Each PC Workstation on the ARCNET LAN also requires an ARCNET
interface card. The following sections briefly describe the ARCNET inter-
face cards and hub cards. For information regarding applicable ARCNET
interface cards and their installation, refer to “Installing an ARCNET
Card” on page 163.
ARCNET Single Coaxial Input Interface Card
This ARCNET card provides for a single coaxial input. It is used for input
to a BCU from a bus or star configuration (see “Network Topology” on
page 151). This card is required even if a hub card is installed in the
BCU. It has DIP switches and address jumpers that should be configured
prior to installation in the BCU. This card always requires the use of a
tee connector. For a listing of the ARCNET single coaxial input interface
cards and their respective settings currently supported by Trane, see
“Configuring an ARCNET Card” on page 159.
ARCNET Single Fiber-Optic Input Interface Card
This card provides for a single input from a fiber-optic hub card. This card
is required even if a fiber-optic hub card is installed in the BCU. It has
DIP switches and address jumpers that should be configured prior to
installation in the BCU. For a listing of the ARCNET single fiber-optic
input interface cards (and their respective settings) currently supported
by Trane, see “Configuring an ARCNET Card” on page 159.
ARCNET Three Input Coaxial Hub Card
This ARCNET card provides a central point (hub) where you can link one
coaxial ARCNET link to up to two other coaxial links. You can configure
each of these coaxial links in a star or bus configuration. See “Network
Topology” on page 151 for further details. This card has address jumpers
that should be configured prior to installation in the BCU. For a listing of
the ARCNET hub cards (and their respective settings) currently sup-
ported by Trane, see Figure 73 on page 161.
The coaxial hub card does not connect the BCU to the LAN. You must
provide a separate ARCNET single coaxial interface card for this purpose.
The BCU merely supplies the hub card with power. For a list of the ARC-
NET single coaxial interface cards currently supported by Trane, see
Figure 73 on page 161.
Note:
Only ISA ARCNET cards may be used in the BCU because the
BCU does not have a PCI bus.
Note:
Do not use tee connectors on any type of hub card. The coaxial
cable is connected directly to the BNC connector on the hub
card.
