ER400TRS Transceiver Description
The Easy-Radio 400 Transceiver is a complete sub-system that combines a high performance very low
power RF transceiver, a microcontroller and a voltage regulator (Figure 7).
.
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 128 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.
