X-Ray Machines

This section deals with specific x-ray machines and integration. We are constantly updating this page so if you have any suggestions, please email clockman@soundvet.com with pictures, wiring diagrams, service manuals, etc.

IO Box Integration

The Sound Universal Input/Output (UIO) Box version 3 has several features that allow for easy connection and troubleshooting.

  • Built-in generator integration with 5v relays with prep, exp terminal board
  • Wireless X-speed connection
  • Mountabl

1. Remove the 4 screws on top of the UIOv3 Box and remove the strain relief on the side.

2. Pull your cable carrying the common, prep, and expose signals into your IO box through the hole in the side.

This will connect to the terminal strip labelled

  • Prep
  • Prep (common – can be jumped for 3 wire systems)
  • Expose (common – can be jumped for 3 wire systems)
  • Expose

3. Using the Prep, Expose, and Common signals from your x-ray machine (from the foot pedal or the generator), connect them to your UIOv3 box.


  • 3 wire system (prep, exp, com): use the provide jumper between on the terminal strip between the common connectors
  • 4 wire sytem (prep, prep com, exp, exp com): remove the jumper and and wire your prep and expose common in the center of the strip

4. Replace the top of the UIOv3 Box and replace screws

5. Screw in your Receptor Interface 9-pin connector from the Plate (4343) or Plate Power Box (4336) to the corresponding spot on the IO Box.

6. Attach your Foot Pedal.

7. Plug in your IO Box.

Jumping onto the Console Prep/Exp

In some cases, you may have a sure-prep foot pedal with no separate signals for Com, Prep, and Exp. If you have a console that has a 2-stage prep and expose, you can most often tap onto the console to get the prep, expose, and common signals.


Summit IO Integration

Integrating with a Summit can be done in 2 ways. If you find that you have Sure Prep enable, you will have to disable it before connecting the Sound system.

  1. Foot Pedal Integration
  2. Generator Integration

Summitt S1-S3

Generator Integartion

1. Open up the Generator.

2. Locate the TB4 (may also be TB5) Board on the Summit

3. Connect to the following

  • S1 – common
  • S2 – Prep
  • S3 – Expose

4. Run these connections into the UIOv3 Box to the corresponding connections.

SmartDR – Summit X-ray Integration

Sound SmartDR integrates with newer (Nov 2016 and newer) and older HF (Oct 2016 and older) Summit Generators, allowing for the SmartDR acquisition software to automatically set the KVP and mAs. The generator and the acquisition connect via a serial cable provided with the Generator Integration Kit.

Dell Mini-Tower Acquisition Setup

Insert the Serial Cable from the generator into the open serial cable slot on the Acquisition mini-tower computer. You will Select COM1 in your SmartDR setup.

Summit Int Serial Plugged In

Dell All-In-One Computer

Insert the USB-to-Serial cable into an open USB port. Plug the serial cable into the generator and the other end into the USB Serial cable. Select an open COM Port in SmartDR (not COM1)

Sedecal IO Box Integration

The Sedecal generator connects to the the Prep/Expose switch via the J-15 terminal inside the generator. The Foot Pedal is activated through the tube console through a 3-wire Prep, Exp, Com connection. The easiest place to integrate is using the foot pedal.

Method 1: No Service Pedal

  1. Remove Sedecal foot pedal cover to determine what wires are your Com, Prep, and Expsoe
  2. Cut the foot pedal wire
  3. Integrate the correct Com, Prep, and Expose wire into your Sound IO Box

Method 2: Service Pedal

  1. Remove the Sedecal foot pedal cover
  2. Drill a 1/4″ hole in the back of the foot pedal
  3. Use  quick splice connectors to attach a new 3-wire to your Prep, Com, and Expose
  4. Use cable ties to secure new wire
  5. Integrate your new wires to yourIO box utilizing the Com (jumpered), Prep, and Expose terminal connector.

Placing / Removing the Table Top

Sedecal table tops can be tricky to place or remove in tight spaces. This video shows a trick to getting it on and off. The older Sedecal machines only have 2 sets of rollers on each end. The newer ones have a third set in the middle. I recommend removing this set of rollers

Tomo Mode

The 4030R and 4030E VetPacs systems (the purple clamshell plates) had a direct connection to the Sedecal Generator and utilized the Sedecal Footpedal (attached on the console board). There was no direct “IO Box integration.” In order for this to work properly, the Sedecal had to be set in Tomo Mode.

If you run across an upgrade or system that has wires coming out of the generator and running directly to the computer, you will need to turn off Tomo Mode by putting the machine into config mode. If you can not access config mode by using the console, you will need to enable it by changing a dip switch setting in the generator.

To enable Config Mode in the Sedecal Generator,

  1. Turn off power at the breaker
  2. Open the generator
  3. Locate
  4. Dip Switch 3 UP to turn on Config Mode

Service Manuals

1. Hold the following 3 buttons simultaneously to enter Tomo Mode

  • Empty
  • Full
  • On

Once you release all 3 buttons, you will be in calibration mode.

2. Once in calibration mode your KVP,mAS, and mA will change.

Tomo Mode

  • KVP = 1: number of tubes
  • mAS = 3: Bucky Mode activated

3. Change the mAS (bucky mode) option to 0 to disable Tomo Mode. Your new numbers should read

  • kVp – 1
  • mAS – 0
  • mA – 0

Universal X-ray comes in many different shapes. Many of the newer ones are equipped with a sure-prep feature that allows you to single press the foot pedal to both prep and fire. Please see the Sure-Prep section for information.


The Universal with the tube-mounted console unit can not be modified. There is no true common, prep, and expose, but rather a set of boards.

Universal IO Box Integration

To integrate into a Universal, you will most often need to interface directly with the generator. Most Universals are a 4-wire system, utilizing a separate prep common and expose common.

Many of the newer machines require a 7/16″ wrench to remove the 2 1/4″-20 screws in the bottom corners of the pull-out face panel

1. Locate SW Prep SW Expose terminals on the TB5 board. This may require removing the 1/4″ bolt inside the cabinet to reveal the TB5 board.

Universal board location

2. Attach a wire to each terminal with the SW being a Prep. You will have 2 separate Prep wires.

3.Pull other end of wire through the back of the generator and wire accordingly into the UIOv3 box.

NOTE: Manually test your wires before integrating into the IO box.

In order to prep and fire you x-ray machine, you must make sure the . (dot) in the mAs is SOLID. If it is blinking, your x-ray machine is not ready to fire. If you try and prep while the dot is blinking, you will get an E9 error.

There are several variations of Bennet machines. If you have  a 2 stage foot pedal you can jump into it for your prep, exp, and common signals. There are some systems that do not have a label on them. One of these is the wall mounted unit from the 90’s.

  • 1 = Prep
  • 2 = Common
  • 3 = Expose


Transworld machines can often be difficult to integrate due to a lack of a foot pedal, a common signal, or a single stage foot switch. For a detailed description of integration, click here.

This generator terminals trip only has a Prep and Expose

A stand-alone console like the one pictured here is often a good indicator that you will need to solder into the console prep and expose buttons in order to make get your prep, expose, and common signals. This system would have a 4-wire connection with a separate common for both the prep and expose.




Fischer X-Ray Machines can look daunting. Though they are limited, they are easy to integrate and operate once you know how. The video below shows an overview of how to use a Fischer X-ray machine, including turning the collimator. The collimators on a Fischer can be seen elsewhere, and were fairly popular in the late 70’s and 80’s.
