2.7.3 Auxiliary RS232 interface
The auxiliary serial interface is used exclusively for RS232 point-to-point
connections.
The parameters relative to the auxiliary interface (baud rate, data bits, etc.) as well
as particular operating modes, such as local echo, can be defined using the
LDHOST utility program or Host Mode programming. For more details refer to
section 2.9 and to the section "Auxiliary Interface Menu" in the LDHOST Help
Online.
The following pins of the 25-pin connector are used to connect the RS232 auxiliary
interface:

RTS/CTS HARDWARE HANDSHAKING ENABLED
Figure 2.22 - RS232 auxiliary interface connections
The RTSAUX and CTSAUX signals control data transmission and synchronize the
connected devices. If the RTS/CTS handshaking protocol is enabled, the LazerData
12000 Scanner activates the RTSAUX output to indicate a message is to be
transmitted. The receiving unit activates the CTSAUX input to enable the
transmission.
