Signal names in parentheses apply when the UART is set to the RS422
mode. However, you should use the
on page 137 instead, when you are using RS422
mode.
Slave DSP UART RS232 Connector (CP41)
The slave DSP UART RS232 connector (CP41) is a 9-pin male Sub-D
connector located on the front of the connector panel. The pinout
has been adopted from the 9-pin RS232 connector of a PC.
The slave DSP of the DS1103 supports one serial
communication interface. In RS232 mode the signals are
available from the slave DSP UART RS232 connector
(CP41). In RS422 mode the signals are available from the
slave DSP UART RS422 connector (CP43). CP41 and CP43
are mutually exclusive and cannot be used at the same
time.
Objective
Because the pin numbering used for Sub-D connectors is not
standardized, the following figure shows the numbering scheme used
(front view).
Do not rely on the numbers written on Sub-D
connectors.
