About C22
C22 – Flexible Serial-to-Ethernet Integration
The C22 Serial Device Server is the ultimate tool for engineers who need to bridge the gap between serial-based industrial machinery and Ethernet-based IT infrastructure. Equipped with 2 configurable ports (RS232/RS485), this device allows you to network-enable PLCs, HMIs, barcode scanners, and CNC machines.
Using the included Virtual COM software (Download SW01), the C22 creates virtual ports on your Windows PC (e.g., COM3, COM4) that map directly to the remote serial devices over the LAN. This means existing software applications can communicate with remote equipment without any code modification.
The device offers versatile management options, including a built-in Web Server, Telnet, or a serial console, allowing for easy deployment in any environment.
Technical Specifications:- Serial Interface: 2x RS232 (Tx, Rx, GND) OR 2x RS485 (A, B).
- Operating Modes: Virtual COM, TCP Server, TCP Client, UDP.
- Configuration: Web Browser, Telnet, Serial Console.
- Performance: Baud rates up to 115200 bps.
Whether you need to monitor a remote solar inverter or control access gates, the C22 offers the connectivity you need. Full manual available in the support section.
3 Year Warranty
Your previous questions regarding this product
1. What is the main purpose of the C22 converter?
This converter is a comprehensive hardware and software solution that enables the creation of remote communication ports. It facilitates communication between devices with RS232/RS485 interfaces and an Ethernet network, allowing for remote access and management of industrial equipment.
2. What models are available in the C20-C25 series, and what is a difference between them?
The non-Wi-Fi version of the series includes six models: - C20: 2x RS232 - C21: 1x RS485 - C22: 2x RS232/RS485 - C23: 4x RS232 - C24: 4x RS485 - C25: 2x RS232 + 2x RS485 Models C20–C22 are based on the ESP32 microcontroller, while models C23–C25 use the STM32 platform. If you're interested in models with Wi-Fi support, we recommend exploring our C30-C32 series.
3. What configuration methods are available for this device?
Devices can be configured via: - Web browser: access the configuration panel using the device's IP address - Telnet console: connect via Telnet - Serial console: direct access through the serial port - Redisage Configurator application: create virtual COM ports on a PC
4. Is this converter suitable for industrial applications?
Yes. With a wide operating temperature range (-40°C to +75°C), DIN rail mounting, and ESD protection, the C22 device is designed for harsh industrial environments and meet relevant safety standards.
5. What power supply options are available for this device?
The device operates on a DC voltage range from 12 to 30 V, offering flexibility for different industrial installations.
6. Is it possible to restore factory settings on the device?
Yes, factory settings can be restored either via the web interface in the device section or using the service mode.
7. Where can I find technical documentation and user manual?
Full technical documentation, including user manuals and datasheets, is available on the manufacturer’s website.
8. Can multiple converters operate in the same network?
Yes, multiple devices can be used within the same Ethernet network. Each device has its own IP address, allowing independent communication with various serial ports across different locations.
9. Does the converter support the Modbus protocol?
Yes, these devices support data transmission using Modbus RTU, ASCII, and TCP protocols. This can be achieved through serial-to-virtual COM port conversion or TCP/IP access.
10. Can the device firmware be updated remotely?
Yes, the firmware can be updated remotely via the web interface, enabling quick deployment of updates and new features without physical access.
11. Is product customization available to meet specific requirements?
Absolutely! Please contact us via the form, email, or phone. Share your requirements and ideas with us—we’re here to support you throughout the entire device development and production process.
