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.
1.
Disconnect the encoder from the Ethernet network before working with the terminal
program.
2.
Connect the serial interface of the encoder using any available serial interface on the
computer.
Configuring the terminal
Before the terminal program can communicate with the encoder, the transmission parameters
must be matched. Make the following settings for the terminal program:
–
19,200 bps
–
8 data bits
