Section 3.2.1
RS232 Data Ports
The serial terminal includes a single EIA/TIA RS232 compliant port, consisting of three terminals: Transmit (Tx),
Receive (Rx) and Common (COM).
IMPORTANT!
The RS232 port is intended for point-to-point applications only.
In adherence to the EIA/TIA guidelines for RS232 communications, the following is recommended by Siemens:
• Always use shielded cabling to minimize the effects of ambient electrical noise
• Although greater distances are possible, limit the cable length to 15 m (49 ft) or less for more reliable
communications
• Use a baud rate of 120 kbps
The RS232 port uses a Phoenix-style DB9 compression connector. The following is the pin-out for the connector:
