G15 - Modbus TCP to 2x RS232 + 2x RS485 (RTU/ASCII) Gateway
G15 - Modbus TCP to 2x RS232 + 2x RS485 (RTU/ASCII) Gateway
- Hybrid Modbus Gateway with 2 RS232 and 2 RS485 ports for mixed-signal environments.
Product Description
The Redisage G15 is a versatile Modbus Gateway designed for complex installations containing different types of serial devices. It combines 2 ports of RS232 and 2 ports of RS485 in a single unit, enabling seamless translation of Modbus TCP traffic to both legacy local devices and distributed field networks.
Like the rest of the G-series, the G15 is built on the robust STM32F4 platform. Key features:
• Hybrid Ports: 2x RS232 + 2x RS485
• Configuration: Web browser (built-in web server), Telnet or serial console
• Smart Translation: Modbus TCP <-> RTU/ASCII
• Flexibility: Gateway & Router modes on each port
• Termination: Built-in 120Ω resistors for RS485

About G15
G15 – The Hybrid Modbus Hub
The G15 Modbus Gateway is the ideal choice for facilities that operate a mix of older local machinery and distributed sensor networks. It offers 2 RS232 ports and 2 RS485 ports in one DIN-rail mounted chassis. This hybrid configuration allows a single device to act as a Modbus TCP gateway for local RS232 devices (like operator panels or laboratory scales) and remote RS485 chains (like HVAC sensors or power meters).
The G15 performs transparent protocol conversion, handling the nuances of Modbus RTU/ASCII timing and framing automatically. It supports advanced features such as Modbus ID Routing, which allows multiple serial ports to be addressed via a single TCP connection based on the Slave ID. The robust STM32F4 core handles high packet throughput without bottlenecks.
Technical Specifications:- Interfaces: 2x RS232 + 2x RS485 (Screw terminals).
- Conversion: Modbus TCP to RTU/ASCII.
- Power: 12-30 VDC (<1W consumption).
- Diagnostics: LEDs for Power, Error, Ethernet, and COM activity.
- Operating Temp: -40°C to +75°C.
Consolidate your Modbus infrastructure with the versatile G15. Configuration details can be found on our support portal.
