Paging
Transmitters
11-43 Personal POCSAG Paging Encoder /
Transmitter
 |
A compact hand-held 4 button,
80mW paging message transmitter. Suitable for personal and commercial security, medical
alert, remote machinery control and many other applications. One of four user definable
paging messages can be sent to a pocket pager or any other type of POCSAG paging receiver.
Each message can be tone only, numeric or alphanumeric, and can be programmed to be
repeated automatically from 1 to 99 times.
Supplied complete with a
replaceable 12 volt alkaline battery, giving an operation life of approximately 300
messages, and an internal aerial. The band of operation is 138 to 174MHz.

 |
Compact 4 or 8 buttons
transmitters suitable for a variety of applications. Each button
can be programmed for sending Tone, Numeric and Alphanumeric messages to
a designated pager or pagers. Also suitable for remote controlling
for commercial and industrial applications.
The 11-93
is same as the 11-92, although 11-93 is
supplied with external antenna for wider range transmission.
Suitable for personal use, commercial security, medical alert,
restaurants, supermarkets, schools, remote machinery control are some of
the applications for these transmitters.

12-62 PAGING TRANSMITTER POCSAG VHF & UHF
|
 |
The 12-62 series transmitters are available as VHF and UHF units with
user-programmable power outputs ranging from 50 milliwatts to 4 watts.
Using programming software, each model can be programmed across its full
frequency range with no hardware adjustments. They are capable of
operating as NRZ or POCSAG transmitters. The built-in POCSAG
encoder can be enabled or disabled as required.
In addition to a
direct/RS232 buffered serial port, an on-board USB port enhances the
range of applications to which the transmitter can be applied.
Input/Output expansion is also possible via an internal plug-in adapter
or an external I/O expansion module, 12-32.
The 12-62 is
housed in an attractive, durable extruded aluminium case with provision
on the base plate for wall mounting.
