IP65 connectors
The VC-Feeder™ uses custom IP65-rated connectors. To ensure that they
are correctly sealed and avoid damage, connect them as follows:
1. Line up the raised lug and corresponding groove on the connectors.
The connector pins and holes should now also be lined up.
2. Push the connectors together firmly but without excessive force. If
force seems necessary, separate the connectors and check that they
are correctly lined up, then try again.
3. When the connectors are correctly engaged, screw the locking ring on
the male connector onto the thread on the female connector until fully
tight.
Input connections
The VC-Feeder™ input (IN) is a 180 mm (7 in.) cable tail with a 6-pin male
IP65 connector that accepts 48 VDC power and data.
To connect to other currently available power and data sources, you must
first connect a Martin™ hybrid (power & data) input adapter cable, (P/N
11840165) to the VC-Feeder™ input (IN) connector. See Figure 4. The
0.25 m (0.8 ft.) hybrid input adapter cable has a:
• 4-pin male XLR connector that accepts DC power and data, and a
• 6-pin female IP65 connector that supplies power and data to the VC-
Feeder™.
Connect the 6-pin IP65 male input connector on the VC-Feeder™ to the
input adapter cable’s 6-pin IP65 female connector following the
instructions under ”IP65 connectors” above.
IP65 Input extension cables
If the VC-Feeder™ is not close to the power and data source, you will
need to extend the input cable. To do this, insert a Martin™ hybrid power +
data extension cable with IP65 connectors (see ”Power + data IP65

Figure 4 and the VC-Feeder™. Do not exceed the maximum lengths for
cable runs specified in display device user manuals.
P3 or DMX input connections
The VC-Feeder™ input connections depend on whether you are installing
a P3™ video display system or a DMX/RDM-controlled display system:
P3™ video system
In a Martin P3™ video display system, the VC-Feeder™ accepts
combined 48 VDC power input and P3 data input from a suitable Martin
P3™ power supply + data relay device such as the Martin P3 PowerPort
1500™.
To connect the VC-Feeder™ to power and P3 data:
1. Check that the system is isolated from AC mains power.
2. Connect the VC-Feeder™ input adapter cable to a 4-pin female XLR
48 VDC power + P3 data output on a suitable Martin P3™ power
supply + data relay device. If this cable is too short, insert an IP65
extension cable (see ”IP65 Input extension cables” on page 12).
DMX-controlled system
In a DMX-controlled system, the VC-Feeder™ accepts 48 VDC power
from an external power supply unit (PSU) and DMX/RDM data from a
DMX/RDM controller using a Martin™ hybrid DMX lead-in cable (P/N
11840174).
See Figure 5. The 0.25 m (0.8 ft.) Martin™ hybrid DMX lead-in cable has:
• a 5-pin male XLR connector that accepts data output from a DMX/RDM
controller,
• two wire tails that accept 48 VDC from an external power supply unit,
and
• a 6-pin female IP65 connector that must be connected to the VC-
Feeder™ input connector.

14 Martin Professional™ VC-Feeder™ user manual
To connect the VC-Feeder™ to power and DMX data input:
1. Check that the installation is isolated from AC mains power.
2. Connect the VC-Feeder™ hybrid lead-in cable’s IP65 connector to the
VC-Feeder™ input (IN) connector, inserting an IP65 extension cable
(see ”IP65 Input extension cables” on page 12) between the lead-in
cable and the VC-Feeder™ IN connector if necessary.
3. Connect the VC-Feeder™ hybrid lead-in cable’s 5-pin male XLR
connector to the DMX data output of a suitable DMX/RDM controller.
4. Connect the VC-Feeder™ hybrid lead-in cable’s two wire tails to an
external 48 VDC PSU such as the Mean Well SP-480 48. Connect the
white wire to +ve and the black wire to -ve DC outputs. Note the
maximum current rating of the PSU output and make sure that the total
current draw of all the devices connected to the output will not exceed
the maximum current rating or 7.5 A, whichever is lower.
DMX termination
DMX termination is integrated in the VC-Feeder™. No external DMX
termination is required.
Throughput connections
The VC-Feeder™ throughput (THRU) is an integral 180 mm (7 in.) cable
tail with a 6-pin female IP65 connector that can relay power and data to
other VC-Feeder™ devices in a chain.
See example in Figure 3. To create a chain of VC-Feeder™ devices,
connect one VC-Feeder’s THRU connector to the next VC-Feeder’s IN
connector.
You can connect up to twenty (20) VC-Feeders in one linked chain, but as
soon as you reach the maximum permitted current draw for a chain (7.5 A

