WedgeLink SM Hardware Wedge
Input Data from any Mitutoyo Gage into your PC Application

The WedgeLink SM is a hardware keyboard wedge that supports Mitutoyo and Mitutoyo compatible gages. With the WedgeLink SM, you can transfer Mitutoyo gage readings into any PC application that accepts keyboard input. Some of the more common applications that are used with the WedgeLink SM include Microsoft Excel, Microsoft Access and Minitab.

About Hardware Wedges
An advantage of a hardware wedge is that it is simpler to use than software wedges because they are more like a plug 'n play device. In most cases, just plug it in and you are ready to go. For information on connecting the hardware wedges to PC's and laptops, see Connecting the WedgeLink SM Hardware Wedge sections on this page.

Key Features of WedgeLink Keyboard Wedges
The default settings on each wedge when received are configured to output the gage measurement plus carriage return. In most cases, that is what the user needs. All features are controlled by an easy-to-use Windows-based setup program so that you can change the default settings if you choose. If you have multiple units to configure, you simply create a configuration file and transfer it into each of the units. Firmware (the software within the wedge) can be easily upgraded by users in the field to allow for software enhancements and customization.

Connect to the PC/laptop via the keyboard input port or to a USB port via the optional USB to PS/2 adapter.
Serial communications test program (ComTestSerial) included to assist in setup and testing.
Can function as a hardware wedge or a Mitutoyo gage interface (the "Dual Personality")

The "Dual Personality" of the WedgeLink SM
Not only is the WedgeLink SM a hardware wedge, it can also function as a Mitutoyo interface. The personality that it uses is selected in the Windows-based setup program. Why is this an advantage? You may have a project this week that requires a keyboard wedge. Next week you could have a project that requires a Mitutoyo gage interface that needs to be used with an application that knows how to read the serial port. WedgeLink SM can do both! This "dual personality" feature is provided at no additional cost to you.

Remember, a hardware wedge is a device that takes Mitutoyo data and sends it out the keyboard cable so that the PC thinks the data was typed in at the keyboard. An interface is a device that takes a Mitutoyo gage reading and sends it to an application via the serial port.

What's Included with the WedgeLink SM Hardware Wedge

WedgeLink SM hardware wedge
6' cable for connecting the WedgeLink HW to your PC (keyboard port or USB to PS/2 adapter)
9-pin serial cable (so that you can send configuration parameters to the wedge)
CD with Windows-based setup program, and ComTestSerial (communications test program)
User's Guide (on the CD as well)
Unlimited technical support

WedgeLink SM Back Panel
The back panel contains a DB9 serial port, a keyboard input port, and a keyboard output cable. Refer to the paragraphs below for the best way to connect your hardware wedge to your PC or laptop.

The DB9 serial port is used for downloading configuration parameters and updating the WedgeLink SM firmware. If you do not have a serial port on your computer, you should also purchase a Serial to USB cable.
The keyboard input port (circular connector in upper right corner) is used if you connect a keyboard directly to the hardware wedge.
The keyboard output cable is connected to the keyboard input port on your PC or to a USB to PS/2 adapter.

Connecting the WedgeLink SM Wedge to Your PC
In the past, in order to connect a hardware keyboard wedge to your PC, you would have to perform the following steps:

Turn off your PC
Unplug the keyboard from the back of your PC
Plug the keyboard into the hardware wedge
Plug the hardware wedge into your PC
Restart your PC

You can still perform all of these steps, but a simpler way to connect your hardware wedge to use a $15 USB to PS/2 adapter:

Plug the USB to PS/2 adapter into a USB port on your PC while your PC is on
Windows will recognize this device and no drivers need to be installed (you may need the installation disk for Windows 98)
Plug the WedgeLink hardware wedge into the USB to PS/2 adapter
That's it!

When using the WedgeLink keyboard wedge, we highly recommend that you connect it using the USB to PS/2 adapter. It allows you to easily connect and disconnect the wedge without having to turn off your PC.

Connecting the WedgeLink SM Wedge to Your Laptop
Many laptops have a connector on the back that looks like a keyboard/mouse port. You can plug either a keyboard or a mouse into this port. You can also plug our hardware wedges into this port; however, since this is not a standard keyboard port, the wedge will not properly function unless a keyboard has also been plugged into the wedge.

The best solution for a laptop is to use the USB to PS/2 adapter described above and plug it into one of the USB ports on your laptop.

Upgrade Options
When firmware upgrades are available, they can be downloaded from our Downloads page. Upgrading the firmware is as simple as connecting the wedge to a serial port on your PC, selecting the serial port number in the firmware update software and pressing the Update Firmware button.
