S7-200 Programmable Controller System Manual
The HyperTerminal displays in Figure
7-43 show how to enter the AT
commands. If you do not need to supply
a second AT command at the prompt,
press the ENTER key. This returns you
to the selection for modifying the AT
commands or exiting. If you finished
entering the AT commands select Exit.
After exiting the HyperTerminal
configuration of the RS-232/PPI
Multi-Master cable, disconnect the cable
from the PC and connect it to the
modem. Power cycle both the modem
and the cable. You are now ready to use
the cable for remote operation in a PPI
multi-master network.
Freeport Operation with HyperTerminal
Configuring the RS-232/PPI Multi-Master cable for Freeport operation using HyperTerminal is very
similar to the example configuration described above. Follow the prompts to configure the cable
according to your needs.
