3. A Tour of neoECU-12 Hardware

3.1. Case and Overall Design

The neoECU-12 is enclosed in a lightweight plastic case. The device has been designed and tested for in- vehicle use, and is operational in a temperature range from -40°C to +85°C.

The pinout for the DB25 male connector is on the bottom of the case.

3.2. Front side of Case

The front side of the case contains the DB25 male connector.

3.3. Back side of Case

The back side of the case contains the serial number and tri-color LEDs.

3.4. Controlling the Tri-Color LEDs

The neoECU-12 has default behavior for the first two tri-color LEDs. The 1st LED is for HS CAN 1, the 2nd LED is for HS CAN 2 and the 4th LED is for LIN.

Interpretation of RGB LED Colors

These are “RGB” LEDs because they contain separate red, green and blue elements. For networks, each indicates a different aspect of the device’s overall status:

Green: Device is transmitting messages on this channel.
Blue: Device is receiving messages on this channel.
Red: Device is detecting errors on this channel.

It is possible for more than one LED component to be lit, producing the following results:

Green+Blue (Cyan): Device is transmitting and receiving on this channel.
Green+Red (Yellow): Device is transmitting and detecting errors on this channel.
Blue+Red (Magenta): Device is receiving and detecting errors on this channel.
Green+Blue+Red (White): Device is transmitting, receiving and detecting errors on this channel.

LED3 blinks magenta when a function block script is running.

In bootloader mode, all five LEDs blink red in succession.

3.5. Optional neoECU 12 Programming Board

Programming Board for the neoECU-12. You can use with a ValueCAN 4 Series device to flash scripts into the neoECU-12.

Note

12 VDC power is required to power the NEOECU-12-PB. Use the NEOVI-PS Power Supply (not included) or your own 12 VDC power supply via the barrel connector on the board.