or the PSU output’s maximum current rating if you are using an external
PSU) you must create a new chain.
If you want to install VC-Feeders further apart than their THRU and IN
connector cable tails allow, insert a Martin™ IP65 extension cable (see
”Power + data IP65 extension cables” on page 24) to extend the link
between VC-Feeders. Do not exceed the maximum cable lengths
specified in display device user manuals.
Throughput to other device types
It is possible to draw off 48 VDC power and data at the end of a VC-
Feeder™ chain for connection to other types of Martin™ device by
connecting a Martin™ hybrid (power & data) output adapter cable, (P/N
11840166) to the VC-Feeder™ THRU connector. The 0.25 m (0.8 ft.)
hybrid output adapter cable has a:
• 6-pin male IP65 connector that accepts 48 VDC power and data from
the VC-Feeder™ throughput, and a
• 4-pin female XLR connector that supplies power and data to other types
of display device.
Warning! If you draw off power and data at the end of a chain, do not
exceed the maximum permitted current for a chain as described in
“Protection from electric shock” on page 5.
Output connections
The VC-Feeder™ output (OUT) is a 180 mm (7 in.) cable tail with an 8-pin
female IP65 connector that supplies 15 VDC power and data to Martin™
LED-based display devices.
The method for connecting the power + data output from the VC-Feeder™
is the same for P3 video and DMX/RDM-controlled systems:
1. Check that the installation is isolated from power.
2. Connect the display device or chain of display devices to the VC-
Feeder™ OUT connector:
• Follow the instructions under ”IP65 connectors” on page 12.
• If you are connecting devices to a VC-Feeder that is part of a chain
(i.e. two or more VC-Feeders are linked using the THRU connector),
do not connect devices that will draw more than a combined total of
7.5 A to the OUT connectors in the chain.
• If you are connecting devices to one single VC-Feeder, you can
connect devices that will draw up to the maximum limit of 7.5 A to
that VC-Feeder’s OUT connector, but do not connect anything to
that VC-Feeder’s THRU connector.

16 Martin Professional™ VC-Feeder™ user manual
Setup
The VC-Feeder™ automatically detects the LED display devices that are
connected to it and the type of data signal (P3 or DMX/RDM) that is sent
to it.
Setting up for P3 video display
When a Martin P3™ controller is connected to the data link and the
installation is powered on, you can set up all the devices on the link for
data display using the P3 controller. See the P3 controller user manual for
details.
Setting up for DMX control
You can set up and control a VC-Feeder™ installation over the data link
using an RDM-compatible DMX controller such as the Martin M1™
console or M-PC™ Windows application.
If individual DMX control of strings or groups of devices in the VC system
is required, each VC-Feeder™ must be set up to receive instructions from
the DMX controller on a DMX channel or group of DMX channels in the
512 channels available in a DMX universe.
The DMX address, also known as the control address or start channel, is
the first of these channels. Each group of devices uses this channel and
the channels immediately above it to receive instructions.
The VC-Feeder™ uses the number of DMX channels required by the
devices connected to it. For example, if a VC-Feeder™ has its DMX
address is set to 1 and you connect a string of 100 VC-Dots display
devices (each using three DMX channels for RGB control) to the VC-
Feeder™, it will use channels 1 - 300. Channel 301 will be available for
use as the DMX address for the next VC-Feeder™.
If two or more VC-Feeder™ devices are set up with the same DMX
address, they will receive the same instructions and behave identically.
Setting up identical devices with the same address is an easy way to
achieve synchronized action and can also be used as a troubleshooting
tool.
www.audiovias.com

Setup 17
Setting up via RDM using Martin M-PC™
DMX Addressing
Using an RDM-compliant DMX controller, you can communicate with the
VC-Feeder™ devices on the data link via RDM. You can:
• Retrieve data
• Set the DMX addresses of the VC-Feeder™ devices on the link
• Apply various setup options depending on the display products
connected to the VC-Feeder™ (see the product user manuals).
To use Martin M-PC, connect a PC running this application to the data link
using the Martin USB Duo™ USB/DMX interface box.
See Figure 6. Opening the RDM View window in M-PC and clicking on
the Scan button (arrowed bottom left) gives a list of the RDM-compliant
devices on the data link (in this example, one string each of Martin VC-
Dot™ 1, VC-Dot™ 4 and VC-Dot™ 9 RGB video display modules are
present on the link, and all three strings are set to DMX address 1).
To set DMX addresses using M-PC, click in the Address box for each VC-
Feeder™, enter the desired DMX address, then press the Enter key to
store the DMX address for that string or unit.

Operation
The VC-Feeder™ automatically detects whether it is receiving P3 or
DMX/RDM data and uses the commands it receives to drive the LED
display devices that are connected to it.
Ambient temperatures
The VC-Feeder™ can be operated at ambient temperatures from -20° C
(-4° F) to 55° C (131° F). Do not operate it outside this temperature range.
P3 video display
You can display video on the LED-based devices connected to each VC-
Feeder™ by sending a video data signal from a Martin P3™ system
controller over the data link.
Displaying video on a VC installation is managed from the P3 system
controller. See the P3 controller manual for details.
DMX control
If the display devices connected to the VC-Feeder™ have been set up
with individual DMX addresses, each device can be controlled as an
individual pixel using DMX.
If a string of display devices connected to the VC-Feeder™ has been set
up so that the devices share the same DMX address, the devices will
behave identically and the string can be controlled as one unit (one long
pixel) using DMX.

to send test patterns to all connected devices and reset the device
together with the display devices connected to it.
The test patterns that are stored in internal memory let you check that the
video display products in an installation are correctly connected without
