Tablet Error 105 - Critical Device Missing

Error 105 occurs when the master controller cannot communicate with a specific component (like a flowmeter, valve, or inductor) required for the system to function.


Why am I getting this error?

You will receive Error 105 when the machine detects that a device required on the CAN bus (the communication network between your Mixmate parts) is missing or not responding. If the master controller cannot "see" a device it needs for the current operation, it will halt the process to prevent an inaccurate mix.


How do I resolve this error?

1. Basic Reset

Start by rebooting the Mixmate hardware. Power the system down completely and turn it back on to force the master controller to re-scan the CAN bus for all connected devices.

2. Physical Inspection

Check the wiring across your entire system. Ensure that all cables are securely plugged in and that every device is receiving power. A loose plug or a cut wire is the most common cause of a "missing" device.

3. Check CAN Bus Resistance

Like other communication errors, 208 can be caused by improper electrical termination.

To test the resistance:

  1. SHUT OFF ALL POWER to the Mixmate.

  2. Locate the Power Module (the white box).

  3. Using a digital multi-meter, measure the resistance between the GREEN and YELLOW wires.

Resistance Standards:

  • ~60 Ohms: Ideal. (Two healthy terminators detected).

  • ~120 Ohms: Faulty. (Only one terminator is working).

  • 70–135 Ohms: Intermittent issues and 208 errors are very likely in this range.

  • <50 or >135 Ohms: The system will not function.
