What IR keyboard frequency will work with Amino STBs?

The answer depends on the Amino STBs model number. The older Amino 110s use IR frequency (56K), while the newer Amino models (A125, A130 and A130H) use IR frequency (38K). Older IR keyboards (part number 002-455, as displayed on bottom sticker) are locked into a single frequency (56K) and can only communicate with AmiNet110s. Newer IR keyboards (part number 502-455) have a switch in the battery compartment which allows them to be switched between IR frequencies (38K or 56K), allowing them to work with any Amino STB model number.
