sensors varies with speed of rotation, variable trigger levels are required,
which must vary with the frequency of the input signal.
The Speed Inputs can also be used with Hall Effect type wheel speed
sensors.
The Pulse Width measurement method measures the high time of the
pulse rather than the low time as measured by the Digital Inputs.
Input Specifications
For full specifications refer to Input Characteristics.
Expanders
If additional sensors are required, input expanders can be used e.g. E888,
E816, VIM, SVIM. Sensors can be connected to the expander inputs and
communicate via either RS232 or CAN. See Configuring Communications.
Outputs
Auxiliary Outputs are used to control various vehicle functions e.g.
o Gear Change Lights
o Warning Lights
o Thermatic Fan
o Gear Box Oil Pump
Note: Devices that consume more than the maximum current (e.g. motors)
should be driven via a relay or PDM.
Output Specifications
Full specifications can be found in Output Characteristics.
Expanders
If additional outputs are required, output expanders can be used e.g.E888,
PDM. Expander outputs can perform the same tasks as the device outputs
and can be driven by communication via either RS232 or CAN. See
Configuring Communications.
Communications
Communications are used to send and receive data from one device to
another. There are two communication protocols; RS232 and CAN. Generally
older devices use RS232 and newer devices use CAN.
