2) Dividing looms into groups as required
•
To network over 200 looms, divide the looms into groups, each consisting of within 200 looms.
•
If the row of looms is long, the network cable length may exceed 100 m. (The network cable must
not be extended beyond 100 m.)
Grouping of looms may make the wiring route study easier.
3) Determining the locations of the computer, router and switching hubs
•
The computer, switching hubs, and the router as network components are precision electronic
devices. They should be installed in places that can be protected from fluffs and condensation or
housed in metal boxes.
•
The power supply (100 VAC or 200 VAC) for the network devices is necessary. Select the loca-
tions where the power supply can be used.
•
Please study while checking the wall and poles to confirm possibility of actual installation.
