Serial device server ZLAN5443A

ModbusEthernet4 ports

ZLAN5443A is new generation of 4 ports serial device server developed by Shanghai ZLAN. Compared with ZLAN5400A, ZLAN5443A is more cost-effective as it use the third generation hardware technology, and ZLAN5443A support Modbus TCP to Modbus RTU Gateway function. Modbus Gateway support multi Modbus clients connecting and read data at the same time, as “multi-host” function. ZLAN5443A support 4 RS232 serial ports, 4 RS422/485 ports, realize 4 ports simultaneous full-duplex working by connecting to ZLAN5443A via a cable. It’s the ideal choice of multi-serial ports networking. ZLAN5443A support extending to 8/12/16 ports through cascade Ethernet port, up to 32 serial ports. Feature Hardware characteristics 1) All four serial ports support RS232, RS485 and RS422 serial ports. 2) The four serial ports can work independently in full duplex without interference, and can be configured with different baud rates. 3) Support network switch function of 2 network ports, can be used as switch at the same time. 4) Abundant indicator light, each serial port has a separate TCP connection indicator light and data activity indicator light. 5) Shanghai ZLAN patented products, leading technology. Patent No. ZL 2014 2 0108890.3. Software features 1) Support TCP server, TCP client, UDP mode, UDP multicast. Supports 10 TCP connections as a TCP server. 2) Baud rate support 1200 ~ 460800bps, data bit support 5 ~ 9 bit, check bit can be no check, odd check, even check, mark, space five ways, support CTS/RTS hardware flow control and XON/XOFF soft-flow control. 3) Support device connection to send MAC address function, convenient cloud management device.
