tGW-700 Series

The tGW-700 is a Modbus TCP to RTU/ASCII gateway that enables a Modbus/TCP host to communicate with serial Modbus RTU/ASCII devices through an Ethernet network, and eliminates the cable length limitation of legacy serial communication devices. The module can be used to create a pair-connection application (as well as serial-bridge or serial-tunnel application), and can then route data over TCP/IP between two serial Modbus RTU/ASCII devices, which is useful when connecting mainframe computers, servers or other serial devices that use Modbus RTU/ASCII protocols and do not themselves have Ethernet capability.

  • Supports Modbus TCP/UDP master and slave
  • Supports Modbus RTU/ASCII master and slave
  • Max. TCP connections (masters) per serial port: 32 (tGW-71x), 16 (tGW-72x) or 10 (tGW-73x)
  • Read-cache ensures faster Modbus TCP/UDP response
  • Supports UDP responder for device discovery (UDP Search)
  • Static IP or DHCP network configuration
  • Easy firmware update via the Ethernet (BOOTP, TFTP)
  • Tiny Web server for configuration (HTTP)
  • Contains a 32-bit MCU that efficiently handles network traffic
  • 10/100 Base-TX Ethernet, RJ-45 x 1 (Auto-negotiating, auto MDI/MDIX, LED Indicators)
  • Includes redundant power inputs: PoE (IEEE 802.3af, Class 1) and DC jack
  • Allows automatic RS-485 direction control
  • 3000 VDC¬†Isolation and +/-4 kV ESD protection for i versions
  • Male DB-9 or terminal block connector for easy wiring
  • Tiny form-factor and low power consumption
  • RoHS compliant & no Halogen
  • Cost-effective Modbus gateway
