Error 208 is a communication timeout alert. It indicates that a hardware module started an operation but has stopped "talking" to the master controller while that operation is still active.
You will receive Error 208 when the machine detects that a specific module (like a valve bank or inductor controller) has stopped sending operational updates back to the master controller.
Essentially, the master controller sent a command, but the module has gone "silent" before finishing the job. This error is almost always accompanied by a 3-Blink Error Code on the hardware's physical status lights.
This error is most commonly triggered by a weak power source. If the voltage drops too low when a motor or valve draws power, the module may lose enough energy to stop communicating.
Monitor Mixmate Voltage: Check the voltage on your tablet screen. If it dips significantly when you start a pump or valve, your battery or charging system is the likely culprit.
Reboot the Mixmate. Power the entire system down and back on. This resets the communication state for all modules and often clears temporary "glitches" in the message timing.
Physically check all CAN bus cables. Look for loose connections, moisture in the plugs, or wires that have been rubbed raw. A intermittent connection will cause the "silence" that triggers Error 208.
Like other communication errors, 208 can be caused by improper electrical termination.
To test the resistance:
SHUT OFF ALL POWER to the Mixmate.
Locate the Power Module (the white box).
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.
