6.4.1. Representation of Keyboard Newline

The user can choose which characters the converter will send to the server when it receives the terminating
character from the card reader or keypad. In USB Keyboard mode, this terminating character is always a
Carriage Return (CR) 13 in decimal and 0x0D in hexadecimal.
The choices are Carriage Return (0x0D), Line Feed (0x0A) or both Carriage Return plus Line Feed (0x0D,
0x0A).
6.4.2. TCP/IP Configuration
The converter can be configured either as a server or as a client. The factory default setting is for the
converter to be a server of data to a network client. In this mode the Local Port for USB is default configured
to 7777. This is the port the converter will use to communicate with the Client.
6.4.2.1. TCP Server Configuration
In Server mode the converter will quietly wait for USB data to arrive. When data arrives it will inform the
Solution Client which will then poll the converter to retrieve the data. The server will typically continue poll
the converter for remaining data and to keep the network port open.
Note that the converter supports 2 USB connections simultaneously on the same port number. Data from
either USB device will be sent to the same server location.
If the converter is configured as Client, when USB data arrives, it will open a network connection to a
solution server based on the Client Configuration settings. This is the most popular mode of operation
