5. Input/output signals
The SGI-3, OXI-3 and OXI-3.1 are equipped with an 8-pole DIN connector for connection
to data collection equipment and/or remote control.
Location of pins in the DIN connector seen from the soldering side.
Note: The functions of this connector have been changed in relation to previous
models in some respects
.
