BIM-4xx-RPC Parallel Interface Transceiver Module
The RPC is a self-contained plug-on radio port which requires only a simple antenna, 5V supply and a byte-wide
I/O port on a host microcontroller (or bi-directional PC port). The module provides all the RF circuits and
processor intensive low level packet formatting and packet recovery functions required to inter-connect any
number of microcontrollers in a radio network.
A data packet of 1 to 27 bytes downloaded by a Host microcontroller into the RPC's packet buffer is transmitted
by the RPC's transceiver and will "appear" in the receive buffer of all the RPC's within radio range.
A data packet received by the RPC's transceiver is decoded, stored in a packet buffer and the Host
microcontroller signalled that a valid packet is waiting to be uploaded.
FEATURES
• SAW Controlled FM transmitter
• Superhet receiver
• Built-in self test / diagnostics / status LED’s
• Single 5V supply @ < 20mA
• 40Kbit/sec half duplex
• Free format packets of 1-27 bytes
• Collision avoidance (listen before transmit)
• Direct interface to 5V CMOS logic
• Power save mode
• 418MHz and 433MHz versions
• 1mW and 10mW versions
• Packet framing and error checking are user
transparent

ground
The RPC accepts its data as parallel 5V TTL logic level nibbles making it compatible with all microprocessor
technologies. The RPC can be used to set up communication links between computers via bi-directional
parallel communication ports.
