6 Serial Port Protocols
The
Peoplefinder II
paging transmitter supports three different serial port communication protocols. Each protocol
has its own uses, and the correct one for one application may not be the correct one for another. The
Peoplefinder II
must be configured to support the desired protocol, and only one protocol may be used at a time. The three
protocols supported are:
protocols supported are:
TAP (also called IXO)
The Telocator Access Protocol is an industry standard protocol for
communications between paging entry devices and a paging terminal.
Individual pagers can be sent individual messages.

COMP1
This protocol is a simple way to send data to one pager. It is designed to allow a
person with a simple computer terminal to type a message into the

.
The
Peoplefinder II
must be pre-configured with the CAPCODE of the pager to send
the data to, and all data sent into the serial port of the
Peoplefinder II
will be sent to
that one pager.
COMP2
COMP2 is similar to COMP1, except each page requires two lines of text to be
entered. The first line is the pager number to send the page to, and the second
line is the alpha or numeric message to send to that pager.

line is the alpha or numeric message to send to that pager.
6.1 TAP
The Telocator Alphanumeric Protocol, or TAP protocol as it is called, is used to send pages to communicate
paging information to a transmitter. It is a sequence of characters sent over a serial interface to a transmitter.
The transmitter must parse the commands, and take the appropriate actions.
paging information to a transmitter. It is a sequence of characters sent over a serial interface to a transmitter.
The transmitter must parse the commands, and take the appropriate actions.
The following sections describe how the TAP protocol works. It assumes that the device communicating to the
Peoplefinder II
Station is directly connected to it via a serial cable. If other means are used (i.e. modem) then the
modem connection must first be established. For the purposes of this manual, the
Peoplefinder II
is assumed to be
the transmitter, and the device connected to its serial port is the "Entry Device". Typical entry devices are
computers, paging terminals, and alarm monitors. Characters listed in brackets <xx> are ASCII codes, and the
values for them are listed at the end of this document.
