TNPP (Telocator Network Paging Protocol)
TNPP is a point to point digital communications protocol for sending pages from a paging terminal to
another paging terminal, or to a transmitter controller in a paging network. TNPP is ASCII character
oriented which is transmitted via a standard RS-232 asynchronous data port. The data rate can vary
between 300 and 9600 baud and is determined by the application and the data network used.
TAP (Telocator Alphanumeric Protocol)
TAP (also known as PET or IXO protocol) is as a one-way ASCII-based protocol used by a piece of
equipment sending numeric or alphanumeric pages to a single paging terminal, such as an alarm
monitoring system, alphanumeric message entry station, personal computer, PC network, or 3rd party
email or web-based paging software. It typically operates over a serial link either directly using an RS-
232 port, or over a telephone line and modem.
