DESCRIPTION

The Linx CMD-KEY#-xxx Remote Command

Keyfob is ideal for general-purpose remote

control and command applications. This unit

has been pre-certified for FCC Part 15,

Industry Canada, and CE (433MHz only)

compliance, reducing development costs and

time to market. Available in 315, 418, or

433.92MHz (418MHz standard), this stylish

and compact remote has a range of up to

1,000ft when combined with the LR Series

receiver. The keyfob can be configured with

1 to 5 buttons and the keypad and labeling

can be modified to meet specific customer

requirements. Selectable addressing

provides security and allows the creation of

up to 1024 distinct transmitter-receiver

relationships. The keyfob is available in

black, white, or transparent colors. The

transmission can be decoded using a

matching Linx Function Module, KH Series

receiver/decoder, or an LC or LR Series

receiver paired with a decoder IC or

microcontroller. The unit operates from a

single 3V CR-2032 lithium button cell.
