JP1 Remote Controls
All JP1 remotes are made by Universal Electronics, Inc. UEI sells various models under their One For All brand name, and supplies remotes to consumer electronic manufacturers such as Radio Shack, Sony, and Sky, as well as North American cable TV providers such as Comcast, Rogers, Cox, Shaw, Charter and Time Warner.
On printed circuit boards the marking "JP1" is a common abbreviation of "Jumper 1", i.e. the first (and for most remotes, the only) jumper on the board. Perhaps in recognition of this custom, later models are labeled "JP1.x", where "x" is 1, 2, or 3, depending on the type of processor used.
Earlier JP1 circuit board designs employ an EEPROM memory chip. Later designs employ processors with flash memory.
