## Summary description

The PLANET 1-Port RS232/422/485 Modbus gateway/controller features a compact design with external power requirements of 5V DC and a typical power consumption of 5.5W. It is suitable for various industrial applications, ensuring reliable communication over Modbus protocols. Its dimensions are 97mm x 70mm x 26mm, making it easy to integrate into existing systems.

## Long description

PLANET MG-115A is a compact 1-port RS232/422/485 Modbus gateway/controller that converts between Modbus TCP, Modbus RTU and Modbus ASCII. Designed for industrial networks, the device supports integration of serial equipment into Ethernet-based Modbus TCP systems and can be used to migrate SNMP-managed devices to Modbus TCP for longer-distance Ethernet interconnection. The gateway requires an external 5V DC supply, consumes typically 5.5W, and measures 97 mm x 70 mm x 26 mm.
Advantages
The MG-115A provides protocol conversion across Modbus TCP, RTU and ASCII, enabling communication between different Modbus devices and systems. Its single serial port supports RS232, RS422 and RS485 interfaces for flexible connection to a wide range of industrial equipment. The compact enclosure and low power draw simplify installation into existing control cabinets and automation racks.
Suitable for
 Connecting serial Modbus RTU/ASCII devices to Modbus TCP networks
 SCADA and HMI integration with serial field devices
 Migrating SNMP-managed devices to Modbus TCP for Ethernet interconnection
 Small- to medium-scale industrial automation installations
Key specifications
 Model: PLANET MG-115A (MPN: MG-115A)
 Serial interfaces: 1-port configurable RS232 / RS422 / RS485
 Supported protocols: Modbus TCP, Modbus RTU, Modbus ASCII
 Power input: 5 V DC (external)
 Typical power consumption: 5.5 W
 Dimensions: 97 mm x 70 mm x 26 mm
 Colour: Black
How to use
Install the MG-115A in a suitable enclosure or DIN-rail location and connect the serial device to the gateway using the appropriate RS232, RS422 or RS485 wiring. Provide external 5V DC power and connect the Ethernet port to the Modbus TCP network. Configure the gateway via its management interface to select the desired serial mode and protocol mapping between Modbus TCP and Modbus RTU/ASCII. Verify communication with connected SCADA or HMI systems and adjust serial parameters (baud rate, parity, data bits, stop bits) as required.
Usage recommendations
Use shielded cabling for serial and Ethernet connections in electrically noisy industrial environments, and confirm grounding practices to reduce communication errors. For reliable operation, match serial interface settings on both the gateway and connected devices and test the configuration in a controlled environment before full deployment.
