Installing Drivers for IC-102, LIC-102 and USB to Serial Adaptors

Q: Why can’t I see my IC 102, LIC 102, or USB to Serial Adaptor cable when I run my ACR software?

A: The IC 102, LIC 102 and USB to Serial adaptors are USB devices and have drivers that must be installed in the computer in order to allow them to function with the computer. This driver installation process involves two parts:

  1. It installs the components that allow your computer to recognize the cable as a USB device on your system.
  2. It creates a virtual serial (COM) port for your software to communicate through. Windows will assign this virtual COM port based on the available and unused ports in the computer. Typically Windows has 256 ports available. These devices usually are accompanied with a CD that contains the driver.

ACR has several software packages of differing vintage and there may be limits on the COM ports that are accessible through the respective ACR software packages. Most of the installation difficulties encountered will be with the older ACR software packages.

  • TrendReader is the only software that potentially allows access to all 256 COM ports available in Windows. It also has the drivers for IC 102 and LIC 102 contained in the software itself. The software should recognize these cables automatically when plugged in.
  • With EventReader for PowerWatch software, you will need to install the drivers and virtual ports utilizing the CD that comes with the respective interface cables.

You can manually assign COM ports. This process is quite simple to perform. (See “How do I to reassign COM Ports” in the FAQ section.)

*Also note that any software (ACR or otherwise) that opens a serial COM port will prevent access to that port from additional software while it is running. It is usually a good rule of thumb to close any other software that is communicating through a port before launching any ACR software. PDA communication software is usually notorious for running in the background and holding ports open, therefore making the port unavailable to the ACR software.

Q: Why is my IC-102 / LIC-102 connection intermittent in WIN 7, 8 & 10?

A: If you are running WIN 7 it is likely the computer does not like the virtual COM port that the cable uses when it installs. Try switching it over to a purely USB connection. Plug the cable into a USB port, close the TrendReader software and do the following:

  1. Go to Device Manager and see if the ACR IC-102 is listed under Ports COM & LPT. If it is, go to step 2.
  2. In device manager again, under Universal BUS Controllers (at the bottom) the ACR IC-102 should be listed. Right click on it and select Properties.
  3. Click the advanced tab.
  4. Uncheck Load VCP - click OK.
  5. Unplug the cable from the USB port. wait 5 seconds, then plug it in again.
  6. Test the connection now in TrendReader as normal.

You may need to restart the computer (restarting will help to clear things out). Restart TrendReader to make sure the problem has been cleared up.
