TX2M/RX2M
UHF Narrow Band FM multi channel radio modules
UK Version: TX2M-458-5/RX2M-458-5 (100mW)
European version: TX2M-433-5/RX2M-433-5 (10mW)
The TX2M transmitter and RX2M receiver modules
offer a low power, reliable data link in an industry-
standard pin out and footprint. This makes the
TX2M/RX2M pair 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.
TX2I-458-5 transmitter
Features
433MHz version conforms to EN 300 220-3 and EN 301 489-3
and 458MHz version to MPT 1329 (UK specs)
Any custom band between 420MHz and 480MHz with 5MHz (AR0) frequency range
High performance double superhet, 128 channel PLL synthesizer with TCXO
Data rates up to 5 kbps for standard module
Usable range over 1km
Fully screened. Low profile
Feature-rich interface (RSSI, automatic noise squelch, analogue and digital baseband)
Incorporate a 1200baud dumb modem
Re-programmable via RS232 interface
Low power requirements
Applications
Handheld terminals
EPOS equipment, barcode scanners
Data loggers
Industrial telemetry and telecommand
In-building environmental monitoring and control
High-end security and fire alarms
Vehicle data up/download

Transmitter enable. Low = ON, open = off. 4k7 internal pullup to Vcc
DC coupled input for 3-12V CMOS logic. Leave open if unused
AC coupled Analogue Input. Limit to 1Vpk-pk ±10% to keep distortion
<1.5% and peak FM deviation >2.5kHz
DC supply. 75mA maximum drain. Only present when TXE is low
Serial programming/configuration input at RS232 level
Ground
Parallel frequency select inputs. Inverted logic, 10k pullups to 4V

NOTES:
1. Internal AF Input gain is factory set for 1Vpk-pk to produce 3kHz peak deviation and minimum
distortion. Analogue gain may be set for an input level of 50mV – 2V pk-pk. This cannot be done
without appropriate test equipment. Contact factory for details
2. Carrier detect on RX2M mutes the AF and DATA outputs when RF input signal is <-123dBm.
This can be factory disabled if required.
3. There are no pullups on the open collector outputs. External pull-up resistor should be used.
4. With 1200baud modem mode enabled, parallel selection of channel is unavailable as the P1-P3 lines
are used for input/output operations.

Pin description of TX2M/RX2M with Modem mode selected
The 'modem' mentioned is a 1200 baud RS232 semi-intelligent unit (Transmitter is enabled when valid
serial data is present, so no separate Transmit Enable control is needed. Coding in the data stream also
permits the receiver to ignore noise and only output valid serial data.
