Product Description

1-port serial to Ethernet embedded serial device server module


NPM301Z is a high performance embedded serial port to Ethernet module, it supports 1 RS-232, RS-422 or RS-485 to 1 100M Ethernet port.


The module is embedded with network transformer, and it can form a 10Base-T/100Base-TX self-adaptive Ethernet port via adding a RJ45 port. Baud rate of serial port is 300-115200bps. It supports TCP Server, TCP Client, TCP Auto, UDP and Real COM operating mode. It supports maximum 4 TCP connections and domain name access.


All settings of NPM301Z are achieved via serial port or network. It can be used as communication processor between serial device and PC or used for remote communication among multiple serial devices. It can be widely used in PLC control and management, building automation and control, healthcare automation system, measuring instrument and environment dynamic monitoring system.


Features and Benefits

  • Adopt 32 bits ARM processor
  • Support 10/100 Base-T(X) self-adaptive Ethernet port
  • Support AUTO MDI/MDIX, connectable to crossover cable or straight through cable
  • Support 300bps-115200bps line speed non-blocking communication
  • Support low power consumption mode and high performance mode
  • Support TCP Server, TCP Client, TCP Auto, UDP and Real COM driver operating mode
  • Operating port, destination IP address and port can be configured
  • Built-in WEB server, which is convenient for user to conduct webpage configuration
  • Support AT command, which is convenient for the user secondary development
  • Support DNS to meet the requirements of achieving communication via domain name
  • Support virtual serial port drive access mode and automatic connection recovery after network interruption
  • Support flexible serial port data frame segmentation to meet user's demand for message segmentation
  • Support SOCKET operating mode (TCP Server, TCP Client, UDP)
