12-86-0000
Keyring Pocsag Transmitters
UHF, single
or 4 button low power key ring or pendant transmitter each button
programmable to send Numeric or Alphanumeric message up to 200 meters
depending environment. Ideally suited for short range transmissions
e.g., shops, home, emergency applications etc. It can also be used for
any general remote control applications, e.g., turning lights
ON/OFF, disabling alarms etc
Supplied with
standard CR302 coin cell battery. Transmitter will operate for more then
1000 transmissions under normal conditions before
needing replacement

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.
