GW1101-1DI(3IN1)-DB-P(12-48VDC) is Modbus Ethernet gateway designed for integrating Modbus RTU/ASCII and Modbus TCP networks; they can achieve the conversion between Modbus RTU/ASCII and Modbus TCP protocols. This product supports 1 3IN1 DB9 serial port to 1 100M Ethernet copper port. It adopts wall mounting to meet the requirements of different application scenes.
Modbus gateway supports multiple network protocols, such as Modbus, TCP, IP, UDP, TELNET, ARP, ICMP, HTTP, HTTPS, SNMP, SSH,SMTP, SNTP,DNS and DHCP protocols. It possesses complete management function, and supports access control, rapid configuration, online upgrading, etc. RTU Master, RTU Slave, ASCII Master, ASCII Slave and other operating modes are supported; it supports up to 256 Modbus TCP client (master) accesses and connects up to 128 Modbus TCP server (slave) devices. TELNET, WEB, SSHD and other access modes are also supported. It can provide users with good experience with friendly design of network management system interface, simple and convenient operation.


  • Support 110bps-115200bps line speed and non-blocking communication
