Installation Overview:

The SC-12 Core Hub is a combination of a BUS-012 Hub and a SC-12 Core Skipper. It is a
BUS-012 Hub with a SC-12 Core Skipper embedded in it. The SC-12 Core Hub performs
several critical functions; 1) it supplies clean, filtered power to Skip-Line devices, and 2) it is the
communication hub for all Skip-Line products, 3.) it maintains the active skip cycles and holds
essential settings.
An SC-12 Core Hub or SC-12 Core Skipper MUST be properly installed to use the Skip-Line
SC-12 system.
Every vehicle requires at least two BUS-012 hubs (or a BUS-012 Hub and SC-12 Core Hub).
Skip-Line utilizes the proven and reliable CAN bus protocol, which requires two termination
points. The BUS-012 Hub and SC-12 Core Hub acts as those terminal points. Multiple Hubs
work together to create a communications network using CAT5 cables.
For more information on CAN Bus, here's an interesting video: ​
Each Hub requires it's own +12V and GROUND connections from a battery source.
Recommended location:
Front Hub (BUS-012):
The recommended location for the BUS-012 Hub labeled "Front Hub" is inside the front
cab of the vehicle. Mount in a location where CAT5 cables can be ran from dash-mounted
accessories. Common locations include inside the front console or on the back wall.
Rear Hub (SC-12 Core Hub):
The recommended location for the BUS-012 Hub labeled "Rear Hub" is inside the center
console or main rear cabinet of the vehicle. Mount in a location where CAT5 cables can be ran
from SC-12 Masters and output boxes.
Mid Hub(s) (BUS-012):
On advanced striping vehicles, mid-hubs are often used. They are not terminated like
Front and Rear Hubs. Place these where convenient (such as in a mid-deck enclosure)

  • Page 2 Mounting: The SC-12 Core Hub comes with two DIN clips on the device for top hat DIN rail mounting. Skip-Line does not supply DIN rails, so please contact your preferred distributor or order DIN rails online. Use Top Hat DIN Rails: EN 5022 35mm x 7.5mm...
  • Page 3 5 meters (16.4 ft). If a device is properly connected to an SC-12 Core Hub or BUS-012 Hub, the large green port light should be illuminated to indicate the device is pulling current. The CVO-312, DL-12, and CPR-212 Paper Tape Printer all have separate power sources and will not cause the port light to illuminate.
  • Page 4 Skip-Line. Leads are included with the 2-pin power plug for convenience. The red with is for +12V, and the black wire is to GND. The plug positions are also labelled on the BUS-012 Box. Recommended wire size for +12V and GND to the SC-12 Core Hub is 18-20 gauge wire. Fusing: Recommended fuse size for the SC-12 Core Hub is 10 amps.
  • Page 5 Pin C: Yellow Pump Stroke Sensor Input (NPN). This is an opto-isolated input from a pump stroke sensor (limit switch, pressure switch, flow meter, etc). The SC-12 Core Hub is looking for a grounding (NPN) signal from the sensor.
