Connecting Sensor Cables to Optima+ 4 BT

The Optima+ 4 BT devices comes with a the Optima+ 4 Bluetooth amplifier, 7 snap-in sensor cables and a Velcro strap.
The sensor cables are wrapped in 3 separate bundles. 

Channel 1 contains 3 cables: red for active, black for reference and green for the Ground sensor.
Channel 2 contains 2 cables: white for Channel 2 active, Brown for reference and a jumper cable for linking the black and brown reference cables together.
Channel 3 and Channel 4 contains 2 cables: Yellow and Blue for Channel 3 and Channel 4 actives. The Reference will be shared from the Brown cable with the Channel 2 bundle.
The Optima+ 4 BT device ports are labeled +A- (red and black), +B- (red and black), VG (white port) and SH (blue port).  The red "A+" port is the Active port for Channel 1 and the black "A-" port is the reference port for Channel 1.

The red "B+" port is the Active port for Channel 2 and the black "B-" port is the reference port for Channel 2.  The white "VG" port is the shared Ground connection for Channel 1 and Channel 2 and the blue "SH" port is unused by SmartMind.  A labeled diagram is found below showing the port names and locations.
For a 1 Channel placement, you will only need the Channel 1 batch of cables (red, black and green). 

  • The Red sensor connects to the red "A+" port for the Channel 1 active sensor.

  • The black sensor plugs into to the black "A-" port for the reference sensor. 

  • The green cable connects to the white "VG" port to function as the ground.  
For a 2 Channel Placement, you will need all 5 cables and the jumper.

  • The Red sensor connects to the red "A+" port.

  • The White sensor connects to the red "B+" port for Channel 2.
  •  
  • The green cable still connects to the white "VG" port to function as the ground.
  •  
  • You will use the jumper to connect the black "A-" port and the black "B-" port together.

  • Then plug the black cable into the jumper located at "A-" port and the brown cable into the jumper located at the "B-" port.
For a 4 Channel Placement, you will need all 7 cables and the jumper.

  • The Red sensor connects to the red "A+" port.

  • The White sensor connects to the red "B+" port for Channel 2.
  •  
  • The green cable still connects to the white "VG" port to function as the ground.
  •  
  • Use the jumper to connect the black "A-" port and the black "C-" port together.
  •  
  • Then plug the black cable into the jumper located at "A-" port and the brown cable into the jumper located at the "C-" port.

  • The Blue and Yellow cables would then connect to the red "C+" and "D+" ports for Channel 3 and Channel 4.

  • If you are only using 3 channels, then simply do not connect a sensor cable to the red "D+" port, but the other connections would remain the same.
Once you have the sensor cables connected to the Optima device, use the supplied arm band to position the device on the upper arm of the trainee/client. This combined with the shorter sensor cables will help to minimize cable movement which can lead to excess noise and 'pops' in the signal during training.
