Channel Naming Convention
All channels follow the pattern:
{ModuleSlotIndex}.{ProductID}.{ChannelName}
Examples:
0.ESH10000590.ADC_CH0 ← slot 0, Precision ADC/DAC, first ADC input
1.ESH10000025.GPIO_OUT_00 ← slot 1, GPIO module, first output
0.ESH10000121.I2C_BUS_0 ← slot 0, MPIO-I2C, first I2C master
ModuleSlotIndex is the physical slot position in the Accordion backplane (0-based).
