When cables are qualified for all bedsides and central station locations,
remove Tester and Injector.
Install Local Distribution Cables
Installation of local distribution cables (LDC) is the responsibility of
Agilent Technologies service personnel. Refer to “SDN Installation
Restrictions and Limitations” on page 8-4.
Local distribution cables (LDC) are used for local series connection from
the wall box to the instruments downstream. Up to two (2) separate
instruments may be connected together via LDCs to each wall box—one
patient per branch.
The local distribution cables are supplied in four standard lengths to meet
most installation requirements. Unique keying along with color-coding
connectors prevent erroneous cable connections. Each connector contains
a metal retaining ring that holds the LDC cable to the connector receptacle
to prevent accidental disconnection and to provide continuous shielding
and ground path. The standard length LDCs are listed below.
Table 8-2: Standard Length LDCs
The variable length LDC is available to meet the installation requirements
not fulfilled by the standard length LDCs. The variable length LDC is
terminated on one end with a standard gray color-coded connector and
open on the other end. This open end allows the cable to be cut to any
