EZP-250(A) / Embedded Serial to PPP Converter

EZP-250(A) is a serial to PPP module for manufacturers who want to quickly and easily embed PPP connectivity in their products. This very compact module helps your devices get PPP connectivity with just serial connection through 2G, TRS or Dial-up network. Applying this module, not only you can reduce cost and risk, but also you can shorten development time to add the network capability. Because EZP-250(A) allows you to overcome a distance limitation of your serial communication system, you are able to remotely control and monitor the serial device over the Internet.
