Communications Network Connections.
There are two RS485 communication networks connected to a DC68K, an internal
network connected to the PACK-IO controllers and an external network to the Storescan
III.
Note:
These two networks are incompatible and must not be connected to each other.
9
Ensure the correct cable (BELDEN 8762 or equivalent) is available.
9
When stripping the cable, remove about 25mm of outer PVC and peel the
screening foil back to the outer PVC, cut off the screening foil. The white
or clear insulated conductor is 'A', the black insulated conductor is 'B' and
the non-insulated drain wire is the screen. Strip about 5mm of insulation
from the 'A' and 'B' conductors. All but the end of run serial unit require
both an in and an out cable wired into the same terminals. Twist the
appropriate conductors together before fitting to the orange plug. Ensure
the wires are in the correct position.
9
Only 30 serial units are permitted to share each of the communication
cables (the DC68K counts as 1 unit per run).
8
DO NOT:
Run power cables in the same tray or trunking as
communications cable.
8
DO NOT:
Connect the cable screen to earth. (The connection is pre-made
inside the Storescan III panel).
