3.4.4 RS232 CONNECTION
The uPASS Reach reader has an on-board RS232 interface for communication with a
host system or for configuring reader settings.
By default the RS232 interface is connected to the UHF processor. This is required
when using the UHFTOOL software. It is advised to use this tool to configure the
reader. Software developers can find the RS232 communication protocol description
in the firmware manual.
The RS232 interface can also be connected to the TRANSIT compatible processor.
The communication protocol, baud rate, data format and flow control depend upon
the firmware in the TRANSIT compatible processor (e.g. P61, P81 or Q70). See
separate documentation.
