Product Data Sheet

MULTITONE PAGING SYSTEMSRPT503 UHF - PAGING TRANSMITTERSALES DATA SHEETThe new RPT503 UHF Series Transmitter has been designed specifically to interface with the Multitone pagingsystems. With up to 5 watts of output power and supporting master and slave line synchronization it meets therequirements of even the largest paging systems.Connected by a Single Twisted PairA single pair line cable is all that is required to connect the encoder to the transmitter. This allows local operation via atwisted cable pair, or remote operation via a PTT line. DTMF tones switch the transmitter into different modes, allowingboth analogue and digital data and speech to share the same pair.Multiple Code Formats SupportedThe RPT503 Series Transmitters can be used for Multitone analogue and digital formats, transmitting any analogue,digital or FM (Frequency Modulation) code formats. The RPT 503 transmitters are also able to transmit FSK (FrequencyShift Keyed) formats such as POCSAG (CCIR Radio Paging Code No. 1).Integral Line SynchronisationThe RPT503 Series Transmitter can be synchronised to other transmitters on the same frequency, without therequirement for a separate synchronization unit. The RPT 503 transmitters are linked via an audio-pair line and use lowfrequency tone signaling to synchronise the transmitter frequencies. Status Indication & Fault MonitoringLED’s provide visual indication of the transmitter status. These include; Tx keyed, power and fault. Internal fault conditions are also monitored, such as High Reverse Power and Oscillator Fail. Further features include a failsafe timer,to key down the transmitter automatically after 256 seconds and a phase locked local loop oscillator for consistentperformance and reliability.Easier Installation & SupportTransmitter set-up is configured via a standard PC or Laptop, making the RPT503 UHF Transmitter easy to install and configure on-site. With a small footprint and extremely lightweight design this product is much easier to handle. Suppliedwith both mounting brackets and feet, it can be easily wall or desktop mounted.••Easy selectable power output from 1 to 5 watts••Fully synthesized transmitter from 430MHz to 470MHz••Up to 100 percent duty cycle••Multiple code formats: Multitone Mk6, Mk7 and POCSAG••Easy to install and configure using a standard PC or Laptop••Small footprint
