48 PI-MAX/PI-MAX2 System Manual Version 5.F
Cable Connections
WARNING! All of the system components must be
turned off before connecting or disconnecting cables.
The following cabling configuration is used when operating in Shutter Mode. If the
system includes a spectrograph, see your spectrograph manual for information on the
spectrograph’s cabling requirements.
1. Connect the PI-MAX to Controller cable.
PI-MAX: Connect cable 6050-0336 from the Power/Signal connector on the
back of the PI-MAX to the Detector connector on the back of the Controller.
PI-MAX2: Connect cable set 6050-0449 as follows. Connect cable 6050-0492
from the Signal connector on the back of the PI-MAX2 to the Camera Signal
connector on the back of the Controller. Connect cable 6050-0493 from the
Power connector on the back of the PI-MAX2 to the Camera Pwr connector on
the back of the Controller.
2. Connect the Controller-to-Computer Interface cable.
PI-MAX: For standard PI-MAX systems, the Controller-to-Computer interface
type is determined by the Interface card (TAXI or USB 2) installed in the
Controller.
TAXI Interface: Connect serial data cable (6050-0148 CE) from the ST-133
SERIAL COM connector to the computer’s Princeton Instrument (RSPI) PCI
Serial Interface card connector.
USB 2 Interface: Connect the USB cable (6050-0494) from the ST-133
USB 2.0 connector to the computer's USB 2.0 Interface card connector.
PI-MAX2: PI-MAX2 systems use the TAXI communication protocol. Connect
the TAXI serial data cable (6050-0148 CE) from the ST-133 SERIAL COM
connector to the computer’s Princeton Instruments (RSPI) PCI card connector.
3. If the system includes a PTG, no other cable connections are required for operating in
Shutter Mode. Procedures for operating with a PTG or a DG535 in Gate Mode are
included in the appropriate Gated Operation chapter.
Before Turning on the System
1. Set the PI-MAX MCP On/Off switch to OFF.
2. Imaging application: Have the lens stopped down to its smallest aperture (typically
f/16). For all experiments, it may be advisable to initially have the intensifier covered
with a black cloth and/or a lens cap over the lens, as well.
3. Spectroscopy application: Set the spectrograph entrance slit width to minimum
(10 µm if possible).
