You may have purchased a software package designed to work in conjunction with the Whozz Calling? unit. The software may have a built-in automatic search and find function. This routine will search all COM and IRQ numbers in an attempt to determine settings for the serial port to which the unit is connected. If an error message indicates that the software cannot communicate or “find’ the unit, you will need to run the Loopback Test below to determine if there exists communication port conflicts within your computer. If your software requires a manual selection of the COM and/or IRQ settings, the Loopback Test is also helpful in determining these parameters.
The unit should be connected to the serial port, placed in a convenient location next to the computer, and your software installed. Permanent installation and phone line connections can be made once communications between the software 6 The unit should be connected to the serial port, placed in a convenient location next to the computer, and your software installed. Permanent installation and phone line connections can be made once communications between the software and hardware is established. Plug in the power to the unit and run the software. Phone lines need not be connected at this time.
Your software will require that you set the COM port number to which the unit is connected. Try different COM numbers to establish communication. If no communication can be established then chances are serial port is not configured correctly or the COM port number and/or IRQ number defined for the serial port conflicts with another device such as an internal FAX/ modem. To determine whether a serial port is configured and working properly use HyperTerminal in Windows and Loopback test procedure on the following page.
Make sure your software program that runs in conjunction with Whozz Calling? is closed.
From your Desktop Select Start and then Run. Type HyperTrm.exe and click "OK"
In the Connection Description dialog box Type: “Test” on the Name line and Select: OK
In the Phone Number dialog box leave phone number blank and Select: Connect using Direct to COMx. Where “x” represents the COM port number being tested (ex. 1,2,3, etc.) Select: OK
In the Properties dialog box Select Bits per second: 9600, Data bits: 8, Parity: None, Stop bits: 1, and Flow Control: None. Then Select: OK
Select: File/Properties. In the Test Properties dialog box select the Settings tab and set Emulation to ANSI. Select ASCII Setup and make sure that Echo typed characters locally box is not checked. Select: OK to close and OK again to close the Test Properties box.
Disconnect the serial cable from the unit, and attach the supplied Loopback Connector to the cable (the other end is connected to the serial port on the PC).
Type any character.
If the character you typed shows on the screen, the serial port is functioning properly, the test is positive.
If you do not see the character COM port and click OK.
Select: Call/Connect and type any character again and repeat above as necessary.
If you obtain a positive result, close HyperTerminal and run the your software again. If not, you may have a conflict between your serial port settings and an internal device such as a FAX/modem. Consult your computer technician to resolve the conflict.
