SSD Interface Manual (continued)

GM / SM GET / SET MODE COMMAND

Used to change the sensor options.

Bit0 Invert Current – This will flip the Current and Coulomb signs if necessary.

Bit1 Autorange – Sensor will switch to high range if reading exceeds 85 % of standard range. It will switch back when reading drops to

below 50 % of standard range. See A2D CONFIG for more info.

Bit2 Modbus Enable – Enables Modbus on reboot.

Bit3 Auto Reset Errors – Self clears errors once sent or read, the error will re-enable if it persists.

Bit4 Invert Voltage – Use for Highside Voltage Measurements.

Bit7 Send on Conversion – The sensor will send the latest data as soon as available per A2D CONFIG.

Bit8 Autosend – The sensor will send readings at the Read Delay timer interval unless Bit7 is enabled.

Bit9 to Bit15 – Enable the readings to be automatically sent. Otherwise read them manually.

Value is an unsigned Int16. SET MODE default is: 0x0002.

Example: Set SSD to Autorange, Autosend Current and Temperature at the read delay interval, and Autoreset Errors. (0x070A)
