This manual is designed to assist the user with installaon, setup and operaon of the ScaleOR and its associated
displays. A list of displays that may be used with the ScaleOR is in the Compable Displays secon under General
Informaon on the following page.
A numbered tab on the side of the page denotes the beginning of a secon.
About This Manual
Intended Use:
This device is intended for use in a medical environment to deliver high quality video and graphic images.
Contraindications:
This device may not be used in the presence of flammable anesthecs mixture with air, oxygen or nitrous oxide.
Also, it is not intended for life support applicaons.
No part of this product may come in contact with a paent. Never touch the product and a paent at the same
me.
Warning:
Because invisible laser radiaon may be emied from the aperture of the port when no fiber cable is connected,
avoid exposure to laser radiaon and do not stare into open apertures.
For mission crical applicaons, we strongly recommend that a replacement unit be immediately available.
Intended Use and Contraindications

Installaon:
ScaleOR units may be stacked on a equipment carrier, a surgical cart or mounted in a standard 19” rack.
Ensure that the air vents are not blocked.
Power Supply:
ScaleOR with DVI and SDI connectors — The provided power supply, Ault and SL Power Electronic Corp Model:
MENB1030A1200C02 12VDC, includes 4 interchangeable wall plug adapters. An alternate power supply
GTM91120-3024-T3A, 24VDC. Drawings of the power supply, its adapters, and adapter installaon informaon
are on page 8.
ScaleOR with DVI and HDBaseT (HDBT) connectors — The HDBaseT connector is Power over Ethernet (PoE)
compable and can be used to power the ScaleOR. An oponal power supply is available.
Compable Displays:
1. HD displays with a DVI input.
2. HD displays with HD-SDI or 3G-SDI input.
3. HD displays with HDBaseT input.
4. HD displays with Fiber Opc input. Note: The ScaleOR Fiber Opc output is an oponal feature.
Control Opons:
The ScaleOR may be controlled from:
1. The keypad on the front of the ScaleOR. Using the keypad requires that the ScaleOR be connected to a
display.
2. A PC via the ND-OS port. See Serial Port Setup and Test on page 16.
The NDS Unified Serial Commands (P/N 60A0156) document contains a complete set of serial commands for the
ScaleOR. Please contact your NDS sales representave for details.
General Information
The ScaleOR accepts 1 of following 4 input modules:
DVI-D
SDI
VGA
S-Video / Composite
The ScaleOR is has two opons of fixed output connectors:
DVI and SDI
DVI and HDBaseT (HDBT)
The drawings on pages 3 and 4 show the locaons of the two versions of fixed output connectors and the input
module.
The output mode (resoluon) may be selected using the DIP switches located on the boom of the ScaleOR (see
Output Mode Switch Sengs table on page 5).

HDBaseT and DVI video outputs. The HDBaseT port is Power over Ethernet (PoE) compable and should be
used to power the ScaleOR HDBaseT.
NOTE: The PoE port supplies the ScaleOR HDBT power, as the default power source. The ScaleOR HDBT
can be powered using the wall adapter, as an oponal power source.
The ScaleOR with fixed DVI and HDBaseT output connectors is shown below.

Electrical Symbols
Output Mode Switches
The Output Mode Switches, accessible on the
underside of the unit, allow the user to select
1 of 46 output modes. The Output Mode
Switch Sengs table on the following page
shows the switch sengs required to select a
given output mode. Seng the output mode
from the On Screen Menu (OSM) requires that
all switches be set to off.
Power Switch:
The Power Switch symbol is shown to the le.
The power switch is push on / push off and is shown below the Power Switch symbol. When the
switch is off, the ring around the center poron is white. When the switch is on, the center
poron is depressed and the ring is illuminated blue. The illustraon shows the switch in the
ON state. When the ScaleOR is turned on the blue ring flashes at the rate of 5 flashes per
second for 15 seconds then, becomes steady when a video signal is detected. If a video signal is
not detected the ring connues flashing at the rate of 1 flash per second.

Power Supply and Wall Adapters
The power supply is shown with the US wall adapter installed. To exchange the adapter, proceed as
follows:
The ScaleOR with fixed DVI and SDI output connectors uses the power supply as the power source.
The ScaleOR with fixed DVI and HDBaseT output connectors uses Power over Ethernet (PoE) through the
HDBaseT port as the default power source. An oponal power supply is available.
Place the power supply on your work surface as shown.
Press and hold the buon labeled PUSH.
Twist the adapter 1/8 turn toward the OPEN arrow, and li it off the power supply.
Select one of the provided wall adapters.
Align the tabs on the boom of the adapter with the notches on the power supply and place the adapter on
the power supply. Press the adapter down and twist it toward the LOCK arrow unl it clicks into place.

Startup
Connect one of the ScaleOR outputs to a compable monitor. Connect a video source to the ScaleOR input.
Press the power buon located on the front panel of the ScaleOR. The illuminated blue ring on the power
buon flashes for 15 seconds then, when a video signal is detected, becomes steady. If a video signal is not
detected the ring connues flashing.
The NDS logo is displayed on the monitor unl the ScaleOR inializaon is complete. At which me the
illuminated ring stops flashing, if a video signal is detected, and becomes steady blue. At this me an image
of the video signal connected to the ScaleOR input is displayed on the monitor.
If the ScaleOR has been turned on for more than 15 seconds and a video signal is not detected the blue ring
is will flash at the rate of 1 flash per second.
