    TR-HT2xx LED Controller - User Manual Mounting the TR-HT Mount the TR-HT on a flat surface using M4 screws through the mounting holes in the unit's case. The illustration below shows the positions of the mounting holes. Environmental considerations The TR-HT enclosure is a fire enclosure as long as it is mounted so that none of the connectors are facing downwards.

  • Page 17: Electrostatic Discharge

    TR-HT2xx LED Controller - User Manual Mount the TR-HT such that there is a free flow of air around it. Under certain conditions, the TR-HT requires additional heatsinking in order to prevent overheating, as follows: Both channels operating: If the ambient temperature rises to 30°C or above, the TR-HT must be bolted to a metal structure that absorbs sufficient heat to keep the internal temperature reported by the TR-HT to 65°C.

  • Page 30: Digital Inputs And Outputs

    TR-HT2xx LED Controller - User Manual Digital inputs and outputs The TR-HT controller has four digital inputs (through the trigger input connections), four digital outputs, and eight virtual outputs (see Section 8.4, Virtual outputs). All outputs operate independently and are configured separately.

  • Page 31: Output Modes

    TR-HT2xx LED Controller - User Manual Output Modes Each output operates independently. By combining which outputs are triggered by which inputs, and which mode each output is in, it is possible to configure complex sequences of operation. Multiple outputs can be triggered by one input to give synchronous operation, or from separate inputs to give asynchronous operation of different functions.
  • Page 32 TR-HT2xx LED Controller - User Manual Mode Mode Operation name Set Low The output is set to off or logic 0. If the output is inverted (flag O is set) then the output is (Off) logic 1. Set High The output is set high (on) or logic 1. If the (On) output is inverted (flag O is set) then the output is logic 0.
