The Scope Connexions System Connexions System is a modular UHF paging solution designed to provide flexible, reliable on-site paging at a cost-effective price. Its modular design allows the system to expand as your needs evolve, keeping initial investment minimal while supporting robust connectivity to a wide range of host devices.
The system interfaces include internal telephone lines, PC networks, RS232, RS485, USB, dry contacts, and voltage triggers. An optional internal protocol conversion feature enables RS232 data from host hardware—such as fire, intruder, nurse call, or building management systems—to be translated into paging signals, making the system highly versatile. The basic unit comes with two RS232 ports and eight dry-contact inputs, with default configuration supporting up to 4-digit pager numbers (9999), allowing straightforward expansion.
Operating on UHF frequencies, the Connexions System provides high reliability in commercial environments while using compact, unobtrusive aerials. It employs the international standard digital POCSAG signalling system, widely recognised for its sophistication and dependability.
