Refer to Figure 2.1, “Front and Back Views of Whozz Calling? 4 Line Model” when connecting unit.
Plug in the power supply and make sure the red Power LED is on.
Connect the supplied 9 pin cable to the female serial connector on unit marked “To Computer”.
Connect the same cable to an available serial port on the computer.
Plug in up to four phone lines into the input jacks marked "IN" on the unit.
Use any terminal emulation program or modem software set to terminal mode.
Set communication parameters to 9600 Baud, 8 Bit, 1 Stop, No Parity.
When turned on for the first time, the unit is set to communicate at 9600 Baud, 8 Bit, 1 Stop, No Parity. All setup toggles are set to their upper case values, but they can be changed later. The order of how the toggles are input or displayed is not important. They are stored in non-volatile memory so that if the unit loses power, the toggles will remain set. To display the toggle settings at any time use the "V" command. On start-up, the "V" command will display:
Vx.x ECXUDASOBKT L=01 00/00 00:00:nn
Where Vx.x is the version number of the firmware, ECXUDASOBKT are the setup toggles, L=01 represents line
number to which the first port of the unit is set, 00/00 is the date, and 00:00:nn is the time of the internal time clock
(in HH:MM:SS).
For simple Caller ID applications, we suggest the following toggle setup:
ECXUDaSOBKT
The combination of a lower case "a" and an upper case "S" instructs the unit to send call information only at the start of each call. With upper case "O" set, the unit will not report call information on outbound calls. This combination of toggles gives the simplest configuration for Caller ID only applications. The toggles can be configured in either upper or lower case and combinations set to support various applications such as Call Accounting, Integrated Voice Response (IVR) applications, Modem/Telephone Security, and Telephony Diagnostics.
All toggles can be changed by simply typing the new toggle. The unit is designed to accept one toggle at a time. If a software application sends an initialization string of toggles to the unit, a short pause of at least 50 milliseconds should be inserted between each toggle so the unit it has enough time to write the entry to non-volatile memory.
