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 tuned 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.
The USB and RS232 ports can be used to initiate paging transmissions using the Salcom proprietary protocol, Paging Entry Protocol (PET) or Telocator Alphanumeric Protocol (TAP) PG1 protocol. These ports can be used concurrently making it possible to connect a telephone interface unit and still initiate paging transmissions via the USB port.
Four discrete inputs are supported which may be used to initiate relay commands for remote control applications.
For paging applications a different pre-programmed message can be assigned to an input on high and/or low transition. The unit also supports low voltage detection on the power input.
Configuration of the transmitter is performed via the USB port or the serial port using an intuitive Salcom programming application which allows for the setting of all operational parameters.
The 62-12 is housed in an attractive, durable extruded aluminum case with provision on the base plate for wall mounting
