ASR550 Operational Manual
4.3.2 Settings
The file menu “Settings” contains the menu items “Connection”, “Device” and Log File”.
4.3.2.1 Connection
If you press “Connection” an additional window opens. Here you have to select the interface
type and the corresponding settings.
In case of using the readers RS232 or RS485 interface, or the optional Bluetooth Module, the
connection type to be used is “Serial”. This also applies to all kind of USB-Serial-Converters like
an USB-RS232 Converter.
Please select the correct Port Name and the correct baud rate. The baud rate is configurable
between 9600 and 115200 baud. The configured baud rate of the ASR550 has to match with
the selected baud rate of the PC-Software – otherwise the communication will not work. Per
factory default, the ASR550s baud rate is set to 9600.
If the connection was established successfully, the orange circle in the main screen will turn into
green. In addition you can see the currently selected port, baud rate, and the network address,
the PC-Demo Software will use for communicating with the reader.
The default network address is 255 (FF in hexadecimal) which means, all readers listening on
this port will answer requests. Network addresses make only sense in case of having several
readers connected to one RS485 interface.
Please keep in mind that each comport can only be accessed by one program. If
you want to use other software for communicating with the reader, please close
ASR PC-Demo before or at least click on “Disconnect” in the main window.
TCP/IP connections are only intended to be used if your ASR550 has an optional Wi-Fi – or
Ethernet module. Please see the corresponding manuals regarding details about the TCP/IP
configuration.
