Bitwritter?

DEI has been buying up brand names for years, incorporating the technology they can use and eliminating the brands that would over-saturate any give market with brand names. Now they are streamlining the production lines by using 1 brain for 4 different models in every brand. Viper has a Alarm R/S brain that is 1-way 2-way LE,LC3,HD, same antenna for all 4 models and is also used for Pyhton, Clifford. That's 12 different models across the 3 brands all using the same brain. So far Avital is using the lower line DEI brains with the 6 pin main plug and the Non SST responder antenna. Limiting the 1 mile range to the premuim brands.
