Each scanner channel supports as many as 32 physical adapters. Use
1770-CD (or Belden 9463) cable.
Connect a remote I/O network using a
daisy-chain or trunkline/dropline configuration.
Table 2.B
Total number of devices the scanner supports
In this mode: the maximum number
of logical racks per
channel is:
and the maximum
number of physical
adapters per channel is:
SVĆcompatible 8 16
SVĆsuperset 16 32
Important: The maximum cable length for remote I/O depends on the
transmission rate. Configure all devices on a remote I/O link to
communicate at the same transmission rate.
Table 2.C
Choose the correct cable length based on the link's communication rate
A remote I/O link using this
communication rate:
cannot exceed this
cable length:
57.6 kbps 3,048 m (10,000 ft)
115.2 kbps 1,524 m (5,000 ft)
230.4 kbps 762 m (2,500 ft)
For proper operation, terminate both ends of a remote I/O link by using
external resistors. See Table 2.D for information on whether to use a 150
W
or 82
W terminator.
