ERx00TRS-02 Transceiver Description
The Easy-Radio Transceiver is a complete sub-system that combines a high performance very low power RF
transceiver, a microcontroller and a voltage regulator (Figure 7).

Figure 7 Easy-Radio Transceiver Block Diagram
The Serial Data Input and Serial Data Output operate at the standard 19,200 Baud and the two handshake
lines provide optional flow control to and from the host. The Easy-Radio Transceiver can accept and transmit
up to 180 bytes of data, which it buffers internally before transmitting in an efficient over-air code format.
Any other Easy-Radio Transceiver within range that ‘hears’ the transmission will decode the message and
place the recovered data within a receive buffer that can then be unloaded to the receiving host for
processing and interpretation. Transmission and reception are bi-directional half duplex i.e. transmit OR
receive but not simultaneously.
