!
Designed for compliance with EN 300 220-3 and EN 301 489-3
Each transmitter module is pre-programmed and unique
No additional circuitry required to use the module
32-bit encryption 鈥?more than 4 billion combinations
Usable range up to 300m
Available at 433.92MHz
Fully screened module
Suitable for use with a Radiometrix KRX receiver-decoder
!

The module combines full screening with extensive internal filtering for EMC - minimising spurious
radiations and susceptibilities. The KTX2 module will suit wireless control links in applications including
car and building security and secure unidirectional remote process control. Because of the small size and
low power requirement the module is ideal for use in portable, battery-powered devices such as hand-held
remote controls requiring data integrity and high security.
