The 12-86-5000 is a small, high specification, low cost Paging transmitter PCB measuring 60mm by 31mm and only 6mm deep with battery fitted. The 12-86-5000 has been tested and type approved as a bare PCB, allowing integration into other products without further type approval testing being required. The 1286 range of products are POCSAG direct to pager transmitters, allowing low cost systems to be developed since intermediate receivers and transmitters are not required for short range applications. 12-86 transmitters support up to 5 inputs, each of which can be programmed with up to a 35 character message. Programming can either with a serial programming cable that can be purchased separately or preprogrammed when supplied. A "Flash and Cancel" feature allows the 12-86-5000 to be programmed to flash the red LED for a period of time after each transmission. This allows the originating transmission source to be easily identified. Although the 12-86 is a low power transmitter, a direct line of sight transmission range of up to 200 metres can be expected. Transmit range within buildings is reduced, but still considerable having proven to be effective in some cases between floors and across buildings.
