1. Product Overview
1.1 Product Functions
ODOT-S4E2, developed by Sichuan ODOT Automation System Co., Ltd., is a Modbus RTU to
Modbus TCP/IP protocol converter based on market demand and years of experience.
By applying ODOT-S4E2, all the Modbus RTU/ASCII slave devices with RS485/RS422/RS232 port
could connect to Modbus TCP/IP network and communicate with TCP clients. It could realize high speed
data transmission by connecting the low speed serial device to the high-speed Ethernet. This protocol
converter provides two working modes of transparent transmission and mapping mode, which could
achieve the maximum system compatibility.
