UART RS422/RS485 Connector (CP22)
The UART RS422/RS485 connector CP22 is a 9-pin, male Sub-D
connector located on the front of the connector panel.
N
The DS1104 supports one serial interface. In RS232 mode the signals
are available from the RS232 connector CP21. In RS422/485 mode the
signals are available from the RS422/485 connector CP22. CP21 and
CP22 are mutually exclusive and cannot be used at the same time.
Pinout Because the pin numbering used for Sub-D connectors is not
standardized, the following figure shows the numbering scheme used
(front view).
C
Do not rely on the numbers written on Sub-D connectors.
For detailed information (I/O circuits, electrical characteristics, etc.) on
the I/O lines terminating at this connector, see Serial Interface on
page 136.
