Connecting Mxbus Modules - Mobotix D15D Manual

First Installation Steps
10. Secure the cable : Properly lead the cable through
the cable guides at the outer rim of the housing
and make sure that the outer shell can be properly
mounted later on.
11. Attach the outer shell : Hold the outer shell so that
the round hole of the shell is positioned over the PIR
sensor of the camera. Gently press the shell into the
shell's seats in the camera housing. Old outer shells
(D10D, D12D) may no longer be used!

2.3.5 Connecting MxBus Modules

The MxBus connection of the camera is located under the
cable cover and enables additional modules to be operated
to extend the functions of the camera. MxBus was optimized
specifically for the use of existing two-wire cables.
The white (detachable) MxBus connector has four connec-
tions (each of which is blue/red or +/-):
• 2 MxBus inputs to connect the D15D to the MxBus cable
• 2 MxBus outputs to connect an MxBus module to the D15D
The MxBus wires that are to be stripped at the end should ideally be inserted into
the camera before installation. In the process, every wire
(coming from the housing floor) should be pushed through
an elastic sealing membrane.
Do not mix up the polarity of the cables during installa-
tion. Select a consistent cable color for +/- in the entire
MxBus system (for example, red = +, blue = -).
After an MxBus module has been connected, the MxBus itself must be started in
the camera's web-based user interface (if this has not been done yet) as well as the
actual module (Admin Menu > Manage Hardware Expansions or MxBus Modules).
