DDC
To make your installation easier, the monitor is able to Plug and Play with your system
if your system also supports DDC protocol. The DDC(Display Data Channel)is a
communication protocol through which the monitor automatically informs the host
system about its capabilities, for example, supported resolution and corresponding
timing. The monitor supports DDC1 and DDC2B standard.
Installation
To install the monitor to your host system, please follow the steps as given below:
Steps
1. Use the VGA cable that provides D-SUB 15P connector and connect to the 15-pin
connector on the VGAcontroller card.
2. Use the S-Video cable that provides S-Video connector and connector to the S-
Video port on the video source device (ex. VCR, Camera system)
3. Use the BNC cable with the BNC to RAC adapter that provides composite video
connector and connector to the composite video port on the video source device.
4. Use the RS-232 serial cable that provides DB9 pin connector and connect to the 9-
pin connector on the source device for touch screen communication. (Optional)
5. Connect the DC power to the DC power connector on the monitor.
6. Connect one end of AC power cord into the AC Adapter and the other end to AC
power outlet.
7. Then turn the computer on and then the monitor.
8. If the monitor still does not function properly, please refer to the troubleshooting
section to diagnose the problem.

Screen Position Adjustment (with optional stand)
In order to optimize the best viewing position, you can adjust the tilt of the monitor by
using both of your hands to hold the edges of the monitor as shown in the figure below.
The monitor can be adjusted up to 30 degrees as indicated by arrow below.
Connecting the Power Cord
• Check first to make sure that the power cord you use is the correct type required
for your area.
• This monitor has an universal AC adapter that allows operation in either AC 100
- 240 Vac voltage area. No user-adjustment is required.
• Plug one end of the power cord to the AC adapter, plug another end to a proper
AC outlet.
The cord set should have the appropriate safety approvals for the country in which
the equipment will be installed and marked HAR.
For 120 volt Applications, use only UL Listed detachable power cord with NEMA
configuration 5-15P type (parallel blades) plug cap. For 240 volt applications use only
UL Listed Detachable power supply cord with NEMA configuration 6-15P type
(tandem blades) plug cap.

Power Management Function
The monitor is equipped with the power management function which automatically reduce the
power consumption when not in use in three power level modes.
• Stand-by Mode
The monitor goes into stand-by mode when the horizontal sync signal is off for about 10
seconds. In this mode, the screen goes off and the power LED blinks for 1 seconds On and 1
second Off. The screen is displayed after the horizontal sync signal is restored.
• Suspend Mode
The monitor goes into suspend mode when the vertical sync signal is off for about 10 seconds.
The power consumption during this is less than 8 W. In this mode, the screen goes off and the
power LED blinks for 1 seconds On and 1 second Off. The screen is displayed after the vertical
sync signal is restored.
• Off Mode
The monitor goes into power-off mode when the vertical and horizontal sync signals are off for
about 10 seconds. In this mode, the screen goes off and the power LED blinks for 1 seconds On
and 1 second Off. The screen is displayed after the vertical and horizontal sync signals are
restored.
Power Management System
The AMM15TK2 Series Medical Monitor complies with the VESA DPMS power management
proposal. The VESA DPMS proposal provides four phases of power-saving modes by detecting
the horizontal sync signal as shown in the table blow.
Mode
DC Input Power (monitor only) AC Input power (incl. AC adapter) LED Status
On 28.0 W max. 37 W max. Steady Green
Standby 4.5 W max. 6W max Blinking Green
Suspend 4.5 W max. 6W max Blinking Green
Off 4.5 W max. 6W max Blinking Green
When the monitor is power saving mode or detects an incorrect timing, the screen will be blank
and power LED indicator will blink.
