Length and color
With length of 1800mm, black color.
2.2.2 SIGNAL INTERFACE
(1) Analog input
Pin assignment
See Appendix 1 – Analog connector
Level
0.7 volt ± 5%
Impedance
75 ohm. TDR scan needed for both D-SUB cable and
interface board.
(2) TMDS input
Pin assignment
See Appendix 1 – DVI-D Connector
Level
600mV for each differential line.
Impedance
50 Ohm. TDR Scan needed for DVI cable and interface
board.
(3) Video input
Pin assignment
See Appendix 1 – Video connector
Level
(S-VIDEO) Y input: 1 volt (p-p)
(S-VIDEO) C input: 0.286 Volt (p-p)
(COMPOSITE) 1 volt (p-p)
Impedance
(S-VIDEO) Y input: 75 ohm
(S-VIDEO) C input: 75 ohm
(COMPOSITE) 75 ohm
(3) Sync input
Type
Monitor accepts separate Horizontal, Vertical sync,
composite sync, and SOG.
Level
Monitor accepts positive and negative sync. signal from
both 3.3V and 5V TTL families. Inputs sense a logic 0
when the input absolute value is 0.8 V or less and logic 1
when the input absolute value is 2.3V or greater.
Impedance
2.2KOhm min (pull down)
(3) Signal cable
Analog
Detachable, shielded 2.0 meters (6.67 ft), D-SUB 15P
male connector, with blue connectors, thumb screws and
black color.
Digital
Detachable, DVI-D, white connectors, 2.0 meters (6.67
ft) and black color.
Video
S-VIDEO, COMPOSITE-video, w/o audio. Cables are not
included.
(4) Abnormal signal immunity
The monitor cannot be damaged by improper sync, timing
pulse duration, or absence of sync, or abnormal input
signal amplitude (video and/or sync too large or too
small), or any other anomalous behavior of a graphics
card or video generator when changing modes, or when
any combination of input signals is removed or replaced.
Additionally, under these conditions, the monitor cannot
cause damage to the source.
(5)Warm-up time to stabilize the I/F setup
Image is considered to be ready for correct position and
timing adjustment after 3 minutes maximal warm-up time.
2.2.3 MODES AND TIMING
(1) Synchronization range
Horizontal frequency range: 31 to 80KHz
