Attention:

• To set up a USB via the Molex connector, please specify this requirement when ordering, or the device must be sent back to Influx (as this requires some hardware modification).

Note:

• Pins not mentioned in the description table(s) are NC.

Notes:

• The connector must be tightened securely to connect properly, ensuring reliable operation.

• Each end of the CAN bus must be terminated with a 120 Ohm resistor across CAN H & CAN L.

• Do not short-circuit any pins.

• The maximum safe applied voltage for analog and digital I/P is ±28 V

• Do not use the logger's USB port for data logging, as it may damage the USB port, which won't be covered under warranty.
