5-11-4 TX Power Supply
5-11-4-1 General Description The TX Power is a switch mode power supply module.  It is used to generate two symmetrical pairs of 
digitally programmable voltages for the  transmitters in the Vivid 7 scanner.
A fixed Probe MUX voltage with either +/- 95 VDC  or +/- 100 VDC, depending on TX Power Supply 
model, is used by the multiplexers in Linear Array  and Convex probes with more than 128 transducer 
elements.
• It is enclosed in a metal frame  that slides into the Card Cage. 
• The module connects to the Motherboard (Backplane) through a 32 pin connector 
• One or two guide pins, located between the two  upper mounting screws, fits into corresponding 
hole(s) in the Card Cage. This “key” is used to pr event it from being plugged into scanners that use 
similar, but not comp atible power supplies.
- The TX Power with one guide pin is used in  Vivid 7 produced with software version v3.x and 
earlier, and without 4D.
- The TX Power with two guide pins was introduced  for use in Vivid 7 with software version v4.0, 
and is needed for all Vivid 7 with 4D.

5-11-4-6 Fuses • Output Power Protection Circuit with these functions:- Protect probe and TX board if a failure make the voltage exceed limits
- Protect the power supply if there is a  failure in probe or transmitter circuit
• A watch-dog disables the voltage  (set it to zero Volt) if the; 
- serial communication with the FEC-2 module stops 
- nominal Power limit is exceeded
- maximum Power limit is exceeded
5-11-4-7 Jumpers and Dip-switches None.
5-11-4-8 LEDs None. 
5-11-4-9 Power Loss A power loss may be due to: 
• The Mains Switch has been switched to OFF
• The Mains cable has been disconnected
• Brown-out
If a power loss occur, a ll AC power distribution within the unit is lost. The Front-End Card Rack stops 
functioning, the perip herals and the monitor also looses its power.
On units with an internal UPS, the Back-End Processor  automatically switch over to the internal battery, 
and the Back-End Processor starts  an automatic power down sequence.

5-12-1 General Description, Top Console on Vivid 7 
NOTE: Vivid 7 PRO is described in  section 5-12-4 on page 5-145.
The Top Console includes Monitor, Monitor Shelf, Speakers and Operator Panel. 
The Console’s movement backwards and forwards and to the sides is made possible by the Frogleg 
unit that links the Top Console to the rest of the S ystem in a flexible multi movement joint. The handle 
(XY-release Handle) that unlocks the Frogleg, is located in the center lower side of the Front Handle. 
The Top Console can also be moved up and down. The handle (Z-release Handle) is located in the left 
grip of the Front Handle. A gas spring inside the sy stem assists in the Z movement. It is actuated by 
pulling the Z-release Handle and at  the same time lifting up or pushing down the Console with some 
pressure to assist up/down motion. 
A flexible harness of electrical and mechanical wir es secures the connection between the Top Console 
and rest of the System.
