Low Power 收发器 with 以太网 - VHF / UHF (20-90)
The 20-90 is a simple to configure POCSAG paging transceiver with a high sensitivity receiver combined with a 100mW transmitter. It operates over the frequency range of 142-175MHz (VHF variant) or 440 479MHz (UHF variant) decoding and encoding 512, 1200或2400波特, alphanumeric or numeric messages.
The 20-90 supports multiple message queueing and will queue up to four 73-character messages or more smaller messages.
The 20-90 Can be controlled via an RS232 serial interface or TCP/IP to provide numeric, alphanumeric and tone only POCSAG encoding.
The product supports full batching of serially queued input messages and can be configured to automatically respond with checksum information of the last received message.
An intelligent self-adjusting channel busy check prevents message collision or corruption.
The receiver is supplied with clean contacts rated at 1A 24V DC operation. LEDs indicate receiver operation and status.
Virtual outputs can be used to remotely trigger input or periodic messages and provide a mechanism to acknowledge reception of messages. It can transmit the received signal strength of the last received message allowing the receiver positioning and system health to be monitored.
