Cables, Wall Boxes, and Faceplates
Branch Cables
There are three types of branch cables that are permanently installed to
provide long distance connection between the ACC and the wall box; the
standard System Distribution Cable (SDC), the Extended System
Distribution Cable (XSDC), and Category 5 Unshielded Twisted Pair
(UTP).
The length of Unshielded Twisted Pair runs must be less than 90 meters
(295 ft.). The length of each standard SDC must be less than 152 meters
(500 ft.). The length of each XSDC must be less than 304 meters (1000 ft.).
Only two XSDC runs are allowable per ACC. Branch cable runs must be
continuous; no splicing or mixing cable types is allowed.
Local Distribution Cables (LDC)
The SDN allows ease and flexibility of user placement of instruments.
Local distribution cables (LDC) must be used for local serial connection
from the wall box/face plate to the instrument, and to other instruments.
The LDC allows bedside instruments to be easily interchanged simply by
connecting them to their new locations.
Wall Boxes and Face Plates
Wall Boxes: only standard size, NEMA, single- or dual-gang, switch wall
boxes with conduit knockouts (KOs) may be used. The depth of the wall
box must be at least 7.0 cm (2.75 in). Wall boxes are usually supplied by
the customer; however, two types are available from Agilent Technologies.
Face Plates: Pre-punched, NEMA, single- or dual-gang faceplates for the
SDN; SDN on UTP US and European wall boxes. Faceplates are included
with the wall box connector kits.
