Series 200 Data Link Cable
This cable contains only data conductors and is used only to interconnect slave ACS racks or mini-ACS
racks to master ACS racks or mini-ACS racks. Data are carried on two individually shielded pairs with a
common drain wire. The capacitance of the cable is very low, allowing the cable to be run for long
distances with little signal degradation. Since the cable does not contain any power conductors, it must
not be used for applications where connected equipment requires power. Slaving ACS racks is a signal-
only operation, thereby permitting the use of this cable. This cable uses the same Amp CPC connectors
as those on Series 200 lamp cables.
There is a practical limit to the number of cables that can be combined before minor signal degradation
occurs.
No more than four cables should be strung together to maintain signal integrity. This limits the
number of connections (major sources of noise) to five (three between cables and two at each
connection to ACS racks).
The cables are color-coded at each end to denote length: white (6 feet), red (12 feet), yellow (20 feet),
orange (50 feet), blue (100 feet), violet (150 feet), brown (185 feet), green (200 feet), and gray (250 feet).
Maximum recommended length is 500 feet.
Note: In order to use this cable properly, the associated ACS rack must have been upgraded with the Universal
Repeater Board.
Series 200 Super Lamp Run Cable
Due to data signal degradation, standard Series 200 lamp cables should not be connected for lengths
greater than 100 feet. The super lamp run cable assembly can be run up to 500 feet and is
recommended even for short runs of Virtuoso comm. This cable contains AC and data conductors
carried on three conductor, two pair composite runs. Data are carried on two individually shielded pairs
with a common drain wire. The conductor to shield capacitance of the twisted pair data conductors is
very low, allowing the cable to be run for long distances with little signal degradation. This cable uses
the same CPC connectors as those on Series 200 lamp runs.
There is a practical limit to the number of cables that can be combined before minor signal degradation
occurs.
No more than four cables should be strung together to maintain signal integrity. This limits the
number of connections (major sources of noise) to five (three between cables and two at each end of
string at equipment connection).
The cables are color-coded at each end to denote length: blue (100 feet), violet (150 feet), brown (185
feet), green (200 feet), and gray (250 feet).
Note: In order to use this cable properly, the associated ACS rack must have been upgraded with the Universal
Repeater Board.
