Communication with terminal program

Data terminal
If the encoder cannot be found in the network or the connection to the network is
interrupted, you can connect a data terminal to the encoder for initial setup and setting of
important parameters. The data terminal consists of a computer with a terminal program.
You require a serial transmission cable with a 9-pin Sub-D plug to connect to the computer
and open ends for connection to the terminal block of the encoder (see Section Pin
assignment serial interface, page 95).
HyperTerminal, a communications accessory included with Microsoft Windows, can be used
as the terminal program.
NOTICE!
Information on installing and using HyperTerminal can be found in the manuals or in the online
help for Microsoft Windows.
