AUXILIARY RS232 INTERFACE
The RS232 auxiliary interface is available for Point-to-Point connections. When it is con-
nected to the host computer it allows transmission of code data.
The parameters relative to the aux interface (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 connector
for temporary communication monitoring.

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