    Here is the image of socket. Wire (female) side. Maybe somebody faced with same controls.

    Whats is that cable connected to? I've never seen a 2110 with a 37 way circular connector, they always have a 25 way D type for the remote and interlocks.

    That's nothing like any JDSU PSU I've seen before, but it looks remarkably like some late model Melles Griot ion supplies I have, so I'm guessing it's manufactured by Laser Drive as my MG supplies are. You showed a cable earlier, was that cut out of the instrument the laser was taken from?

    Cable not cutted, just detached. If i right understanding you.
    Here is other side of remote cable. Click image for larger version.

    See if it is an SP 261 compatible plug or an ALC / Omnichrome compatible plug... Those are two of the three standards for 37 pin. The other is NEC/Lasos, which is a mess.

    Start with just checking the POWER pins for +/-15V/ isolated signal GND per the pinouts in Sam's FAQ

    Default [SOLVED]

    It's a clear example of "Shit on input = shit on output".
    My PSU actually is Spectra Physics 263-A0602 that I've found out. But some variant of JDSU 2111 PSU with same round 37-pins remote control socket may exist. Also, there is a manufacturer's remote control with analog or digital Amps/mW indicator model 361C that should fit both Spectra Physics 263C and JDS Uniphase 2111 PSUs.
    Now I found a description of pins in very useful Sam's laser FAQ. I just left a paragraph here for information:
    Code:
    SP-263C Remote/Interface Connector
    This is an AMP-style (round) 37 pin connector which is compatible with the Spectra-Physics 361C remote interface. It may also be compatible with the JDS Uniphase 2111 power supply (or at least versions that have the AMP-style round Remote Connector, not documented in the manual).
    
       Pin Number   Signal                  Description
      -----------------------------------------------------------------------------
            1       Reference (Return)      Sensitivity is approximately 5 mW/V in
            2       Reference Input 0-3 V   Power Mode or 5 A/V in Current Mode.

                      is out of regulation.  This open collector signal can drive

                      minimum plasma tube current.  A logic 0 indicates the laser
                      in Run mode.  This open collector signal can drive an status
                      indicator, -20 mA max.
    
           16       Lasing Status (Output) - A logic 0 when referenced to pin 1
                      indicates the laser is drawing current.  This open collector

    Returning to the pins, my remote wire doesn't completely fit Sam's description.

    Pin Description Absent/Present Comment
    1-3 Laser power management + Present
    4 Cable shield/System Ground - Absent in my wire. Not necessary I think
    5-9 Not used +- Pin #6 exist in my actual wire
    10 Regulation status -
    11 +15 VDC -
    12 Interlock Status (Output) + May utilize as Power On/Off indicator?
    13-14 Not used -
    15 Run/Standby Status (Output) -
    16 Lasing status (Output) - What the difference with previous?
    17-18 Not used +
    19-21 15 VDC for User - Not necessary I think
    22-25 Not Used -
    26-27 Current monitor + 0.1 A/V may be meas. by Voltmeter
    28 Not used -
    29-30 Power monitor + 0.2 V/mW may be meas. by Voltmeter
    31-33 Not used -
    34-35 Standby/Run switch +
    36-37 Interlock switch + May use as Power On/Off switch?

    Do you have any idea of the 6th pin? I'm going to repin it to 15 position for monitoring Run/Idle. Also, I want to repin 26-27 pins to 19 and 21 positions to power ATMega with display (as laser power monitor).
    Some suggestions?
    P.S.: Explain to me please, non-native English speaker , what does it mean: "Lasing status" and "laser drawing current". As i understand "Lasing" means "laser emits light" and "laser consumpting power"?
