WedgeLink Keyboard Wedges: Your instrument's readings, typed right where you need them

Connect a scale, force tester, DRO or any RS-232 instrument to a WedgeLink and each reading is typed wherever the cursor is: Excel, SPC software, an ERP screen or a web form. The WedgeLink AT keeps just the number you need, and in Excel it can add the date and time.

How WedgeLink works: an RS-232 instrument such as a bench scale, force tester or digital readout sends each reading over its RS-232 cable to a WedgeLink AT. The AT keeps the part of the reading you need (for example just the number, without status codes, spaces or units), can split values into columns, and adds the date and time in Excel. It types the clean value over USB into Excel, SPC software or a web form.

In this setup: WedgeLink AT, DB9 cable for the scale.

For each one the configurator suggests a cable, gives the serial settings where MicroRidge has them, and writes out every setup step. When the exact wiring is not on file it adds the DB9 Adapter Kit, and AutoBaud learns any missing settings.

AutoBaudThe AT finds the instrument's serial settings, 600 to 57,600 baud

Press the AT's Reset button, then the instrument's print button, and it learns the baud rate and format: 600 to 57,600 baud, none, even or odd parity, 7 or 8 data bits.

ParsingKeep the number, add units, split fields into cells, and add date and time in Excel

Remove characters by type, replace characters, and use up to three parse groups to keep the number, round it, add text before or after, split values into columns, or keep only the lines you want. Date and time stamps work in Excel.

No driversTypes like a USB keyboard into any program

In use there is nothing to install: the computer sees a USB keyboard. Setting the AT up is done once on a Windows PC, with the WedgeLink AT Setup program and its USB driver.

COM portOr works as a serial port for software that reads one

Plugged in by its RS-232 & Prog port, the AT shows up as a COM port and sends the parsed reading at 9600-N-8-1, whatever the instrument's own baud rate.
