2. Introduction & Basic Usage
A. General Description
ProtonPackisabackpack-worncameraaccessoriesplatform.Itprovidesmountingoptionsfor:
• Batteries (gold mount or v-mount)
• MDR
• Wireless HD Transmitter
• Timecode generator
• Cinetape readout
• Focus Monitor
Handheld shooting and cramped spaces often require cameras to be made as small as possible.
DPs often request that the camera be completely stripped-down. Proton Pack provides a solution to
accomplishthesebuildswithoutcompromisetonormalwork-ow.
Velcro surfaces and cheeseplates allow attachment for all of your professional accessories.
Camera builds can now be reduced to only body, lens, & focus motor. Proton Pack’s power system is
ready for 14v or 28v cameras and provides regulated 13v breakout power (2x p-tap & 2x Lemos) for all
peripherals.
IdealforworkingwithArriAlexaMini,RedDSMC2,andlmcameras,ProtonPackisacomplete
system providing all custom umbilical cables and accessories you will need for any build.
B. Basic Usage
• Begin by choosing the appropriate power pigtail for your camera system. For any camera that can
accept ±12v DC power the “14v” pigtails are always preferred as they maintain hot-swapability when
changing batteries. Pick the “14v” 4pin XLR or 3pin XLR pigtail based on the power cable included with
your camera*. For ±24vcamerasystems(35mmlm,AlexaLF/65,etc.)pickthe“28v”3pinXLRpigtail
• Install the power pigtail into the 6pin 2B Lemo “Camera Power” port on the Proton Pack main chassis.
• Strip down the camera body to the bare minimum of rigging (cage, baseplate, etc.). Leave only
essential accessories for shooting and operating (lens, monitor, focus motor, hand grips, etc.)
• Using Velcro or other brackets, mount all required peripherals
(Teradek/MDR/Cinetape/etc.) onto the Proton Pack frame
(Seeg.1foratypicalarrangement).
• Run power for all peripherals (using their standard power
cables) from the two 13v p-tap or two 13v 2pin Lemo ports
on the Proton Pack.
• Connect your camera power cable to the Proton Pack
Pigtail you installed earlier.
• Using the included long cables in your kit now make all
other connections between camera and Proton Pack. We
recommend starting at the camera side and taking up any
additional slack in the cables at the Proton Pack frame.
• Once the umbilical is fully assembled, we suggest attaching
the strain relief cable from umbilical to camera cage & also
securing the umbilical to the Proton Pack using the strain
relief loops at the bottom left or right corners.
• Attach batteries to both battery plates.
• Power on the camera and all accessories.
• With the Proton Pack worn by camera operator, AC or grip,
now begin shooting.
• Change batteries as needed when indicated by the yellow
“low voltage” LED.

3. Power System & Power Modes
A. Power System Introduction
Proton Pack can provide power for both 14v and 28v camera systems from the “camera power”
port on the main chassis. This mode is automatically selected when installing either a 14v or 28v power
pigtail cable. 14v mode has hot swap. In 28v mode there is NOT full hot swap when changing batteries.
Camera power is a direct pass-through from your battery plates. Voltage and ampacity will be
reectiveofthebatteriesinuse.
The system also has four built-in ports for
powering peripherals/accessories. There are
two Anton Bauer type p-tap ports and two
standard 2pin Lemo ports. All four outputs are
regulated at 13v DC and will provide that
voltage regardless of 14v or 24v voltage mode.
Hotswappingcanbeconguredina
“Priority”or“Parallel”protocolbyippingthe
small toggle switch located underneath “battery
plate2”(seeg.2).
g.2
B. 14v “Priority” Power Mode
This is the standard operating mode for your Proton Pack and it will ship to you with this mode pre-
selected. Choose this mode by installing one of the “14v” power pigtail cables and leaving the internal
toggle switch set to “A-->B” (right position).
In this mode your Proton Pack will always prioritize “battery plate 1” (left-hand) when there is a
healthy battery installed on that plate. “Battery plate 2” will constantly be kept in reserve as a backup if
the primary battery should die or be removed.
Only the LED on the battery plate actively supplying power will be illuminated in this mode.
C. 14v “Parallel” Power Mode
If battery plate prioritization is notdesired,yourProtonPackcanbereconguredtodrawfromboth
battery plates simultaneously. Choose this mode by installing one of the “14v” power pigtail cables and
changingtheinternaltoggleswitchto“A&B”(leftposition)(seeg.2).
In this mode the power system will actively favor whichever source has the higher voltage thus
draining both batteries in a relatively symmetrical pattern. Hot swap will function as normal whichever
battery is removed during a swap. It is recommended that batteries of approx. equal charge are used.
Both LEDs on the Proton Pack will be illuminated in this mode.
D. 28v Power Mode
Usethismodeforlmcamerasandlargercamerasystemsrequiring>24v.Choosethismodeby
installing the “28v” power pigtail (internal toggle switch has no effect in this mode). To achieve > 24v
bothbatteriesareconguredinseriessohotswapisNOTavailableinthismode.Make sure to safely
power down digital cameras before swapping batteries in 28v mode.
Both LEDs on the Proton Pack will be illuminated in this mode.

