8 VC-Dots™ user manual
Connection to a 48 VDC PSU (DMX-controlled system only)
One or more 48 VDC external PSUs (power supply units) are required to supply DC power to VC-Feeders
and then to VC-Dots in a DMX-controlled VC-Dots installation. The maximum number of VC-Dots that you
can safely connect to an external PSU in a DMX-controlled system installation varies depending on the
power rating of the PSU and the type of VC-Dot.
Check the maximum power rating of each PSU. The total power consumption of the VC-Dots that you
supply with power via a PSU must not exceed the PSU’s maximum power rating. To determine the total
power consumption of a chain of VC-Dots, add together the power consumption of all the individual Dots
using the figures given below (the figures make allowance for cable resistance, etc.):
• Allow 1.2 W per VC-Dot 1
• Allow 1.9 W per VC-Dot 4
• Allow 3.4 W per VC-Dot 9
Each time the total power consumption of the VC-Dots that you connect to a PSU reaches the PSU’s
maximum power rating, use a new PSU connected to a new VC-Feeder or chain of VC-Feeders.
Note that you may have to remove VC-Dots from the strings supplied by Martin™ by cutting the ribbon cable
to make sure that strings do not exceed the PSU’s maximum power rating. The lengths of VC-Dot string that
you remove can be re-used (see “Modifying Dot pitch and splicing VC-Dot strings” on page 10).
Hybrid cable link
The maximum safe length for any one hybrid (power and data) cable link from either:
• a Martin P3 PowerPort 1500™ in a P3 video display installation or
• a 48 VDC external PSU in a DMX-controlled installation.
to either:
• a single VC-Feeder that is not linked to other VC-Feeders in a chain (C
1
in Figure 2 on page 11) or
• the last VC-Feeder on a chain of VC-Feeders (total of C
1
+ C
2
+ C
2
etc. in Figure 2 on page 11)
is 50 m (164 ft.). Do not exceed this limit.
Connection to a Martin VC-Feeder™
Do not try to connect more than one string of VC-Dots to one VC-Feeder.
The maximum safe number of VC-Dots that you can safely connect in a string to one VC-Feeder depends
on three factors:
• Type of VC-Dot (VC-Dot 1, 4 or 9),
• Lead-in cable length, and
•Dot pitch
Table 2 on page 9 gives the safe limits for different combinations of these three factors. Do not exceed these
limits.
Type of VC-Dot
Larger VC-Dots consume more power, so the maximum number of Dots on a string can vary for VC-Dot 1,
VC-Dot 4 or VC-Dot 9 strings.
Lead-in cable length
The length of a VC-Dot string’s lead-in (the distance between the VC-Feeder and the first Dot) affects the
maximum number of Dots for the string.
The maximum possible lead-in cable length from the VC-Feeder to the first Dot on a string is 5000 mm
(16.4 ft.). Standard VC-Dot strings are supplied with a 2000 mm (6.6 ft.) lead-in. Martin™ can supply strings
with a 5000 mm (16.4 ft.) lead-in to special order. Please consult your Martin™ supplier for details.
Dot pitch
The Dot pitch of a VC-Dot string is the center-to-center distance between the Dots on the string.
VC-Dots are supplied in strings with the following Dot pitches as standard:
• VC-Dot 1: 100 mm (3.9 in.)
• VC-Dot 4: 200 mm (7.9 in.)
• VC-Dot 9: 400 mm (15.7 in.)
