TR2M
Issue 2, 31 March 2015
Narrow Band FM Multi-channel UHF Transceiver
UK Version: TR2M-458-5, TR2I-458-5 (100mW)
European version: TR2M-433-5, TR2I-433-5 (10mW)
The TR2M transceiver module offers a low power,
reliable data link in an industry-standard pin out and
footprint. This makes the TR2M ideally suited to those
low power applications where existing wideband
modules have insufficient range, or where multi-channel
operation is needed. Two versions are available,
covering the 458.5-459.1MHz UK band (at 100mW) and
the European 433.05-434.79MHz band (at 10mW).

RF Level (dBm)
Figure 5: RSSI voltage variation with respect to RF level at TR2M
If the microcontroller has a built-in Analogue to Digital Converter (ADC), the Received Signal Strength
Indicator (RSSI) output voltage level can be read by the microcontroller to estimate its distance from
transmitting TR2M unit or identify areas of weak signal reception.
RSSI can also be used to make a decision to switch to the second antenna in fixed installations within
building where the probability of null-spots are higher.
Regulatory Restrictions
There is a generic 10% duty cycle restriction on the 433MHz ISM band through out European countries with
few exceptions. Annex 1 Band E, Band E2 of European Radio Communications Committee (ERC)
Recommendation 70-03 dated February 2004 specifies the following:
433.050MHz (Ch0)
434.050MHz (Ch40)
10mW ERP, 10% duty cycle
for Channelised Narrow Band and Wide Band usage
433.775MHz (Ch69)
10mW ERP, 100% duty cycle
for <25kHz Channelised Narrow Band usage
433.05MHz
434.040MHz
434.79MHz
433.050-434.790 MHz, Non Specific Short Range Device, band is primarily intended for Telemetry,
Telecommand, Alarms, Data in general and other similar applications. Audio and Voice signals should be
avoided in the band.
