The Instrutech ITC-16 and ITC-18 interfaces are self-contained, 19” rack-mountable, mains-powered digitiser units with BNC I/O sockets attached to the host computer via a digital interface card and cable. Both the ITC-16 and ITC-18 support 8 analog input channels, 4 analog outputs and 8 digital outputs.

Note. The Instrutech ITC-1600, LIH8+8 and USB-18 are not currently supported by WinEDR.

Software installation

WinEDR uses the Instrutech device interface libraries for the ITC-16/18 family. Details for steps (1)-(3) can be found in the Instrutech Data Acquisition Interface user manual.

1)      Install the Instrutech interface card in an expansion slot.

2)      Attach the ITC-16 or ITC18 unit to the card.

3)      Install the Instrutech Device Driver software supplied with the card (or downloaded from

4)      Reboot the computer.

5)      Run the Instrutech test program installed with the device driver to test whether the software installed OK.

6)      Run WinEDR and select from the main menu

Laboratory Interface

to open the Laboratory Interface Setup dialog box

then select Instrutech ITC-16/18 (New driver) from the laboratory interface options list. Note, on systems with Instrutech’s older device driver software installed, it may be necessary to select either Instrutech ITC-16 (Old Driver) or Instrutech ITC-18 (Old Driver) depending upon which interface unit is installed.

Instrutech ITC-16/18: Troubleshooting

WinEDR requires Instrutech's combined device driver library ITCMM.DLL (released late 2001). It may not work with earlier libraries.
