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.
3 Reference 3 V Supply Use 100 ohm pot or external source.)
For pot, pin 1 is CCW end.)
4 Cable shield/System Ground
5-9 Not used
10 Regulation Status (Output) - A logic 0 when referenced to pin
1indicates the laser is regulated. A logic 1 indicates it
is out of regulation. This open collector signal can drive
a regulation indicator, -20 mA max.
11 +15 VDC - Regulated voltage for user use, 100 mA max.
12 Interlock Status (Output) - A logic 0 when referenced to pin 1
indicates to pin 1 indicates the interlock loop is closed
and emission is imminent. A logic 1 indicates the interlock
loop is open. This open collector signal can drive an
emission indicator, -20 mA max.
13-14 Not used
15 Standby Status (Output) - A logic 1 when referenced to pin 1
indicates the laser is in Standby mode and operates at
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
signal can drive a status indicator, -20 mA max.
17-18 Not used
19 +15 VDC - Regulated voltage for user use, 100 mA max.
20 -15 VDC - Regulated voltage for user use, 100 mA max.
21 +/-15 V Return
22-25 Not used
26 Current Monitor (Source) - 0.1 A/V from low impedance floating
buffer, may be connected to voltmeter (differential) of 1K
ohm or higher input impedance. To keep noise pickup low,
do not ground either pin.
27 Current Monitor (Return) - Reference for pin 26.
28 Not used
29 Power Monitor (Source) - 0.2 V/mW from low impedance floating
buffer, may be connected to voltmeter (differential) of 1K
ohm or higher input impedance. To keep noise pickup low, do
not ground either pin.
30 Power Monitor (Return) - Reference for pin 29.
31-33 Not used
34 Standby (Source) - Switch to select Standby or Run. Shorted
for Standby, open for Run. Standby mode is 4 A of plasma
tube current. System returns to normal power/current
setting within 20 ms of leaving Standby mode.
35 Standby (Return) - Reference for pin 34.
36 Interlock (Source) - Switch to turn laser on and off. Open
for laser Off, shorted for laser On. Opening and shorting
these pins forces a ~60 second delay before lasing comes
back on.
37 Interlock (Return) - Reference for pin 36.
