Net Name Diagram
+12V B03B (1 ×)
+12V B03C (1 ×)
SRP (Service Reference Protocol) is a software tool that creates a list with all references to signal lines. The list contains
+12VD B03C (1 ×)
+12VD B03H (1 ×) references to the signals within all schematics of a PWB. It replaces the text references in the past printed next to the signal
+1V1 B03E (2 ×)
names in the schematics. These printed references were created manually and are therefore not guaranteed to be 100%
+1V2 B02H (1 ×)
+1V2 B03D (1 ×) correct. In addition, in the current crowded schematics there is often none or very little place for these references.
+1V2-BRA-DR1 B01G (1 ×)

+2V5-LVDS B03D (1 ×)
indicated where supplies are coming from or going to.

+5V-USB2 B01C (2 ×)
A reference is created for all signals indicated with an SRP symbol, these symbols are:

• When there is a black dot on the "signal direction arrow" it is an SRP symbol, so there will be a reference to the signal
ARC-eHDMI+ B04D (2 ×)
ARX0- B04D (2 ×)
name in the SRP list.
ARX0+ B04D (2 ×)
• All references to normal grounds (Ground symbols without additional text) are not listed in the reference list, this to keep
ARX1- B04D (2 ×)
ARX1+ B04D (2 ×)
it concise.
ARX2- B04D (2 ×)
ARX2+ B04D (2 ×) • Signals that are not used in multiple schematics, but only once or several times in the same schematic, are included
ARXC- B04D (2 ×)
in the SRP reference list, but only with one reference.
ARXC+ B04D (2 ×)
ARX-DDC-SCL B04D (3 ×)
ARX-DDC-SDA B04D (3 ×) Additional Tip:
ARX-HOTPLUG B04D (2 ×)
A-STBY B03A (1 ×) When using the PDF service manual file, you can very easily search for signal names and follow the signal over all the
A-STBY B04E (1 ×)
schematics. In Adobe PDF reader:
AUDIO-IN1-L B02D (1 ×)
AUDIO-IN1-L B04A (1 ×)
• Select the signal name you want to search for, with the "Select text" tool.
AUDIO-IN1-R B02D (1 ×)
• Copy and paste the signal name in the "Search PDF" tool.
AUDIO-IN1-R B04A (1 ×)
AUDIO-IN2-L B02D (1 ×)
• Search for all occurrences of the signal name.
AUDIO-IN2-L B04A (1 ×)
AUDIO-IN2-R B02D (1 ×) • Now you can quickly jump between the different occurrences and follow the signal over all schematics. It is advised to
AUDIO-IN2-R B04A (1 ×)
"zoom in" to e.g. 150% to see clearly, which text is selected. Then you can zoom out, to get an overview of the complete
AUDIO-IN3-L B02D (1 ×)
AUDIO-IN3-L B04B (1 ×) schematic.
AUDIO-IN3-R B02D (1 ×)
AUDIO-IN3-R B04B (1 ×)
AUDIO-IN4-L B02D (1 ×)
PS. It is recommended to use at least Adobe PDF (reader) version 6.x, due to better search possibilities in this version.
