MOXTEK MAGNUM X-ray Quick Start Manual page 5

(Electrical)
The high voltage power supply has a 10 pin connector
(Figure 1). This connector is used to power, control and
monitor the x-ray tube. Table 1 shows the pin-out for the
connector.
An optional 10 lead ribbon cable is available from
Moxtek (Figure 3). This ribbon cable has a 10 pin IDC
connector on one side that connects to the high voltage
power supply and a DB9 connector on the other end that
connects to the Moxtek FTC-200 controller (Table 3).

Safety Interlock:
To assure safe tube operation, a 5 volt TTL signal is sent
to the power supply to enable x-ray generation. Moxtek
recommends the use of a safety interlock switch when
operating the MAGNUM x-ray tube. Connect the
high voltage enable pin (see Table 2) to the customer
supplied safety interlock switch.
