KTX2

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.

The KTX2 transmitter module is a crystal based PLL controlled FM code-hopping transmitter with a preprogrammed Electronic Serial Number (ESN), operating between 3V and 6V supply, at 433.92MHz.

KTX2 is designed to meet or exceed EN 300 220-3 standards for European use and delivers nominally +3dBm at 8mA (for 5V supply). The module measures 36.2 x 15.2 x 4.5 mm.

The module is very easy to use: there are no modulation input or transmitter-enable pins. The activation of any combination of the four function lines (S0 S3) causes a data transmission, part of which is the status of S0 S3, i.e. the function code. In this way, up to 15 different control combinations can be sent from one module. Simple pushbuttons can be connected directly between S0 S3 and Vcc if desired. The module KTX2 will transmit repeatedly whilst any of the function lines is held high for up to 30 seconds (approx.), when a power-saving time-out feature is activated.
