User Manual for Embedded Dual Network Port TRDP Module

   The NETMODUD-P1.02 module is an Ethernet&TRDP module to TTL serial interface and Ethernet UDP interface series protocol conversion module produced by Guangzhou Zhongzhi Cheng Information Technology Co., Ltd. Ethernet defaults to full duplex 100Mbps. The default baud rate for TTL serial ports is 115200bps, and customized services are required for other baud rate requirements. Ethernet port 1 is used as the TRDP interface to connect with the train network, while Ethernet port 2 uses UDP communication to connect with user devices. By default, communication port 6666 is used for packet transmission and reception. This module also provides router functionality based on the TRDP network. Users can use this module to directly communicate with other devices via UDP communication on the TRDP network.
