Hardware/Software Keyboard Wedges

Hardware Keyboard Wedges

The primary advantage of a hardware wedge is that it is simpler to use because it is more like a plug 'n play device. In most cases, just plug it in and you are ready to go. The Data-Link HW is a hardware keyboard wedge that accepts input from any RS232 device. With the Data-Link HW, you can transfer RS232 data into any PC application that accepts keyboard input. Some of the more common applications include Microsoft Excel, Microsoft Access and Minitab. The Data-Link SW is a software keyboard wedge that also accepts input from any RS232 device. With the Data-Link SW, you can transfer RS232 data into any PC application that accepts keyboard input. Some of the more common applications include Microsoft Excel, Microsoft Access and Minitab.

HARDWARE Features / DLHW:
  • Supports any RS232 device.
  • Specify rules for defining the input packet (end-of-packet character, gap time or send immediately).
  • Remove unwanted characters from the input packet.
  • Extract the first numeric field from the input packet.
  • Single and continuous read modes.
  • Initiate readings with the read switch on the unit, an optional remote read switch or a send button on the serial device.
  • Works with serial devices that send continuously.
  • Define different commands for each read switch.
  • LED to indicate when RS232 data has been received.
  • Simple to use Windows setup program to define the software operation.
  • Define prefix and/or suffix strings to be included with the wedge output.
  • Specify the end-of-packet character to be sent with each data packet.
  • All power is obtained from the keyboard cable, no separate AC adapter is required.
  • Connect to the PC/laptop via the keyboard input port or to a USB port via an optional USB to PS/2 adapter.
  • Serial communications test program included to assist in setup and testing.
Software Wedges:
    SOFTWARE DATA-LINK A
  • If the data format coming from your serial device is exactly what you want to send to your target application (i.e., you do not need data parsing).
  • You are looking for an economical solution for transferring properly formatted serial port data directly into Windows applications.
  • SOFTWARE DATA-LINK B
  • If the data format coming from your serial device needs to be modified before sending the data to your target application (i.e., you need data parsing).
  • You need to log date and time with the date collected. This software can automatically add the date and time for every data packet received from the serial device.
  • Many serial devices output extra information such as units (pounds, inches, etc.) and you need to remove the units fields before sending the data to your target application.
SOFTWARE Features / DLSW
    Serial Communications
  • You can have 2 serial devices connected simultaneously.
  • If your computer does not have any physical serial ports, you can easily add 1 or more serial ports with a USB to serial cable.
  • Separate parsing schemes can be set up for the data coming from each serial port.
  • Data Parsing (DATA-LINK B only)
  • 5 independent parsing schemes can be created.
  • You can specify which input port the scheme will be applied to.
  • If a packet contains a unique string, You can select the parsing scheme to be applied to this packet based on the unique string.
  • DDE
  • A more effective way of transferring data to Microsoft Excel.
  • Allows the software to maintain the focus so that it is easier to use the built in command buttons and hot keys to send commands to your serial device(s).
  • Send Commands
  • You can specify up to 100 commands.
  • You can specify which port(s) are to receive the commands.
  • 6 commands can be assigned to the command button on the main window.
  • 7 hot keys can be assigned to any of your commands (F2 to F8).
  • Specify number of times the command will be repeated.
  • Specify delays within commands.
