Page 20: Analogue And Digital Outputs (Ad1 & Ad2)
The pulse per meter range is adjustable in software. The digital output on connector AD1 is a simple on/off state output. This digital output can be associated with any of the data channels being logged by the VBOX. A threshold level can be set for the selected data channel where a true condition gives a 5v output and a false condition gives a 0v. -
Page 21: Digital Inputs (D In)
Digital Inputs (D IN) The „D IN‟ connector contains the two digital inputs for a VBOX 3iSL. Digital input 1 is also referred to as the Brake trigger input. This input is connected to an event capture input on the GPS engine. This captures precisely the trigger event time (10nS resolution) for use in brake distance calculation. This period of time is called the trigger event time, and is logged and used to correct the measured brake stop distance to the exact point at which the trigger was pressed. -
Page 22: Analogue Inputs (A In)
Analogue inputs (A In) a VBOX 3iSL contains four differential 24bit analogue input channels with a maximum sample rate of 100Hz. Each channel has its own dedicated analogue to digital (A/D) converter with all four channels being sampled synchronously to each other. The voltage range of the input channels is ±50volts. Note that unlike the ADC03 module, the analogue channels in a VBOX 3iSL are not electrically isolated from each other. -
