Wiring | NSO evo2 Installation Manual
Touch screen control
The NSO evo2 may be controlled solely by touchscreen displays. Support is included to
interface with the MO16-T, MO19-T, and MO24-T, and KEPMGB-15T but other screens may also
work, though no offi cial support can be off ered. The MO series monitors require serial (RS422)
connection, whereas the KEP monitor control is connected via USB. By default, ‘USB 1’ and
‘Serial 1’ relate to HDMI 1 OUT, and ‘USB 2’ and ‘Serial 2’ relate to HDMI 2 OUT.
