Description

MCE18 stands for “Multifunction Can Bus Extension” with 18 connections – why is this module needed?

More inputs!!

ECUs and Displays only have so many inputs and in some applications you will need more than you have in your devices.
MCE18 can accept 9 analog inputs and 9 digital inputs and broadcasts the voltages of these inputs back on the CANbus for your other devices to receive.  – eg CANchecked display, Dash, PDM or ECU.

Tested with:
– MaxxECU
– Ecumaster (EMUB and PMU)
– LinkECU
– Haltech (emulates an IO Expander A + B or just B)
– Emtron

This device is also available without a housing:  CFE18 – can switch board


– Hardware –

The MCE18 kit includes:

  • MCE18 with housing
  • Connector Superseal 34pin (TE 4-1437290-0)
  • Pins Superseal 1.0 20AWG (TE 3-1447221-4)
  • 3 jumpers

There are versions of the MCE18 where the connector is rotated and the locking tab is on the bottom. Please note that the 12V pin is always on the top left of the device.

– Jumper configuration –

MCE18 inside jumper

If you remove the front 4 screws, you can pull off the housing. There are three jumpers on the back.

1) JP1 plugged in activates the 120 Ohm resistor for the Can Bus
2) JP2 plugged in activates the 1K1 pull-up resistor for A1 and A2
3) JP3 plugged in activates the 1K1 pull-up resistor for A6 and A7

By default, all jumpers are removed


Configuration Details

– Default Can Bus Stream –

**Specify your ECU at checkout and we’ll configure your device before shipping**

The data of the inputs are queried and transmitted every 50ms (20Hz – changeable). The data is transmitted as “unsigned big endian”.

As soon as 12V and ground are connected, the green status LED on the back lights up.
Can Bus ID: 0x700 ( Base Data CAN ID – changeable)

byte 0 1 2 3rd 4th 5 6th 7th
Base ID AIN0 0-1023 AIN1 0-1023 AIN2 0-1023 AIN3 0-1023
Base ID +1 AIN4 0-1023 AIN5 0-1023 AIN6 0-1023 AIN7 0-1023
Base ID +2 AIN8 0-1023 bit masked DIN0-7 DIN0 0-1 DIN1 0-1 DIN2 0-1 DIN3 0-1 DIN4 0-1
Base ID +3 DIN5 0-1 DIN6 0-1 DIN7 0-1 DIN8 0-1 unused

The configuration or modification of the Can Stream is described in the CFE18 – Can Bus Function Extension .


– AIN smoothing –

* From software version 3

If the analog inputs fluctuate too much, they can be smoothed using software. This can be configured separately for each analog input.

The analog inputs are evaluated with each transmission (default: 20Hz).

setting smoothing
0 no smoothing
1 2
2 4
3 8
4 16
5 32
6 64

If, for example, a smoothing factor of 4 is set, the average of the last 16 measurements is taken. This makes the value quieter (smoother), but also reacts more slowly to fluctuations. Here you have to find a healthy middle ground to suit your application and sensors.

The setting is made via Can Bus – see CFE18 => ” Configuration options ”


– Control unit / ECU configuration –


**Specify your ECU at checkout and we’ll configure your device before shipping**

The analog inputs provide 10-bit resolution and thus values ​​from 0 to 1023. The value must be converted in the control unit. All values ​​are “unsigned big endian”

Examples:
5V voltage AIN0
0x700 Byte0 + 1
multiplier: 5; Divisor: 1023; Offset: 0

or multiplier: 0.004887585533

Flue gas temperature (type k) AIN7:
0x702 Byte6 + 7
Multiplier: 1250; Divisor: 1023; Offset: 0

or multiplier: 1.2218963832


Either the individual bytes are used for the digital inputs. Eg DIN6: 0x702 byte 6 or the bit mask at 0x702 byte2

eg DIN6: 0x702 Byte2 Mask: 0x40
