Mounting the Computer

Picking an ideal position for the computer screen

  • A bar or bracket across the window or side panel of the passenger side of the tractor when seated in the cab is ideal.
  • Use provided ram mounts to connect to the bar or bracket. Drill holes and use bolts if necessary.
  • Make sure there is easy access to the touch screen at all times and that the operator can see the computer at all times.
  • Make sure it is secure as it will take a lot of vibration and bumps during operation.
  • See Picture for a generic placement of the computer screen.

Power Connections

Power:

  • Most tractors have convenience ports; this is the easiest place to connect the control computer, DAC 7000, and GPS power.
  • Convenience ports: Pictures 12.1-12.3
  • John Deere has convenience ports on the right hand side of the tractor on the dash by the back right post. Picture 12.1.
  • CNH has convenience ports on either the front right corner post or behind the seat on the right side (both work well, just depends on how you want the cords to run). Pictures 12.2a and 12.2b.
  • CAT Challenger - Tracked
    -
    Challenger A/B has convenience ports behind the seat on the right side. Picture 12.3.
    - Challenger C/D/E may need an adapter cable from the power strip to a convenience port.
  • If your tractor does not have a convenience port, you should find both constant power and switched and bring that into the cab, and wire in an in-line fuse (10 amp).

 

Cables:

Routing overview:  Run the GPS cables and the electric over hydraulic control cables out of the cab.

  • John Deere – out the back window through the rubber seals
  • CNH - out the bottom of the cab; under the right side through the rubber or foam; or out the back window.
  • CAT – out the back window through the rubber seals
  • Make sure all cords are tied up and excess is not in a position to get caught on anything or kicked by the operator’s feet.

Control computer:

  • COM 1 (serial) is for GPS ALWAYS (green)
  • COM 2 or COM3 (serial) are for the electronic over hydraulic controller (DAC 7000). Typically COM 2 on Sailor and COM 3 on AFL2-12A (brown, see starting page 18).
  • See Section 1 - Wiring Diagrams for complete cable hookups.

 

Mounting the GPS Antenna

  • The GPS antenna needs to be mounted directly above the scraper blade or plow tip.
  • It should move 1:1 with the blade or tip.
  • It should be mounted high enough to acquire signal above the tractor (3-6 foot mast is recommended). Scraper: Picture 17.1. Tile Plow: Picture 17.2.
  • Make sure the GPS cord running back to the tractor from the antenna is attached securely and not hanging loose.
  • Check that there is enough slack in the line for the movement of the implement and turning of the tractor.

Slope Definitions

Hydraulic Control John Deere

  • John Deere-00-R Series:
    For the electronic over hydraulic control cable (DAC-7000-JD), the gray connector off the DAC 7000 will run outside through the back window. Remove the back panel that the ‘slow moving vehicle’ sign is attached to. The connection will be made underneath that panel on the left side when looking toward the front of the tractor. Make sure the tractor isn't running when plugging the cord in or it will throw a code in the tractor.  When it is plugged in and the key is on, the tractor should show ‘EC’ (or ‘Auto’ on R Series) on the hydraulic screen showing that the cord has been plugged in. See Pictures 13.1, and 13.2 for examples.

Hydraulic Control CASE and New Holland

  • CNH – for the electronic over hydraulic control cord (DAC-7000-CIH/NH), the gray connector will come off the DAC 7000 and run outside either down underneath the cab on the right side or out the back window.
  • On the MX Series, the connection is under the ‘slow moving vehicle’ sign.
  • On 2010 and older QuadTracs, the connection is hanging below the cab on the right side (when looking from the back of the cab). See Picture 14.1 (just to the right of the arrow).
  • On the 2011 QuadTrac and newer, the connector is inside the cab under the plastic on the right hand side. See Pictures 14.2a and 14.2b

A “1-3 switch” (must be installed by a CNH dealer, contact your local dealer) is also needed to give SD Drain control of the machine (see Pictures 14.3a and 14.3b).

The tractor will now need to be programed to “Scraper 1” on the corner post.

  • For 2011 and older: with the key Off, hold the Program (PROG) button on the corner post, turn the key one notch to the right, then use the arrows to go down to AUX.  Hit PROG button, then arrow down to AUX Setup, hit the PROG button, arrow down to Scraper 1 (unless you have a slope sensor, then use Scraper 2).  Hit PROG button, then arrow down to AUX Exit, then hit PROG button. Arrow down to EXIT, then hit PROG button. Turn key to OFF.
  • For 2012 and newer: Turn the key switch to the On position and within 10 seconds press and hold the Enter key on the keypad to enter the Config Menu screen. Use the Up or Down arrow keys to highlight “TCU” and press the Enter key.  Use the Up or Down Arrow key until “EHR Menu” is shown and then press the Enter key.  Use the Up or Down arrow key until “EHR SETUP” is shown and then press the Enter Key.  SCRPR NONE will be shown on the screen.  Use the Up or Down arrow key until “SCRPR-1 LASER” (unless you have a slope sensor, then use “SCRPR-2 LASER”) and then press the Enter key.  Turn the key to the Off.

 

Hydraulic Control CAT "A"and B Series

  • Challenger A/B will need to be run outside through the back window and down to the hydraulic block. It is best to use Hydraulic #1, but 1-4 can be used. Numbers 5 and above do not work. Disconnect the connections and reconnect the new ones (note or label which ones they are so they don’t get mixed up). Pictures 15.1-15.2.

Hydraulic Control CAT C Series and newer

  • Challenger C/D: DAC 7000 controls plug in behind the fuse panel inside the cab, by the floor. Hydraulics #1 and #2 will be able to be controlled.  Hydraulic #1 if only one is used.  The CAN connector will connect to the CAN bus extension cable on the right side of the fuse panel.  The connection will be a black 4-pin connector.  After the tractor is started, the enablement of the isobus control may be needed (Picture 15.3 and 15.4).
  • To enable controls, select the wrench button on the main tractor screen (Picture 15.5). Select the second page button (bottom right) (Picture 15.6).  Make sure Isobus Class 3 is enabled (Picture 15.7). The end result should be Picture 15.8.

External Valve

  • External Valve controls (Picture 16.1) will need to be run from the DAC 7000 to the outside of the cab and run to where the external valve is mounted. This cable needs to be tied up well so that the cable doesn’t hang.
  • Multi-Function Joystick - Run the joystick (Picture 16.2) from the DAC 7000 making sure the cables don’t get caught or pinched under the seat.
