Cabling

This section describes all of the many cables that need to be connected properly before the AO system will work properly.

The motor control rack is the rack mounted on the west side of the AO optics bench. The computer rack is the rack mounted on the east side of the AO optics bench. The "front side" refers to the side of the AO bench with most of the optics (DM, WFS, etc.). The "back side" refers to the side of the AO bench with most of the electronics and cables.


Power

There are many power cables in this system and it is imperative to get the power distributed properly, otherwise circuit breakers will be tripped and UPSs overloaded.
  1. The tray underneath the AO optical bench has 6 power cables. 4 plug into the motor control rack, 2 plug into the computer rack. The cables and outlets are labeled with colored tape to indicate which plugs go to which outlet.

    There are 2 UPS units available for AO power.

    Power Distribution Summary
    UPS OutletPower CableEquipment
    TUB UPSGreen, YellowPulizzi 1 (24V power, filter wheels, RLS), Pulizzi 2 (motor controllers)
    AO UPS (above TUB)Blue, Orange, Brown, WhitePulizzi 4 (IRCAL motor controller); Pulizzi (AOA camera); lgs7, lgs11, ethernet hub, Pulizzi (100V lambda power supply, left monitor); lgs14, ethernet hub, Pulizzi 3 (SWFS camera)

  2. TUB UPS: The green and yellow labeled power cables get plugged into the TUB UPS plug strip. You may have to unplug some of the unused KAST electronics to get enough free outlets to plug in AO.

    The yellow labeled power cable powers Pulizzi 2 (motor controllers).
    The green labeled power cable powers Pulizzi 1 (24V power, filter wheels, RLS)

  3. AO UPS: You will have to string a long extension cable from the AO UPS to the AO bench back side. Please strain relieve and cable-tie the extension cord in place so it does not accidentally come unplugged. The outlet box gets velcroed to the AO tray. The blue, orange, and brown labeled power cables get plugged into this outlet box.

    The blue labeled power cable powers Pulizzi 4 (IRCAL motor controller).
    The orange labeled power cable powers a Pulizzi (AOA camera).
    The white labeled power cable powers lgs7, lgs11, ethernet hub, and Pulizzi (100V lambda power supply, left monitor).
    The brown labeled power cable powers lgs14, ethernet hub, and Pulizzi 3 (WLS, back WFS camera).

  4. Turn on the power to the pulizzi power controllers (these are the remotely operated 8 channel power controllers, there are 4 in the motor control rack, 2 in the computer rack).

  5. Make sure power is on for the power strip in the top section of the computer control rack (is shouldn't ever be turned off, but sometimes it does).

  6. Plug the Slow WFS camera power cable into the labeled outlet on the motor controller rack back side.


Ethernet

  1. Ethernet cable from TUB to computer rack ethernet hub port 8. The ethernet hub is at the top of the computer rack, back side.
  2. There is an ethernet cable strung across the top of the back side of the AO bench. One end gets plugged into port 8 on the motor control rack ethernet hub. The other end gets plugged into any port other than 8 on the computer rack ethernet hub (at the top of the back side).

Read Out Room

There are a few cables in the Read Out Room that need to be connected:
  1. Tip/Tilt offload cables: These 3 coax cables are connected from the TUB patch panel to the patch panel just above telco. The cables are:
    TUB Patch PanelTelco ConnectionFunction
    72 Y-axisY Offload
    81 X-axisX Offload
    93 EnableOffload Enable
    (Note: make sure that the connections from the telco panel to telco are also in place.)
  2. AOA camera video: This coax cable connects from TUB patch panel 16 to the Video A In channel of the AO system Sony monitor.
  3. (optional) Telex communication system consists of two base stations that can be plugged in anywhere. There is a grey cable (labeled Telex at both ends) that connects to the I/C 2 port on the back of each unit.

