The NT200 is a digital color image acquisition module designed to transfer color or monochrome image data from video based medical imaging systems to printers and medical workstations.
Image information is transferred to the printing device via removable storage media (Magneto-Optical Disks or MOD), usually for mobile applications.

Safety
Observe the following safety precautions when installing and using the NT200.
Dangerous voltages are present in many system assemblies. The unit should be used only in rooms that comply with recommendations concerning electrical safety when used for medical purposes (as stated in NEC, Title 21 CFR, and UL 2601-1).
Never use the equipment in the presence of flammable anesthetics, gasses or vapors. Some disinfectants and cleaning agents vaporize to form explosive mixtures, and if such agents are used, the vapor must be allowed to disperse before the equipment is returned to use.
Always disconnect the equipment from its electrical supply before cleaning or disinfecting in the near vicinity of the equipment. For routine cleaning, wipe the outside of the cabinet with a damp cloth. To disinfect, use a suitable germicidal disinfectant. Do not spray the cabinet, as this could allow water or other liquids to enter the equipment, causing short circuits or corrosion.
The use of accessory equipment not complying with the equivalent safety requirements of the NT200 may lead to a reduced level of safety of the resulting system. Any patient environment equipment connected to the NT200 must comply with UL2601-1 and IEC 601-1 requirements. Equipment outside the patient environment shall only be connected to the NT200 if it complies with the relevant UL and EN/IEC Standards.
The symbols marked on the equipment denote the following:
Consult accompanying documents. Give special consideration to the Operator’s Manual and Service Manual information marked with this symbol.
Dangerous voltages are present within the cabinet. Never attempt to repair the unit. Only trained personnel may remove the cover of, or otherwise obtain access to the system components. There are no user serviceable parts.
Type B equipment.

Applications
The NT200 is designed for both stationary and portable applications. The images from the image source (ultrasound equipment) can be stored on a removable magneto-optical disk (MOD). The MOD is hand-carried to a print server for printing.

Base Unit
The Base Unit is the box containing the main electronics of the NT200, including the CPU and video processing boards. The Base Unit also houses the MOD Drive and/or the Network Option (the NT200 must have one or the other installed).
MOD Drive
The MOD drive supports both 128 MB and 230 MB MODs. The number of images that can be stored on a disk depends on the recorded image resolution.
NOTE: The use of 128 MB MODs is recommended for compatibility with print
devices.
Remote Keypad
The Remote Keypad has 12 keys and a 2 line x 20 character display. Every operation on the NT200 is enacted from the Remote Keypad.
The display in the Keypad can show the current image number (exam number, sheet number, and image number on that sheet), setup menus and parameters, and system messages and errors. See Figure 2.
Introduction
Figure 2
The keys have different functions depending on the current operation being performed. Keys that can affect the current operation or state will be backlit (active keys). Pressing a key that is not backlit has no effect.

Remote Keypad
Page 10
NT200 Service Manual
A flashing key indicates an operation that is in progress (the last digit of the image being displayed on the remote keypad also flashes) such as Storing (the [STORE] key flashes) or Recalling (the [RECALL] key flashes) an image.
Dual Foot Switch
Separate optional foot switches are used to trigger color or B&W image storage operations.
Functional Description
The NT200 captures an image from the imaging source at the command of the operator. The operator interfaces with the NT200 via either a remote keypad and/or Dual Footswitch.
If the image is stored on a MOD (disk exam), the disk can be hand-carried to the appropriate print device or to another NT200.
The NT200 also provides a video output port for connecting a video monitor. If a video monitor is connected, it will show the same image that is in the NT200 input (Live Mode) or the stored image (Recall Mode).

Installation

The installation of the NT200 depends on the options the unit is fitted with. In general, units can be connected directly to the Ultrasound equipment, since it will calibrate itself for optimum acquisition.
Check that the following accessories were shipped with your NT200 unit. If any part is missing, contact your sales representative.

OCR will recognize white characters on a black background only
OCR will read fixed character spacing only (will not read proportionately spaced characters)
The font in each field to be read by OCR must be the same size
The field position of each field to be read by OCR must be fixed
OCR will work on systems with landscape orientations only
OCR will work on systems running with synchronous sampling
Previous to training, the NT200 must be properly calibrated.

Manual Calibration

The NT200 will be calibrated automatically most of the time. Use manual calibration if autocalibration fails, or to set up the unit for video values other than totally black and totally white.
Before starting manual calibration, display in the imaging equipment an image that contains totally black and totally white regions. Usually test patterns are adequate for this task. (Or display an image that contains the most white and the most black regions desired.)
Color Manual Calibration
Enter the manual calibration menu. From Live mode:
1. Press [MENU] until unit beeps.
2. Press [ ] to advance to Installation menu.
3. Press [YES] until the unit beeps to enter the Installation menu.

Configuration Menu Details
The following section shows a table with the configuration menus in order of appearance on the display. Refer to “Key Actions” on page 29 for a description of the navigation keys.
Some menu items are related to the physical configuration of the NT200. Network related menus will not be displayed unless the Network Option is installed (denoted as NET in the configuration column). Likewise, Removable Disk related menus will not be displayed unless the MOD Drive Option is installed (denoted as MOD in the configuration column).
For each menu item shown in the display, the top line identifies the menu (Setup Menu, Installation Menu, etc.) and the bottom line identifies the menu item or parameter.
The X’s in the display messages are modifiable characters (numbers or letters). The underscored character in the display will flash when the menu is accessed.
The following table has a description of each menu, including the range of possible values, the default and the physical configuration for the menu item to be displayed.
To enter the Menu system, press and hold the [MENU] button until the NT200 beeps.

Sync Parameter Adjustments For Print Troubleshooting

The sync parameters determine how the images are printed.
NOTE: The monitor connected to the NT200 output might compensate for a less
than optimum sync parameter value. Adjust the sync parameters using printed images rather than recalled images.
The sync values for the horizontal parameters are in pixels. The sync values for the vertical parameters are in number of lines. Improper sync numbers can cause unstable images, images cropped at any edge, excessive blank space at any edge, or characters with fuzzy edges.
The
Camtronics 89999-0103, “Sync Parameters for the NT100/NT200 and CAM
by Manufacturer”
manufacturers. In some cases it may be necessary adjust the sync parameter values to optimize the image. If the manufacturer and/or model of the imaging equipment is not listed, follow the adjustment procedure using the default values as a starting point. See Figure 21.

Horizontal Sync Parameters

Adjust HT if the image is unstable (decrease the value for HT) or if the character edges appear fuzzy. The value for HT is slightly larger than HS+HA (HT can never be smaller than HS+HA).

Vertical Sync Parameters
Total of lines (VT)
This parameter defines the number of lines on the monitor. There are two standards for the number of lines:
USA systems, which operate at 525 lines (HT=525). This standard usually applies to any country where electric current is at 60 Hz.
European systems, which operate at 625 lines (HT=625). This standard usually applies to any country where electric current is at 50 Hz.
The relationship is: (2 • V
) + VA + 8 < VT.

This parameter defines the top edge of the image. The default values (factory setup) is usually appropriate. Adjust VS if necessary. See Figure 24.
