od-t Sichuan Odot Automation System Co., Ltd 1. Product Overview 1.1 Product Functions Protocol converter is a converter developed by Sichuan Odot Automation System Co., LTD between RS232/485/422 and TCP/UDP.This protocol converter can easily connect serial port devices to Ethernet and realize network upgrade of serial port devices. Protocol converter supports the function of "data transmission", which can be set as a client or a server. This function can easily realize the data communication between PLC, server and other Ethernet devices and the underlying serial port devices. Modules that...

od-t Sichuan Odot Automation System Co., Ltd The paper clip can be used to click the reset button, and all the indicators blink once to indicate a successful reset. Gateway reset successfully, the technical parameters of the gateway are as follows: http:// www.odotautomation.com

od-t Sichuan Odot Automation System Co., Ltd 2.5 External terminal resistance According to the actual situation, a serial port side need external gateway 120 Q terminal resistance.RS485 bus in the case of no trunk to support a maximum of 32 nodes, node and node between the "Daisy chain" connection mode, in the communication cable at both ends need to add terminal resistance, the resistance http:// www.odotautomation.com

od-t Sichuan Odot Automation System Co., Ltd value is required to be approximately equal to the transmission cable characteristic impedance. In short distance transmission, no final resistance is required, that is, no final resistance is generally required below 300 meters. The final resistance is connected at the ends of the transmission cable. Gateway in field application, if the RS485 bus distance, big field interference will need to add 120 Q on both ends of the RS485 bus terminal resistance, in order to prevent the reflection of serial signal. Note: 120 Q resistance attached to the...

od-t Sichuan Odot Automation System Co., Ltd 3. Typical application S1E1 supports TCP server, TCP client, UDP pure transparent transmission mode. The transparent transmission mode supports transparent transmission with and without protocol. The S1E1 supports browser configuration and it directly forwarding data without storing. 3.1 Transparent transmission with protocol data Example: ODOT-S1E1 was used for testing. On-site RS485 device (MODBUS RTU communication protocol is adopted for communication, serial port parameters: ID=1,19200 BPS, N81). Modbus Slave test software was used to...

Od*t Sichuan Odot Automation System Co., Ltd set this parameter to be consistent with the device connected to the serial port. Parity checking: No check, odd check, even check can be selected, default no check, please set this parameter to the serial port. The connected devices are consistent. Stop bits: 1 bit, 2 bit stop is optional, default is 1 bit stop. Set this parameter to match the device to which the serial port is connected. Received character interval: The detection time of frame interval when receiving a message, 1.5t~200t optional, default 3.5T (T is the time of single character...

2.In the webpage setting interface, the configuration parameters of the protocol converter are set according to the serial port parameters of the serial port device. Serial Server DHCP Enabled Subnet mask parity bits Message frame interval Slave response time(ms) Protocol type server address Note: There are two modes available for transmission: RTU_MODE and ASCII_MODE. Select RTU_MODE here. Ethernet connection mode has TCP_SERVER, TCP_CLINET, UDP_CONNECT three ways to choose. Select the TCP_SERVER mode here. 3. After setting the parameters, click Submit configuration to download to the...