Grey Rack

The grey rack sits on the dome floor. Most (but not all) of the equipment in this rack is no longer used.
  1. Power: The grey rack has two power cables that plug into an extension cord (typically a large yellow one with a 4 outlet box) that is plugged into the AO UPS outlet on the telescope control console. Turn on the power to the two pulizzi power controllers.
  2. Ethernet cable from the ROR (currently a green cable labeled laser guide star) connects to lgs8 (the lantronix on the back of the grey rack).

Umbilical

As of June 2004, the only items in the Umbilical bundle that are used are the water lines and the Slow WFS Camera Cable. The umbilical cable strain relief mounts to a bolt through the AO frame near the motor control rack back side.

  1. The two Water Lines connect to the patch panel on the AO bench. The two connectors often leak a little water when being connected, but once connected should not leak at all.
  2. Slow WFS Camera Cable. This SCSI cable is on a spool next to the telescope control console. It needs to be connected to the Slow WFS Camera mounted in the middle of the south side of the optical bench. This cable gets strain relieved and cable tied to the water line umbilical.

Motor Control Rack, front side

There are a number of red motor control cables with MS connectors that need to be threaded around the AO bench frame from the back side to the front side.
  1. Motor control cables are all labeled and need to be connected to the correspondingly labeled port on the patch panel.

  2. There are 6 cables DB25 connectors for the Renishaw encoders, labeled Amp 1 to Amp 6, that need to be threaded from the AO bench back side to the front side patch panel. Connect them to the appropriately labeled connectors on the patch panel at the bottorm of the motor control rack.
  3. Red Light Source Power: The HeNe laser that is used for the red light calibration source needs to be installed in the AO bench tray (using the velcro which is already there) and plugged into the power outlet labeled Red Light Source. The HeNe laser is typically stored on the desk in the AO prep room and should be handled with care (particularly the fiber exiting the microscope objective mount) during installation. The microscope objective end of the laser assembly is installed closest to the motor control rack. Make sure that the laser is firmly attached to the tray by the velcro and pointing towards the right. The laser power supply is installed with the (taped over) LED facing the motor control rack on its own velcro. All cables should be neatly tied down using the available velcro.

Motor Control Rack, back side

There are a large number of different cables that need to be connected here and it is easy to miss one (though with this checklist that shouldn't happen, right?).
  1. Slow Wavefront sensor (SWFS) power. The SWFS camera power supply is mounted near the center of AO bench back side. It is a regular 120V power cable that plugs into the labeled outlet at the bottom of the motor control rack back side.
  2. White light source fiber is a metal clad cable strung across the top of the AO bench. This cable gets screwed into the back of the Oriel Radiometric light source.
  3. High Voltage Coax Cables

  4. APD 5V/12V power is a PC power supply velcroed in place at the bottom center of the back side of the AO optical bench.
  5. RJ45 Motor controller cable plugs into the small plastic RJ45-RJ45 junction box.
  6. Water lines (from Umbilical) to the bottom patch panel.
  7. IRCAL Cables: See IRCAL section.

Computer Rack, front side

  1. There are 8 blue cables with 32 pin MS connectors that need to be threaded around the AO bench from the back side to the front side. These cables are numbered and need to be plugged into the corresponding port on the patch panel. The cables provide the 100V power and control signals to the DM.
  2. The AOA camera fan needs to be plugged into the outlet labeled AOA Camera Fan.
  3. There are two grey hoses that provide the cooling air flow for the AOA camera. One goes from the AOA fan mounted on the computer rack to the AOA camera side port. The other goes from the top AOA camera port over the top or around the side of the AO bench (threaded so that the hose does not enter the light path and so hoses are between the AO bench frame and computer rack, this allows the light shields to properly be fitted to block stray light).
  4. AOA camera communication cable is a cream ribbon cable that runs from the back of lgs7 to the back of the AOA camera. Align the arrow on the cable connector with the arrow on the camera to make sure the cable is connected in the proper orientation.
  5. AOA camera video coax connect to the back of the AOA camera.
  6. AOA camera power cable is a large 16 pin MS connector that connects to the back of the AOA camera.
  7. AOA camera RS-232 cable is a beige DB9 cable connects from the back of lgs7 to the back of the AOA camera.

