The Whozz Calling? POS reports telephone line number and Caller ID information. Caller ID information consists of date, time, caller’s number and caller’s name (if sent). This information is sent via serial stream to any serial device such as a printer or a computer immediately after Caller ID data is captured. Data can be sent at either 9600 or 1200 Baud. Two different formats are available. The CallerID.com format conforms with all other Whozz Calling? products. The limited format matches the TCI, MLX series format. If multiple units are to be connected together, each individual unit can be set for different line numbers. All options, formats, and addresses are set using DIP switches located on the front panel of the unit.
