There is only one LCD for a shelf of multiple NTUs. To select the NTU
for which you want to display details on the LCD, press the appropriate
DISP
button. A yellow
LA
lamp confirms the NTU you’ve selected.
The LCD will continue to show information from that NTU until you
press another
DISP
button.

Cabling distance
To achieve the best performance from your circuit, the cabling distance
between the NTU and any data terminal equipment (DTE) shouldn’t
exceed 180 meters. If you relocate the DTE at any time, please ensure
that you don’t exceed this distance.
