  • Page 8: Introduction

    PowerTALK 101 Introduction Brief description PowerTALK 101 is an Ethernet-to-Serial Converter that packages serial data into TCP/IP packets that are transmitted through a standard Ethernet port and onto the corporate or industrial network / Intranet / Internet. It simultaneously also does the inverse: TCP/IP packets that are addressed to PowerTALK 101’s IP Address (user definable) is accepted by the device and repackaged into the original stream of serial data and is sent to the appropriate serial port.

    PowerTALK 101 Testing system watchdog PowerTALK 101 has a watchdog system implemented to guard against hardware and/or firmware failure. It is very difficult to test since one needs an actual faulty processor, but can be simulated by the short, as indicated. The short actually forces the PowerTALK 101 unit to not refresh the watchdog timer, resulting in repeated system reset.
