Installing 505 System Hardware SIMATIC 545/555/575 System Manual
Setting the CPU Dipswitches (continued)
The 545 and 555 CPUs have two communications ports. Both ports are
configured as Data Terminal Equipment (DTE).
SW2 selects Port 1 as either a programming port or a printer port on a
545/555 CPU. Port 1 uses an RS-232/RS-423 signaling protocol and an
RS-232 pinout arrangement with an RS-423 (+5 V) signal level extending
up to 50 feet (15 m). You can use a modem to extend this distance.
• Setting SW2 to the left selects Port 1 as a programming port.
• Setting SW2 to the right selects Port 1 as a printer port.
Figure 3-13 shows the locations of Port 1 and Port 2 on the front of the CPU.

Figure 3-13 545/555 CPU Port Locations
With the 545 and 555 CPUs, your choice of cabling determines whether
Port 2 functions as an RS-232/RS-423 port or as an RS-422/RS-485 port.
Figure 3-13 describes the pinouts required for the various Port 2 options.
If you use RS-422/RS-485 cabling, SW1 on the dipswitch allows you to select
between RS-422 and RS-485. Use SW1 as follows:
• Set SW1 to the left when you use RS-232 or RS-422 cabling.
• Set SW1 to to the right when you use RS-485 cabling. RS-485 uses a
single twisted pair to transmit and receive data between the
programming device and the 545/555 CPU. Multiple CPUs or multiple
programming devices (on this RS-485 link) are not supported and must
not be used.
