Analog Display Signals

Signal Name

Type

Description

RED

RED Analog Video Output: This signal is a CRT Analog video

output from the internal color palette DAC. The DAC is designed

for a 37.5 ohm routing impedance, but the terminating resistor

to ground will be 75 ohms (e.g., 75 ohm resistor on the board,

in parallel with a 75 ohm CRT load).

RED#

RED# Analog Output: This signal is an analog video output

from the internal color palette DAC. It should be shorted to the

ground plane.
