Control Bus Adapter
For control buses for the Human Interface Station (HIS) and Compact Field Control Stations for
FIO (AFF50S/AFF50D), use V net (10BASE-2) cables. For control buses for field control stations
other than the Compact Field Control Stations for FIO, use V net (10BASE-5) cables. The
cable conversion adapter is required to connect these two types of cable, which are of different
diameters.
The figure below shows how 10BASE-5 cable and 10BASE-2 cable are connected.

Figure Control Bus Adapter (YCB147)
The thickness and weight of the two types of cable are different; the control bus adapter (rack
mountable type shown above) used to connect them.
• The V net cable (10BASE-2) is low less, so mount the adapter so as to minimize the length
of 10BASE-2 (which is more lossy).
• For ease of maintenance, mount the adapter above floor and near the HIS.
• Do not mount the adapter in a passageway or aisle between equipment.
• The rack mountable type illustrated above can be mounted in a rack or console.
