Interfaces

Digital Inputs

EVIC is equipped with 8 digital inputs that can determine input states from switches or buttons. Digital inputs 1 through 7 are triggered by sourcing +12V. Digital input 8 is triggered by sinking to GND.

DIN 1 - 7                                                    DIN 8

            

 If you have not correctly mapped the digital inputs to skin graphic labels or images, then nothing will occur when switching these pins.

Digital Outputs

EVIC is equipped with 8 digital outputs that are low-side switches. They are designed for a variety of applications including LEDs, external relays or buzzers.

Analog Inputs

EVIC is equipped with 5 analog inputs (1 on the main connector, 4 on the analog input connector) at 12-bit resolution. They can be used to read measurements from many sensors such as temperature, potentiometer or brake transducers. There are reference 5V and ground outputs provided on the analog input connector to supply power to sensors if necessary.

AIN 1 - 5

   

CAN Channel

EVIC can operate as a single node or as a multi-node on the CAN bus network.

EVIC can be configured as either terminated or non-terminated on the network. EVIC is shipped terminated. You can un-terminate by taking apart EVIC's back cover and removing an internal jumper (P2) on the board.

Baud Rate

EVIC is configured by default at 250 kbps baud rate. EVIC's configurable baud rates are 125, 250, 500 or 1000 kbps.

Note: If data does not appear or is displayed intermittently, please verify CAN baud rates are set correctly for all components on the network.
