Note
If the TIM sends or receives data over its external modem interface, this is not indicated by
the TXD and RXD LEDs of the TIM. In this case, the LEDs of the external modem provide
information about the current send and receive activities of the external interface.

Pinout of the X1 and X2 connectors

The X1 connector is designed as a 9-pin D-sub miniature male connector. The pinout is
shown in the following table. As an RS-232 port, the pinout corresponds to that of a
standardized PC connector.
The connector can be configured either as an RS-232 or as an RS-485 port using the 8-pin
DIL switch available from above through the grill in the housing.
