User Manual: MBar EX
Ext1 Mode, respectively Ext2 Mode – port Ext1, resp. Ext2 can be configured to several functional
alternatives:
Off – the port has no function.
Expander – it is possible to connect any sensor to the port (sensors using JETIBOX, Duplex EX and
EX Bus protocols are supported).
Log. input – the port will be switched to the digital input mode. Detected value (log. 1 or log. 0) is
then available through EX telemetry and e.g. in the DC/DS transmitters it is possible to assign any
action on the basis of the sensor logical input.
Voltage threshold levels table Voltage range
Log. 0 0 – 1V
Log. 1 1.9 – 3.3V
Pressure high alarm - adjustment of the signal representing high pressure. If the measured value exceeds the
set value, the alert will be activated.
Pressure low alarm - adjustment of the signal representing low pressure. If the measured value is lower than
the set value, the alert will be activated.
Beep pressure alarm – adjustment of one of the Morse code letters, which represents exceeding the set
pressure alarm by the sound from the Duplex Tx transmitter module. (EU only)
MBAR MENU: SERVICE
Factory Defaults - by simultaneously pressing the arrows R and L (right and left) for several seconds the factory
settings of the Mbar EX are loaded.
6. Setup via DC/DS transmitters
MBar EX sensor can be easily configured via any DC/DS transmitter. If
you switch the paired receiver to the EX Bus mode and you connect the MBar
EX to its Ext. port, the device will be detected automatically and then might
be configured in the menu Model → Device Explorer.
Notice: For proper function the transmitter version at least 2.20 (or
newer) and the receiver version 3.14 (or newer) is necessary. Further,
make sure that in the Devices folder of your SD card there is a
configuration file MBAR.bin.
On the main screen there is a general menu of available possibilities, actual
pressure and temperature, also measured maximums and minimums. The
minimum and maximum values can be reset manually in the menu or
using a driver of the transmitter.
