Pocsag Decoder Board
Product Number: W3600(Version 1.0)

Our pocsag decoder board comprises TXCO and high quality components. It is characterized by RS232 data output, synthesized frequency, high receiving sensitivity and high reliability. This product can operate in very demanding environments.

Some countries have no flex paging service but own the pocsag type. Usually the pocsag paging service is for the public and can cover a whole city. In addition, most of small-scale on-site paging services employ the pocsag signal format and they are required to be compatible with the control chips on the other side. The UART interface is employed.
