MULTITONE PAGING SYSTEMS
RPT503 UHF - PAGING TRANSMITTER
SALES DATA SHEET
The new RPT503 UHF Series Transmitter has been designed specifically to interface with the Multitone paging
systems. With up to 5 watts of output power and supporting master and slave line synchronization it meets the
requirements of even the largest paging systems.
Connected by a Single Twisted Pair
A single pair line cable is all that is required to connect the encoder to the transmitter. This allows local operation via a
twisted cable pair, or remote operation via a PTT line. DTMF tones switch the transmitter into different modes, allowing
both analogue and digital data and speech to share the same pair.
Multiple Code Formats Supported
The 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 (Frequency
Shift Keyed) formats such as POCSAG (CCIR Radio Paging Code No. 1).
Integral Line Synchronisation
The RPT503 Series Transmitter can be synchronised to other transmitters on the same frequency, without the
requirement for a separate synchronization unit. The RPT 503 transmitters are linked via an audio-pair line and use low
frequency tone signaling to synchronise the transmitter frequencies.
Status Indication & Fault Monitoring
LED’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 consistent
performance and reliability.
Easier Installation & Support
Transmitter 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. Supplied
with both mounting brackets and feet, it can be easily wall or desktop mounted.
