    Chapter 2: Application Examples View of ETU01-A Terminal Mode via telnet connection and STE-10. 2.2 Terminal Server Application Terminal Server, allows Telnet connection via serial terminal. Refer to the configuration setup for terminal server mode starting in Section 1.7.
  • Page 29 Chapter 2: Application Examples The STE-10 is assigned an IP address for the domain and the serial port is configured according to the requirements of the serial terminal. In our example, we used a PC with Windows®, running HyperTerminal™ and a serial connection on COM1. The port settings were 9600, 8 bits, no parity, one stop bit, and no flow control.

    Auto Telnet and Raw Mode Access provides transparent connection. The right side STE-10 unit is configured in Raw Mode, set an IP address and port number, with serial port configured for the ETU01-A (9600,8,N,1 no handshaking). The left side STE-10 Terminal Server is configured in auto Telnet mode, pointing to the right side's IP address and port number.
