Installing The Telephony Driver
If this is a first-time installation, skip the next section and go directly to the section titled Installing The New
Telephony Driver.
Removing The Existing Telephony Driver
If you already have a PCIU in service, you must removefrom windows the telephony service provider that the
PCIU was installed with.
To remove an existing PCIU service provider,
1. Click on the Start button in the lower left corner of the screen. Go to Settings and select Control Panel.
2. Double click on the Telephony icon located in the Control Panel dialog.
3. Select the Telephony Drivers tab (Older versions of the Telephony Control Panel may not have this. If you
see a Driver Setup button, click that).
4. Select Comdial PCIU TAPI Service Provider ‘and click Remove. If a message box pops up asking if you
are sure you want to remove it, click Yes.
Installing The New Telephony Driver
After you have physically connected the PCIU to your PC, you must install the floppy disk that contains the SPI
software that runs the PCIU device into the computer's floppy disk drive (drive A).
To install the telephony driver (using Windows95, 98 or NT),
1. Click on the Start button in the lower left corner of the screen and select Run.
2. Type ‘A:SETUP’ at the prompt and click OK.
3. A message box will appear asking you to close any other TAPI applications and services before continuing.
Click OK to continue with the installation. The installation window will display the status as the installation
progresses.
4. If using Windows95, a message box may appear displaying: Current version of TAPI not recent enough….
Install TAPI 2.1 now? If this occurs, click Yes. The service provider installation program will close itself
and run the TAPI 2.1 installation program.
If a message box ever pops up asking: Do you want to keep this file?, click Yes. After TAPI 2.1 is installed,
remove the floppy disk, and click Yes to the prompt that reads: Do you want to restart your computer now?.
The computer will restart and automatically continue with the installation.
5. A dialog window will appear titled Comdial PCIU Service Provider??. Select the appropriate system type
and com port from the drop-down lists.
6. Click the Query Start button.
7. The computer now configures itself according to your telephone’s settings. Do not use your telephone while
the computer is configuring itself.
8. Note that each button that you have mapped to a line has a check box next to it in the Phone Button Usage
section. The system notifies TAPI applications of calls that ring on all lines with checked boxes; therefore,
Comdial engineers recommend that you uncheck all boxes that do not ring at the PCIU station port. When
finished, click OK.
