Make your entrance access better and more convenient with these 2 and 4-channel Ditec Zen remote controls! These hand-sized transmitters come in several bold colors. From blue, red, yellow, and green to black and white with chrome inserts, vibrance is definitely the new norm. You can also choose between 433.92 MHz and 868.35 MHz operating frequencies, both designed for use in the USA and offer better transmission. Here is another trap; With each transmitter, you can choose your preferred usage codes, which are highly compatible with available Ditec receivers and installations. Some of the codes available include fixed code, which is also compatible with the MM 53200 protocol, Dip Switch, Ditec rolling code with billions of combinations, protected mode, and the new kid in block 128-bit AES encryption mode. There is always something satisfying about the power of choice. You can also configure these remote control transmitters in standard mode through the receiver or by duplicating existing transmitters. And if you want to experiment more, try the ZEN Manager software or the ZENPAD programming unit. So much flexibility in one device, right?
