Auxiliary RS232 Interface
The RS232 auxiliary interface is available for Point-to-Point connections. When it
is connected to the host computer it allows transmission of code data.
The parameters relative to the aux interf
ace (baud rate, data bits, etc.) can be
defined through the Reading Phase step (Channels) in DL.CODE.
The 9-pin female Auxiliary Interface connector inside the CBX is the preferred
co
nnector for temporary communication monitoring.

If permanent system wiring is required, the following pins are used to connect
the RS232 auxiliary interface:
