This device is ESD sensitive. Do not operate or store near strong electrostatic fields. Use appropriate ESD
precautions.
Note 1: Exceeding the absolute maximum ratings may damage the device.
Note 2: The device is not guaranteed to function outside its operating ratings.
Note 3: The device uses one A23 12 volt battery.
Encoder Types:
Inc.’s proprietary code. This code sends asynchronous data packets with a header and several bytes
of data.
serial number and 6 information bits to create a 66-bit transmission stream. The length of the transmis-
sion eliminates the threat of code scanning, and the code hopping mechanism makes each transmission
unique, thus rendering code capture and re-send schemes useless.

Three encoder types are offered for the HHTX-102: RI, Keeloq, and Holtek. RI is Radios,
Keeloq uses a 32-bit hopping code generated by a non-linear encryption algorithm, with a 28-bit
Holtek uses a Holtek series encoder to securely encode the data being sent.
