Product Descriptions

NB144S is a 4-way serial port server. It integrates the TCP/IP protocol stack inside, which can realize the two-way transparent transmission of data from the 4-way serial port to the Ethernet port. The device has the function of ModBus gateway, supports

Modbus TCP to RTU, and supports automatic polling. The product adopts industrial-grade standard design to ensure the stability of the equipment in harsh working environments, and the rich indicator lights are used to feedback the different working

states of the equipment.

Product Features

 Stable and reliable industrial design, high-level port protection;

 Abundant LED status indicators to quickly locate the working status of the device;

 Support Phoenix terminal or DC head power supply, DC 8-28V wide voltage input, support reverse polarity protection;

 Support terminal interface ( RS485 /RS422 ) and standard DB9 interface ( RS232 );

 The baud rate supports 2400 ~ 115200 bps, and supports multiple verification methods;

 Support sending of various registration packets and heartbeat packets, such as connection sending M AC , connection sending customization, etc.;

 Support stable and reliable host computer and AT command configuration, independent configuration of four channels does not affect each other;

 Support DNS domain name resolution, domain name resolution server can be configured ;

 Support DHCP to dynamically obtain IP, subnet mask , default gateway, DNS server address;

 Support multiple working modes TCP client, TCP server, UDP client, UDP server, MQTT client, HTTP client ;

 4 -way server mode can be turned on at the same time , supporting 12 clients to dynamically allocate and access, and a single server supports 13 clients to access,  DP server mode that supports memory mode , records the UDP address of the last communication, and uses it as the destination address of the next communication;

 Support a variety of Modbus gateways, which can realize the active reporting of RTU devices, support the mutual conversion of Modbus TCP and Modbus RTU protocols, and can be configured as a storage mode to automatically collect device data, or a multi-host mode of one question and one answer;

 Support MQTT gateway function, fast access to Aliyun and standard MQTT3.1.1 servers (OneNET, Baidu Cloud, Huawei Cloud, etc.);

 Support Modb us data to actively report to TCP transparent transmission server, MQTT server and other servers;

 Support HTTP client mode, use HTTP /1.1 protocol, can be configured as two request methods : G ET and P OST

 can use TCP/IP direct communication or connect communication through " virtual serial port " ;

 Abundant independent LED status indicators, supporting links, network cables, data sending and receiving, etc .;

 Support the host computer to perform firmware upgrade or firmware switch through UDP or serial port ;
