Installation Instructions

1.  Attach the box

Attach the MX-232-IO-Box at the mounting position with the cable ports 
pointing downwards (torque 0.4 Nm). Next, remove the box cover (three 
screws).

2. Establish connection to the camera

You need to follow different procedures depending on the connection option:

• 

Option 1 – 

USB

 

– Remove the slim sealing ring of the straight plug of the USB cable*.

 

– Pull the delivered blue sealing ring over the plug, so that the smaller 

opening points into the same direction as the plug's contacts.

 

– Remove blue bayonet catch of the MX-232-IO-Box and pull out 

the blue plug.

 

– Plug the USB cable with attached sealing ring into the MX-232-IO-Box 

and secure the cable using the blue bayonet catch.

 

– Connect the USB cable to the camera (

Camera Manual).

• 

Option 2 – 

MxBus

 

Before proceeding, make sure there is no voltage on the MxBus 

wires!

 

– Cut the MxBus wires to size (2-wire, 0.6 to 0.8 mm diameter). When 

using 

wires without jacket

, strip the insulation of the wires for 5 mm 

and push the wires through the eight-wire plug (right).
When using a 

cable with jacket

, remove the pre-installed eight-wire 

plug and insert the appropriate cable plug (3 to 5 mm or 5 to 7 mm). 
Press the rubber plug into the casing in such a way that the rims 
stick out equally on both sides. Push the cable through the plug, 
remove the jacket on a length of 15 mm and strip the insulation of 
the wires for about 5 mm.

 

– Connect the MxBus wires to the terminals of the MX-232-IO-Box 

using the screwdriver. Make sure to maintain the polarity (see sticker 
in front of the terminal).

 

– Connect the MxBus wires as described in the corresponding manual 

to the MOBOTIX camera or to another MxBus module connected to 
a camera (e.g. KeypadRFID, DoorMaster). Make sure not to exceed 
the overall length of the MxBus wiring of 50 m (55 yd).

3. Connect the peripheral devices

Connect the other wires/cables as required and by using the corresponding 
cable plugs (inputs, outputs, RS232, MxBus).

4. Lock the cable in place

Insert one or two cable ties depending on the attached cables as shown. 
Pull the cable ties tightly around the cables in order to provide strain relief.

5. Mount the cover

Mount the cover back onto the MX-232-IO-Box and affix it using the cover 
screws (torque 0.4 Nm).

Resetting the MX-232-IO-Box

If the MX-232-IO-Box had been connected to a different camera before and not deactivated or reset before 
detaching, the left LED (MxBus status) may blink red after establishing the MxBus connection. In this case, you 
need to reset the connected and activated MX-232-IO-Box to 

factory defaults

:

•  Remove the box cover (three screws).
•  Bridge the contact surfaces below the 

Factory Reset

 label (red circle in figure) 

using a screw driver, for example (both LEDs are flashing red/blue with increasing 
frequency).

•  Only remove the bridge if both LEDs of the MX-232-IO-Box are flashing green 

on/off 3 times to indicate that the process has finished successfully.

•  Mount the cover back onto the box (torque 0.4 Nm).
•  Set up the MX-232-IO-Box in the camera (see 

«Initializing the MX-232-IO-Box»).

Notes

•  The MOBOTIX MX-232-IO-Box is to be used only for providing signal inputs/outputs and an RS232 interface 

(only when connecting to a camera using USB) for MOBOTIX cameras in IP65 environments.

•  For MOBOTIX cameras with MxBus connector and software version MX-V4.1.4.11 or higher.
•  Make sure that you adhere to all relevant laws, regulations and that you fulfill all certification requirements 

for the intended use.

•  Torque for all screws: 0.4 Nm.
•  Press the white cable plug (eight-wire plug or cable plug 3 to 5 mm or 5 to 7 mm) into the casing in such a 

way that the rims stick out equally on both sides.

•  The max. baud rate of the RS232 cable depends on the cable length and on the cross-sectional area of the wires.
•  The length of the entire MxBus wiring must not exceed 50 m/55 yd.
•  Cross-sectional area of the MxBus wires: 0.6 to 0.8 mm (0.8 mm recommended to reduce line losses).
•  Do not use jumper J2; it will be used for future extensions of the MX-232-IO-Box.
