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.
