EW N Issue 1, 05 March 2008 Radiometrix Hartcran House, 231 Kenton Lane, Harrow, HA3 8RP, England Tel: +44 (0) 20 8909 9595, Fax: +44 (0) 20 8909 2233 KTX2 UHF FM Code-Hopping Data Transmitter Module The KTX2 is a miniature PCB mounting code-hopping UHF radio transmitter suitable for use in secure remote keyless control applications at distances up to 75 metres inbuilding or 300 metres open ground. Figure 1: KTX2-433 Features Features ! ! ! ! ! ! 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 – 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. Technical Summary ! ! ! ! ! ! Crystal-locked PLL FM data with Manchester encoding Operation from 3V to 6V +3dBm output on 433.92MHz 0.55Vcc – Vcc) to cause a transmission. S1 (pin 6) Input (1) – activate high (>0.55Vcc – Vcc) to cause a transmission. S2 (pin 7) Input (2) – activate high (>0.55Vcc – Vcc) to cause a transmission. S3 (pin 8) Input (3) – activate high (>0.55Vcc – Vcc) to cause a transmission. Internal Use (pin 9) Modulation (Data). This pin is connected to the modulation input of the Transmitter, therefore do not connect anything to this pin during operation of the module.

Single message time is typically 150ms. Whilst S0 – S3 are all deactivated (low) standby current consumption is
