You will find information about the connectable cable cross sections, power consumption
and further technical details in section Technical specifications (Page 293).
RS-485: Connection of the terminating resistor
If you connect a star-shaped network with several dedicated line or dialup network modems
to the serial interface of the TIM then operate the serial interface with the RS-485 standard.
You set the RS-485 standard in the configuration of the TIM. With a network operating
according to RS-485 you also need to activate the cable terminating resistor of the bus cable
in the configuration.
