PC-E Gateway Protocol Converter
Serial Modbus to Ethernet Gateway

Serial Modbus RTU Protocol to Modbus TCP/IP Ethernet Converter for PLC, HMI, SCADA, etc.

The model PC-E Protocol Converter (Serial Modbus / Ethernet) is an interface to bridge Serial Modbus devices, such as Future Design Controls FDC-IO Series (Digital / Analog IO to Modbus RS232/485) to computer hosts running Modbus/TCP on Ethernet networks (10/100 Base-TX Ethernet network). The PC-E may be connected to multiple Serial Modbus devices and multiple PC-E converters may be connected to Ethernet networks.


  • Convert Serial to Ethernet for Legacy
  • Data Acquisition
  • Remote IO


  • Easy to Install and Use
  • Bridge Serial Modbus to Ethernet TCP/IP
  • Connect to Multiple Serial Devices
  • Allow up to 4 Masters to access device

Fully compliant with Modbus/TCP, the PC-E offers a convenient solution to connect existing devices or controllers running Modbus Serial protocol (Modbus/RTU) to an Ethernet network.

The Ethernet/Serial Converter can be configured to operate in a number of different modes depending on the application. It can be configured as a transparent data link or it can perform the gateway function of converting Modbus TCP messages to Modbus RTU messages.

Serial Modbus RS232 to 485 Converters

Model SN10A is a DIN Rail mountable, industrial grade RS232 to 485 converter. Powered by 90-264VAC the SN10A can drive up to 32 standard devices (12 Kohm input) or up to 247 devices high impedance (96 Kohm input) devices, such as Future Design Control's interface products.

The SN10A DIP switch configurable Baud rate, Parity, Data & Stop bits so there is no software required to be installed on a PC. Just configure the SN10A using the DIP switches, connect to a PC (Serial port), connect the serial devices and you are ready to go.


  • Convert PC Serial RS232 to RS485
  • Data Acquisition
  • Remote IO


  • Easy to Install and Use
  • Convert USB to Serial RS232 to RS485
  • Indicator Lights minimize Troubleshooting

An optional USB to Serial converter is available allowing the SN10A to be used on PC's without a serial port. These are plug & play devices requiring driver install on your PC, plug in one end to PC's USB and the serial end to the SN10A.
