User Manual: MBar EX
3. Placement of MBar EX sensor
The sensor should be mounted in the model to a hard surface to prevent accidental pulling out of cables or
pressure tubing. Properly protect the sensor against the transmission of vibrations, e.g. using double sided
adhesive tape. Use pressure tubing properly sized for the required pressure.
Attention! The sensor itself is not mechanically suited for frequent pulling out of the tubing. It is strongly
recommended to have the tubing permanently connected to the sensor. If necessary, disconnect the tubing
further away from the sensor. Failure to do so may damage the sensor.
4. Connecting the MBar EX sensor
The MBar EX has an output marked Ext. and two programmable ports that are labeled as Ext1 and Ext2.
Using the Ext. port of the sensor the data is transmitted to the receiver or to the connected JETIBOX, and it
serves as a power supply as well
Possible functions of the programmable pins
Ext1 Ext2
Disabled Disabled
Expander (by default) Expander (by default)
Logical input No. 1 Logical input No. 2
Connection with the JETIBOX terminal only
The three wire cable with JR connectors can be plugged in into the Ext. sensor connector and then directly to
the JETIBOX (socket with the label Impulse, + ). For power supply use the second input of the JETIBOX with
the (+ ) label, apply a voltage of 5 8.4V. When taking advantage of this type of connection, you must be aware
that no wireless data transfer exists and the measured data is shown directly on the LCD screen of the
JETIBOX. This connection type allows no alert signal generation, because the buzzer is a component of the
transmitter module (non US) which is not connected in this case. Any alert signals are only shown on the
JETIBOX LCD screen.
Connection with a receiver and Duplex transmitter module (non US)
Connect the three wire extension cable with JR plug to the Ext. socket of the MBar. The other end of the
cable is to be connected to the Duplex receiver (also the Ext. socket). The MBar sensor gets its power supply
through the receiver. In order to adjust parameters of the MBar, connect the JETIBOX to the transmitter module
and switch on the receiver and the transmitter.
Connection via Expander
Connect the three wire extension cable with JR plugs to one of the EXPANDER inputs. The other end of the
cable is to be connected to the Ext. socket of the MBar. The Expander enables connection of several telemetry
sensors to one receiver. In such a case the MBar sensor gets its power supply through the Expander and the
Expander through the receiver.
