RH95 will not connect to T9X controller

If your software or Linkpad is not showing the option to control the humidity, despite the RH95 being connected to the system, please check the following:

  • Check that the RH95 has been powered on before the T9X controller.
  • Check that the serial cable that connects from the T95 controller to the RH95 is the correct way round. The end labelled 'Ext 232' should be connected to the T95 controller, and the end labelled 'Hum 232' should be connected to the back panel of the RH95. Note that due to a change in the T96 design compared to the T95, this does not apply to systems with a T96 controller.
