HAMAMATSU PHOTONICS L7902 (head) & C8033-01 (controller)

Pony DR2 controller

"for PXG-090W" Testing with L7902 tube (100 kV, 250 uA, 24V, 100W)

ROM implies this is a rebranded Hamamatsu C8033-11

note other listing: "Hamamatsu L7901 (C8033) X-RAY100 Control Unit"

Couldn't get x-ray on. While interlock1 came shorted, interlock2 is not. Suspect that is the issue and a yellow light will come on

Bring up summary (Pony DR2):

• Unit off
• Close both interlocks
• Rotary switch left / "OFF"
• Turn key to power on
• Interlock light should be yellow indicating both interlocks are closed
• Move rotary switch to middle / "ON"
• Will slowly warm up to 20 kV. Voltage will be displayed
• Will sit here for 5 to 10 minutes. AGING light should be on
• Will slow start ramping up voltage past 20 kV. I started detecting x-rays at this point, although I shut off only at maybe 35 kV

serial

25 pin serial. Used a DB25 to DB9 adapter and was able to get the message "ERROR" when I pressed enter

interlock1

2 wires. Came with shorting plug

Internally appear to go to J1

Why isn't interlock1 and interlock2 in series? Do they serve different purposes?

interlock2

4 wires used in case

• 1: red
• 2: orange
• 3: white
• 4: gray

Red and orange go to J11 near large MATSUSHITA relay

Think white and gray go to J9 along with a few other wires

Came with adapter cable HCN21A

• black
• red
• white
• white
• male pins
• goes to another cable
• 12V across white-white
• shorted white-white and interlock light illuminated!

Internals

SW1: all LEDs on front light when pressed. No serial output

MCU: TMP96C141BF
