2.2.7 Using MxBus Modules
The MxBus camera connector is located under the housing
cover (clamps 5 and 6 of the screw clamps) and allows the
operation of additional modules for expanding functionality
(e.g. connection of an MX-GPS-Box for determining time
and position). MxBus was optimized specifically for the use
of existing two-wire cables.
The terminal connector has two connectors to connect an
MxBus module (other MxBus modules can then be connected
from there). The length of the entire MxBus cable may not
exceed 50 m/55 yd.
Note
The MxBus wires that are to be stripped at the end should always be fed into the
camera through appropriate plugs before mounting. If
the single wire plug is used, one wire must be pushed
through a hole in the plug.
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 = –)
Nach dem Anschließen eines MxBus-Moduls muss zunächst der MxBus selbst (sofern
noch nicht geschehen) als auch das Modul selbst in der Benutzeroberfläche der
Kamera im Browser in Betrieb genommen werden (

Erweiterungen verwalten
bzw.

).
2.2.8 External Audio Support (Microphone/Speaker)
The camera connector for an external microphone and an
external speaker is located under the housing cover (clamps
1 and 2 of the screw clamps for microphone, clamps 3 and
4 for speaker).
An external microphone (red box) and an external speaker
(red box) with the following technical data can be connected
on the terminal connector:
•

s
= 2.0 V, R
