All wiring of the standard Magnum flowmeter is done through the 10 pin connector on the right hand side of the transmitter. By removing the cover from the detacheable portion of the connector the user has access to heavy duty screw-type terminals to connect power input, signal output and a variety of external equipment.

The MAGIO 3.0 software at one point uses a wiring diagram as seen below on the left. This is intended for the new Magnum IC model flowmeter which is not yet in production. Instead use the wiring diagram on the right, intended for the standard Magnum which also corresponds to the connector seen above.

The sensor cable is lead to the transmitter through an 8 pin round connector on the left side of the transmitter casing. Also on the left side is the 5 pin round connector for the serial port/PC interface cable.
