Pinout of the ports
RS-232/RS-485 interfaces
The plugs for the two serial ports are designed as a 9-pin D-sub miniature connectors
(male). The pinout of the two connectors is identical and is shown in the following table. As
an RS-232 port, the pinout corresponds to that of a standardized PC connector.
This is a combined RS-232/RS-485 port. As default, the ports are set to RS-232. The
switchover to RS-485 is set in the STEP 7 configuration and is therefore part of the
configuration data of the TIM 4R-IE DNP3.
