CSIP Level 1 General Information: Transducers
Transducers
Refer to Section 15, “Transducers” for a list of and other information about the transducers.
Physical
Description
Refer to Section 14, “Parts” for illustrations of the following.
Frame
The frame provides the primary structural support for the system. It has a one-piece weldment.
The frame provides the mounting base and swivel mechanism for the monitor. The control panel
articulation mechanism also mounts to the frame. All four casters are swivel mounted, and the
right rear caster has a swivel lock. Front casters have brake locks. The swivel-lock pedal (right)
and the brake-lock pedal (left) are on the front of the system where the user can easily activate
them.
Acquisition Card Cage
Four slots of the Acquisition Card Cage are dedicated with appropriate shielding for Channel
Boards. Two additional shielded slots are available for the NAIM PCB and an FEC PCB. External
connections are provided through connectors mounted on brackets attached directly to the card
cage modules to eliminate cabling to remote connectors.
Cooling air flows in at the bottom of the four Channel Boards, up to a plenum above the card
cage, down past the NAIM and FEC, and exhausts through an area in the bottom pan below the
NAIM and FEC PCBs. The Acquisition Card Cage is illustrated in Figure 14-36.
Platform Card Cage
The Platform Card Cage contains the Host and SIP motherboards, both of which are located on
slide-out drawers and contain other PCBs. The card cage is designed to allow for future mother-
board, power-supply, and fan-module upgrades. Rear-mounted fans provide forced-air cooling.
Cooling air flows in at the bottom left of the cart, through the air filter, up past the Host CPU
