To connect the computing unit to a SIMATIC S5 programmable controller, perform
the following steps:
1. Turn your device off.
2. Plug the connecting cable onto the COM 1 port.
3. Screw the connector tight.
4. Plug the connecting cable into the corresponding port on the CPU of the
programmable controller.
5. In order to enable TTY operation, you must set TTY to “enabled” in the BIOS
setup.
Caution
Danger of damage being caused to the device
If you interchange the connectors, or use wrong connecting cables, the port might
be damaged.
Be careful not to plug the TTY cable in the LPT 1 port of the computing unit
instead of the COM 1/TTY port.
Before inserting the connecting cables, the static charge of your body, the device
and the connecting cables must be brought to the same level. You can do this by
briefly touching the metal housing.
Use only the original connecting cable for the connection to the programmable
controller.
