Module introduction
MTCP01 network serial port transparent transmission module (NRP-MTCP01), through the network to TTL level serial port, can realize the two-way transparent transmission of network data and serial data, with TCP CLIENT, TCP SERVER, UDP SERVER, UDP CLIENT 4 working modes, serial port baud The highest rate can support up to 921600bps, which can be easily configured through the host computer software, which is convenient and fast.
Features
● Realize two-way transparent transmission of serial data and network data
● Support 10/100M, full-duplex/half-duplex adaptive Ethernet interface, compatible with 802.3 protocol
● Support MDI/MDIX line automatic conversion
● Support 4 working modes: TCP CLEINT/ SERVER and UDP CLEINT/ SERVER
● The serial port baud rate supports 300bps ~ 921600bps
● Support up to two independent serial ports at the same time, independent transparent transmission
● Serial port TTL level, compatible with 3.3V and 5V
● The serial port supports 5, 6, 7 or 8 data bits and 1 or 2 stop bits
● The serial port supports odd, even, no parity, blank 0, mark 1 parity mode
● The serial port supports full-duplex and half-duplex serial communication, and supports automatic switching of RS485 transceiver
● Support DHCP to automatically obtain IP address function
● Support DNS domain name system
● Support 0~2000ms serial port timeout setting ● Network parameters, serial port parameters can be configured through the host computer
● Support KEEPALIVE mechanism
