    It is imperative that the rise time of the signal is greater that 1uS. Failure to adhere to this specification may cause output inaccuracy. The minimum low period of the zero cross signal is 10uS. The allowed frequency range is 90Hz to 125Hz. Frequencies outside this range will cause non linear output.

  • Page 100 System The AL2001 and AL3001 communicate via a bi-directional eleven bit Operation parallel bus. The AL2001 contains all phase control timing circuits including the phase locked loops used to synchronise to mains frequency. The AL2001 is also responsible for reading the analogue control voltage inputs and the temperature sensor.
  • Page 101 DMX512 The DMX512 input connects directly to the output of a standard Input RS485 or RS422 receiver such as the 75176. The base address of the received block of twelve channels is set via the keypad and stored in eeprom. The DMX512 data is merged with the analogue inputs on a highest takes precedence basis.
