Abstract

Data transfer devices as well as methods of interfacing, configuring, and using the same are disclosed. Data transfer devices described herein allow a proper communication interface to be mounted on an input device, e.g., a scanner, connected to the data transfer device, enabling communication between the input device and a host device. The data transfer devices allow the input device to be configured for communication with the host device based on a particular type of connection, e.g., a particular hardware attachment that utilizes a particular communication interface. The data transfer device therefore enables “plug-and-play” connectivity between an input device and a host device that removes the amount of user-configuration or user-modification that is required to establish a connection or have the input device, e.g., scanner, mount a proper interface that is compatible with the data transfer device.

First claim

What is claimed is:

1. A data transfer device, comprising:
an adapter component attachable to an input device and to a host device;
a configuration component that stores configuration settings to enable communication with the input device, and
a logic component,
wherein the data transfer device is configured to:
send a plurality of initial communications to the input device,
receive, in response to the plurality of initial communications, an unique communication indicating that a communication channel with the input device is open,
send to the input device the configuration settings used by the data transfer device to communicate with the input device, and
receive an indication that the input device has applied the configuration settings to mount a communication interface between the data transfer device and the input device from a plurality of available communication interfaces stored on the input device.

2. The device of claim 1 , wherein the unique communication comprises a specific data configuration associated with the plurality of initial communications.

3. The device of claim 1 , wherein the communication interface comprises the configuration settings.

4. The device of claim 1 , wherein the configuration settings comprise one or more of baudrate, parity, databits, and start and stop bits.

5. The device of claim 1 , wherein the data transfer device implements one or more levels of a communication protocol associated with the communication interface between the data transfer device and the input device.

6. The device of claim 1 , wherein the data transfer device, following the receipt of the indication that the input device has applied the configuration settings, is further configured to:
send at least one additional configuration communication to the input device, the at least one additional configuration communication comprising one or more another configuration settings; and
receive from the input device an additional indication that the input device has applied the configuration settings to mount the one or more another configuring settings.

7. The device of claim 1 , wherein the adapter component comprises at least one of:
a USB interface,
a Keyboard Wedge PS2 interface,
an RS485 interface,
an IBM46xx interface,
a RS232 interface, and
an Ethernet interface.

8. The device of claim 1 , wherein the communication interface comprises a hardware layer and a software layer between the data transfer device and the input device.

9. The device of claim 1 , wherein the logic component comprises:
at least one processor and at least one memory, or
a field-programmable gate array (FPGA).

10. The device of claim 1 , wherein the input device comprises a scanner configured for scanning machine-readable indicia, and wherein the data transfer device is non-integrally formed with the scanner.

11. The device of claim 10 , wherein the data transfer device, following the receipt of the indication that the input device has applied the configuration settings, is further configured to exchange data with the input device, wherein the data comprises at least scanned label data.

12. A method for interfacing a data transfer device to an input device, the method comprising:
sending, by the data transfer device, a plurality of initial communications to the input device;
receiving, in response to the plurality of initial communications, an unique communication indicating that a communication channel with the input device is open;
sending to the input device configuration settings used by the data transfer device to communicate with the input device; and
receiving an indication that the input device has applied the configuration settings to mount a communication interface between the data transfer device and the input device from a plurality of available communication interfaces stored on the input device.

13. The method of claim 12 , wherein the unique communication comprises a specific data configuration associated with the plurality of initial communications.

14. The method of claim 12 , wherein the configuration settings comprise one or more of baudrate, parity, databits, and start and stop bits.

15. The method of claim 12 , wherein the data transfer device comprises an adapter component attachable to the input device and to a host device, and wherein the adapter component comprises at least one of:
a USB interface,
a Keyboard Wedge PS2 interface,
an RS485 interface,
an IBM46xx interface,
a RS232 interface, and
an Ethernet interface.

16. The method of claim 15 , wherein the input device is a scanner adapted to scan machine-readable indicia, and wherein the data transfer device is connected to the scanner using the adapter component.

17. The method of claim 16 , further comprising, following the receipt of the indication that the input device has applied the configuration settings, exchanging data between the input device and the data transfer device, wherein the data comprises at least scanned label data.

18. A system for a data transfer device to interface with an input device, the system comprising:
a data transfer device configured to send a plurality of initial communications to the input device;
in response to the plurality of initial communications, the data transfer device is configured to receive an unique communication that a communication channel is open with the input device;
the data transfer device is configured to send the configuration settings to the input device to communicate with the input device; and
the data transfer device receives an indication that the input device has applied the configuration settings to mount a communication interface between the data transfer device and the input device from a plurality of available communication interfaces stored on the input device.

19. The system of claim 18 , wherein the data transfer device comprises an adapter component attachable to the input device and to a host device, and wherein the adapter component comprises at least one of:
a USB interface,
a Keyboard Wedge PS2 interface,
an RS485 interface,
an IBM46xx interface,
