LPRS Preliminary Data Sheet
Easy-Radio ER400TRS Transceiver
Easy-Radio ER400TS-RS 1.3

The
transceiver incorporates Easy-Radio technology to
provide a high performance, simple to use radio
device that can bi-directionally transfer serial data over
a range of up to 250 metres Line Of Sight (LOS).
The transceiver operates on the Pan-European
433MHz frequency band from a 3.6V supply and is housed in a space saving
Single-In-Line (SIL) package. Serial input and output simplify interface to host
systems and the embedded software reduces design and development time significantly.
This data sheet describes the electrical and physical characteristics of the device. Operation of the software
is described in the ‘Easy-Radio Software Guide’, which should be read in conjunction with this data sheet.

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 1) The microcontroller programmes
the functions of the RF transceiver and provides the interface to the host system via a serial input/output. It
also contains programmable EEPROM memory that holds configuration data for the various transceiver-
operating modes. The microcontroller also relieves the host from the intensive demands of searching for
signals within the noise, recovering the received data and transmitting data in a suitable format. A Received
Signal Strength Indicator output can be optionally used to measure received signal levels. The module
connects to a 50-Ohm antenna such as a whip, helical or PCB loop.

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 192 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.
