resistance, and supports uninterrupted continuous operation 24/7.
VII. Hardware Overall Specifications
The entire card adopts an industrial standard ISA full-length board card structure. The shape size and installation holes are exactly the same as the original 4810E. It is compatible with all ISA slot industrial control equipment. The communication output end adopts a sturdy industrial terminal design, with strong shock resistance. It is unlikely to cause line loosening and detachment under long-term equipment vibration. The overall operating power consumption is low, and the temperature rise during long-term operation is low, without causing a burden on the internal heat dissipation of the host. The working temperature of the entire machine covers the normal industrial site usage range, and the storage temperature meets the requirements for equipment storage and long-distance transportation environments. The environmental adaptability is excellent.

XII. Fault Diagnosis and Daily Maintenance
During daily use, keep the industrial control chassis ventilated and unobstructed, regularly clean the dust accumulated on the surface of the board card and the internal part of the ISA slot, wipe and clean the gold fingers of the board card, avoid oxidation causing poor contact; When there is no data interaction in communication, first check if the selection of the communication mode of the dip switch is correct. Confirm that the communication parameters of both devices are unified. Check if the positive and negative poles of the communication lines are connected correctly without any reverse or misalignment.
When there are packet loss or unstable transmission of communication data, investigate the strong electromagnetic interference sources on site. Move the communication lines away from the power cables. In long-line networking scenarios, promptly activate the terminal resistors.
When the channel indicator lights show no movement, check if the board is properly installed. Investigate the faults of the ISA slot and the conflict of the serial port resource addresses within the system.
When a single channel is abnormal while the other channels are working normally, you can directly switch to the backup channel for use, without affecting the normal operation of the remaining communication functions of the entire card.
