Power supply

The original power supply is roughly:

  • 12V in?
  • Dual channel
  • Power-one DGP12U5D5, WTT250IG
    • Outputs +/- 5V
    • Is the -5V rail used?
    • Seem to output 5.3 or 5.4V
  • LM317
  • So basically: 12V DC is converted to just above 5V. Then a linear regulator smooths the last remaining bit down to 5V


Weidmüller-4 Wire color Volt Note
1 Blue 5.11 Ground?
2 Green 0 -5V?
3 Black 0 -5V?

Perkin-elmer_xrd-1640_an19-ets-lp

"The MX-20 had an Perkin Elmer panel sensor with parallel output to an SCSI PC interface board. It can do medium sized boards, up to 10" x 12"...The P-E sensor that came with my MX-20 was not it's original sensor. My MX-20 was non-digital, just a film based one (or phosphor plate based). The P-E had a low voltage differential, parallel, output that was sent through a cable to a PCI frame capture board. The board (made by Perkin Elmer) looked like a SCSI interface to the PC. The sensors are available on eBay, sometimes for a good price, but I've not seen a complete system, sensor, power supply, cables, interface card, and software, in a long time. A sensor is on eBay now, see"