  • RJ45 connector for the motor controller needs to be connected to the plastic RJ45-RJ45 junction box.
  • APD signal cables: These 4 thin black cables have small SMA connectors and need to be connected to the APDs (labeled 0, 1, 2, 3) mounted at the bottom center of the south side of the AO bench. These 4 cables originate from behind a panel on the rear of lgs7.

    LGS

    A few additional cables need to be connected for LGS operations that are not necessary for NGS operations.
    1. Uplink Tip/Tilt cables are stored above the TUB, underneath the lowest Laser cabinet. These high voltage coax cables need to be uncoiled and plugged into the back side of the computer rack. The cables are labeled and connect to J807, J808, and J809, labeled X, Y, and +100, respectively.
    2. Photometrics (Slow WFS) camera cable is a 50pin SCSI cable that needs to go from the lgs13 PC to the Phototmetrics camera, which is located in the middle of the back side of the AO bench. The SCSI cable should be cable tied to the large umbilical cable for strain relief and neatness.

    Telco Software

    Even though AO sits at the cassegrain focus we need to use telcontrol prime to set the proper TUB angle and guide matrix.
    1. On shane, start
      telcontrol prime
    2. Set the TUB angle to 359 (Note: NIXIE reading should be 58.00, which corresponds to a 'real' TUB angle of 67 degrees).
    3. Set guide matrix to AO w/ WFS if in NGS mode or AO w/ APD if in LGS mode.

    POCO Software

    1. Start the AO version of the POCO server (see instructions elsewhere). (Running the KAST version will allow everything to work except that E and W buttons in the AO and IRCAL GUIs will move the telescope in the opposite direction - a very undesirable feature).
    2. Make sure offload.tcl is running on shanepc (/usr/local/lick/sbin/offload.tcl). You can use the command
      ps -auxwwwf | grep offload.tcl
      to see if offload.tcl is running.

    IRCAL

    IRCAL, the IR camera used with AO, also needs to be cabled up and powered on for use.
    1. IRCAL's Motor Controller is mounted in the motor control rack.
      1. The power cable should be plugged into the outlet on the motor control rack, back side that is labeled IRCAL Motor Controller.
      2. The motor limit cable (MS connector) and 3 motor control cables (DB9) need to be threaded around the AO bench and connected to IRCAL. The 3 motor cables are labeled 1, 2, and 3 and should be connected with the same numbered motors. The MS connector connects to the side of IRCAL.
      3. The DB25 cable connects to the LIRC Motor Controller (MC) DB25 on the TUB.
    2. IRCAL electronics consists of two units, the power supply and the readout electronics.
      1. The electronics box is attached to the outside of the motor control rack. A power cable runs from the power supply to the electronics box.
      2. There is an additional cable that runs from the electronics box to IRCAL. It is very important to make sure you use a grounding strap to the IRCAL chassis while connecting or disconnecting this cable from IRCAL, as the electronics of the PICNIC array are very sensitive to static and could render the camera unusable. When the cable is disconnected from IRCAL, there is a shorting plug that should be put in place to protect the PICNIC array. The shorting plug is stored in its own space in the middle tier of the AO Alignment Tools box.
      3. There is a pair of fiber optic cables on the TUB that connect to the IRCAL electronics box.
    3. In the ROR computer room the following cables need to be connected:
      1. The black fiber optic pair cable from the TUB connects to ircalbox (the orange fiber optic pair goes to the AO prep room). When properly connected and powered up, the green FO OK LED should be on.
      2. The LIRC MC DB25 cable needs to connect to the back of ircalbox. A null modem is necessary in this cable run for proper communication between ircalbox and the motor controller.
      3. Power up the IRCAL electronics. It's the small rocker switch on the blue power supply box next to the Lakeshore controller in the top front of the motor-control rack.
