Overview

EM-32S Series TCP / IP components are the industry's smallest embedded TCP / IP protocol serial device servers, serial devices to your network immediately. EM-32S volume compact, 28 x 28 mm size is only equivalent to a QFP208 foot chip core size, the use of single-hole chip stamp pad, single 3.3V power supply, a very small PCB footprint, you can easily the EM-32S as a component integrated with your serial device, so that your serial devices to the 10/100M speed networking.

Built-in TCP / IP communication protocol

EM-32S built-in TCP / IP communication protocol for R & D engineers can easily be networked serial devices, no longer need to spend a lot of time and effort writing TCP / IP communication protocol. In this way, engineers can use most of the time in the development of other more important features, so that the company launched the product cycles. 10/100M auto-detect the interface so that you can enjoy the advantages of high-speed transmission, Auto MDI/MDIX feature allows the network cable straight through, crossover cable may work. In addition, EM-32S has two physical UART serial port, so you have more space, more flexibility to develop products according to customer demand function. EM-32S standard 3.3V power supply, I / O port 5 V-tolerant design is better suited for today's equipment, R & D engineers can spend less time and energy in the circuit design.

User-friendly design options

through easy-to-use windows program ezConfig or Web browser to complete the setup, plug and play.

Shorten product launch schedule

EM-32S with a standard pin spacing (2.54mm) and 32 pin (just a double with one serial port 16 pin) hole or optional stamp design makes its as a TCP component, allowing you to reduce the design cycle, so that products can quickly introduce. In addition, we provide a virtual serial port program, which automatically configure the serial port parameters, the user can not modify the application immediately to achieve network control.

Application

• Access / Security control systems (card readers, biometric identification devices)
• Medical / Healthcare (ECG, ultrasonic detector, blood testing devices)
• Industrial automation (PLC, test equipment)
• Telecommunications room (RTU) control, tank liquid level (CTU) detection
• POS network consumption, LED screen control
• Building automation control systems (HVAC, fire alarms)
• Information appliances (UPS monitoring module)
