Introduction

To test the OpenMotics modules after being released from production, a test system has been created. The goal of this Test System is to verify the different components of each PCB.

The Test System needs following components:

  • Test System PCB
  • CAN Control PCB (without Front panel)
  • 2 Power supplies 24VDC

Release Notes of the Test system firmware can be found here: Test System Release Notes

Number of errors during testing

When the module if fully tested, the above information is written in to the Eeprom of the salve module.

The serial number can be manually written or changed by doing following steps:

  • Use the Pickit programmer to be connected to the module
  • Switch off read/write of program memory, switch on read/write of Eeprom memory
  • press read
  • Change the bytes in the above locations. Please note that the location is in hex format, the value written is in hex format as well.
  • press write
  • When the debug connector is connected to the programmer, you can check if the serial number is well written by switching on the module (by using the programmer for example), the console will display the programmed serial number.

Connecting the Test System

Following connections needs to be made:

  • Connect an UTP cable between the Test System and the CAN Control
  • Connect the 2 power supplies on Connector J1 (see above drawing)
  • Connect the Test PC RS232 connection to C1 of the Can Control (Baudrate 38400)
  • A Start Button (to start executing a test) can be connected (J4_15 & J4_25)
  • A stop Button (to interrupt an ongoing test) can be connected (J4_16 & J4_26)
  • Connect Can Control C5 to Test System:
From To Description
C5_1
J9_25
GND: Connect the Ground between the Can Control and the Test System
C5_4
SV3_4
SCL: Connect I2C lines between both boards
C5_5
SV3_5
SDA: Connect I2C lines between both boards
C5_8
J9_23
5V: Connect 5V between both boards

CLI interface

Connecting

On the RS232 connection of the CAN Control, an USB-RS232 convertor can be used to access the CLI interface (speed 115200). When enter (CR/LF) is pressed, the module will respond with

OK

Serial Number

The serial number of the OpenMotics modules consist of 12 digits:

  • The first 6 digits is the date start with the year, for example 14th June 2021: 210614
  • The next digit is the production company that performed the testing:
    • 0: OpenMotics
    • 1: Page
    • ...
  • The last 5 digits is the serial number (0-65535) in other words, for a given day, maximum 65535 devices can be produced. Example: 00289
  • An example of a full serial number: 210614100289

Notes:

  • This instruction is for the moment only used to set the hardware version of the uCAN. The newer uCAN's have another hardware layout (between revision "E" and "F") making sensors not working correctly so it's important, when programming uCAN's, to set the right hardware version.
  • The old uCAN hardware revision "E" that have been tested in the past have been programmed with firmware version 255
  • The new uCAN hardware revision "F" must be programmed with value 70 (= ascii F) so make sure this setting is used
  • When newer uCAN hardware is released, for example revision "G", value 71 (= ascii G) should be used

Read/write serial number in module without a full test

During a normal test, the serial number is always written at the end of a full test. In certain circumstances, we want to read/write the serial number only.

  • read serial number only of the selected slave module:
sr
  • write serial number only of the selected slave module:
sw
