ASCII Serial Communications Chapter 12
Configure Your Terminal Emulation Software
Personal computers use terminal emulation software to send and interpret
received characters at the EIA-232 serial port. This software allows you to type
letters and numbers to form commands at the computer keyboard and to see the
characters you type and the relay responses on the computer screen. To ensure
the PC communicates correctly with the relay, configure the terminal emulation
software connection properties to match the relay serial port configuration.
Configure the terminal emulation software to match the default settings shown
in Table 96. For the best display, use VT-100 terminal emulation. If VT-100 is
not available, WYSE-100 and ANSI terminal emulations also work.
To change the port settings, use the front-panel
SET/SHOW > PORT settings
menu item.
Serial Port Settings The 825-P provides settings that allow you to configure the communication
parameters for the front-panel serial port. The front-panel serial port supports
only ASCII communications.
