Note: Due to changes in the production process there are 2 versions of the micro CAN with regards to the wiring bundle.

  • The first (obsolete) iteration has flexible (multi-strand) cables and uses dashes in its color scheme: refer to column "Color" in the table below.
  • The second (current) iteration has solid copper core cables and uses a black shrink wrap on certain cables: refer to micro CAN Connections page

Connection Color Description
1
White Output Common (If the leds are powered for example by 12VDC, the + of the 12VDC is connected to this connection and to the common anode of all leds connected on this module) - Max 24VDC - The Leds CANNOT be powered by Connection 10 (5V OUT) !!
2
Brown Output Led 6 (The cathode of led 6 will be connected to this connection)
3
Green Output Led 5 (The cathode of led 5 will be connected to this connection)
4
Yellow Output Led 4 (The cathode of led 4 will be connected to this connection)
5
Grey Output Led 3 (The cathode of led 3 will be connected to this connection)
6
Rose Output Led 2 (The cathode of led 2 will be connected to this connection)
7
Blue Output Led 1 (The cathode of led 1 will be connected to this connection)
8
Red GND (Common for all switches and GND for sensors)
9
Black GND (Common for all switches and GND for sensors)
10
Purple 5V OUT (To power the external sensors, NOT to power the leds !!)
11
Rose-Grey Input 6 (To connect switch 6)
12
Blue-Red Input 5 (To connect switch 5)
13
White-Green Input 4 (To connect switch 4)
14
Green-Brown Input 3 (To connect switch 3)
15
White-Yellow Input 2 (To connect switch 2)
16
Brown-Yellow Input 1 (To connect switch 1)
17
White-Grey Sensor Output 2 / Sensor SCL (i2c)
18
Brown-Grey Sensor Output 1 / Sensor SDA (i2c)
12-24V IN +
Green Connector DC power (+) coming from the bus cable
12-24V IN -
Green Connector DC power (- or GND) coming from the bus cable
CAN H
Green Connector CAN connection (H) coming from the bus cable
CAN L
Green Connector CAN connection (L) coming from the bus cable
Note 1: TR is used to place the Termination jumper. The termination jumper is placed at both ends of the Bus. 
Typically, the Bus starts at the CAN Control (so the termination jumper will be placed at the CAN control) 
and ends at a CAN Micro so this last CAN Micro will have a termination jumper as well.
Note 2: The CAN Micro module has also a tri-color led on the back of the module. 
The indication of the leds can be found on CAN Micro led functions.
Note 3: Below, you find 2 examples how to connect the CAN Micro, one example with 2 temperature sensors, 
one example with the Honeywell temperature/humidity sensor
Note 4: The Honeywell sensor exist in 2 versions: The standard HIH8121-021-001 (around 12 Euro/piece) and
the HIH8121-021-001S (Around 61 Euro/5 pieces). 
Note 5: The Honeywell sensor only measures positive temperatures (for all micro CAN modules delivered until end of december 2017) so for an outside sensor, please use a DS1820 or similar sensor
