Introduction of M4 Series Serial Device Server

USR M4 Series serial device server is a device to realize data transparent transmission between TCP/UDP data package and UART/RS232/RS485 interface. M4 Series serial device server, embedded with Cortex-M4 kernel, has the features of low power, rapid speed and stable transmission.

Compared with E45 Series, memory capacity, operation speed and available resources of M4 Series serial device server has been increased by double. Meanwhile, its running power consumption is significantly reduced. And full load working current is only 120mA under the rated voltage of 3.3V.

M4 Series serial device server is internally integrated with TCP/IP protocol. Users can easily use it to complete network function of embedded devices, which can make their secondary development products enter the market earlier and enhance competitiveness of their products.

M4 Series serial device has suffered all kinds of harsh environment test. And it has been successfully applied in bank network, highway network, large corporate network and complex network environment formed by turning optical fiber to Ethernet.

Function Upgrading of M4 Series Serial Device Server

  1. Faster operation speed and basic frequency up to 120MHz
  2. Flash space increases to 512K
  3. RAM space increases to 256K
  4. Lower power : 120mA/3.3V
  5. Smaller size
  6. Install lampholder for indicator light to to avoid instruction deviation in the production and use
