Also included is an adapter from screw terminals to a 5.5x2.1mm barrel jack, center positive. If you
disconnect and reconnect the adapter, make sure the + screw terminal is connected to red and the
- screw terminal is connected to black. An appropriate 24 VDC power adapter is included.
Any 6VDC to 30VDC power adapter at 2A with a 5.5x2.1mm barrel connector, center positive can be
used instead, if desired. For automotive use, you can use this power input directly to a 12V or 24V
vehicle power system as the power supply is designed to handle transient voltage present on
vehicle power systems.
The RS485 and CAN interface pins on the M12 8-pin connector cannot be used as GPIO.
The Monitor One includes a M12 4-pin male to flying leads cable, 1500±20mm (about 60 inches or 5
feet).
