3.6V.
An example of use is, for example, the connection of DO1 (DO2) to the digital
input of another converter (miniELCOR, maxiDATCOM, etc.), which meets
this condition.
Notice
If jumper JP1 is fitted and terminal DO1 (DO2) is connected to a device that
provides a DC voltage greater than 3.6 V on the wire connected to terminal
DO1 (DO2), the device will be damaged!
Attention: this mode reduces the operating ranges of the DO1 and DO2 outputs
(see Table 19)

Note
If the supply voltage is not applied to the U0 + terminal, the DO3 and DO4 outputs are disabled in
the case of ELCOR plus .
