User manual Version 1.1 ABLELink® Ethernet-Serial Server GW51C-MAXI 1. Introduction The Atop GW51C-MAXI Ethernet-Serial Server is a gateway between Ethernet (TCP/IP) and RS-232/RS-485 communications. The information transmitted by GW51C-MAXI is transparent to both host computers (Ethernet) and devices (RS-232/RS-485). Data coming from the Ethernet (TCP/IP) is sent to the designated RS-232/RS-485 port and data being received from RS-232/RS-485 port is sent to the Ethernet (TCP/IP) transparently.