E. LED Indicators
There are two multi-color LEDs on the Proton Pack chassis, one for each battery input.
• GREEN = Good voltage ( >13v / >26v)
• YELLOW = Low voltage ( < 13v / < 26v)
• RED = Dead battery
• OFF = Battery not active or no battery present
• BLUE FLASH = Over current warning ( >10A camera, >5A accessories)
• RED FAST FLASH = Electrical system fault
• RED SLOW FLASH = System overheat ( >185 deg. F)

F. Circuit Breakers
The camera output and the accessory output each have a resettable aviation-style pop breaker
which can be accessed from either side of the Pack. If there is a short circuit or other electrical fault
at the camera or on any of the accessories these circuit breakers will trip and protect the Proton Pack
from damage.
In addition, these breakers can be manually pulled so as to intentionally cut power to the camera
or on-board peripherals while leaving the batteries installed. This my be useful, for example, on a lunch
break when it is desirable to power off all accessories, but it is inconvenient to remove the batteries.
• CAMERA POP BREAKER: 10A slow-blow (Klixon 7277-2-10)
• ACCESSORY POP BREAKER: 5A slow-blow (Klixon 7277-2-5)
4. Battery Plates
A. Standard Plates
Proton Pack comes standard with the customer’s choice of pre-installed GOLD MOUNT or V-MOUNT
battery plates. These are for use with 14v-standard battery systems only.
It is possible to purchase additional plate sets from backpackrig.com and these can be changed in
theeldbytheuserifnecessary.
B. Swapping Battery Plates

C. Use of 26v Batteries (advanced users only!)
Proton Pack is compatible with high voltage 26v-standard battery systems now available
from Anton Bauer (“Dionic 26V”) and Bebob (“Cine 12/24”). This will require swapping over to a
26v-standardbatteryplate,either:AntonBauer“GoldMountPlus,”orBebob“B-Mount.”Theseplates
will be available for purchase from backpackrig.com. Use of these batteries will allow hot-swap for 26v
cameras. This is for advanced use cases only, read all following steps before starting this conversion.
STEP1: SwapbatteryplatestoGoldMountPlusorB-Mountfollowingstepsinsection4(b).

STEP2: ***Important-Beforesecuringtheright-handbattery(plate2),changethetoggleswitch
located underneath that plate to the “24V” (right-hand) position. Finish securing both battery plates.
STEP3: Installthe yellow “14v” 3pin XLR power pigtail cable. Use only this specic pigtail cable in
this mode! Your Proton Pack will now provide 26v DC power & maintain hot swap capability during
battery changes. P-tap and 2pin Lemo ports will still deliver 13v accessory power.
***EXTREMELY IMPORTANT: DO NOT Use the red “28v” power pigtail cable when work-
ing in this mode! It will send upwards of sixty volts into the circuitry and completely
fry your Proton Pack electronics. Despite the nomenclature miss-match, only use the
yellow “14v” 3pin XLR pigtail with native 26v batteries!
5. Peripheral Mounting
A. Using the Velcro Pads
ThereisalargecarbonberplateoneithersideoftheProtonPackframecoveredinlow-prole,
industrial-strength Velcro-brand loop-side fabric. Your accessory or peripheral device can be positioned
anywhere you need on these pads by attaching a small piece of standard hook-side self-adhesive
Velcro.
We recommend placing your video transmitter high up on the pack for better signal transmission.
MDR units work best lower down, closer to the battery plates to facilitate the most direct path for focus/
irismotorcables.Timecodeand/orrangenderreadoutboxescanbepositionedwhereverthereis

B. Proton Pack Hard Mounts
Proton Pack has a variety of built-in hard mounting points for attaching accessories which you may
prefer to bolt-on, or position with an Israeli arm or other bracket. Use these attachment points as you
would with any standard camera cage.

Pass-ThroughChannels:
By inserting a 3/8 inch bolt from the rear/interior of the cheese-plate spine it is
possible to attach a quick release or camera body directly to the surface of the
spineexactlyasyouwouldwithanynormaltripodquickreleaseplate(seeg.8).
To access the back of the spine often it will be possible to simply reach your
hand in the gap behind the backpack pad from the side of the frame. If more
room is required, detach the bottom portion of the backpack pad (see section
7(A), pg. 17) and fold it up out of your way.
3/8-16ArriAnti-RotationHolePatterns:
Attach any 3/8 inch accessory featuring Arri-standard anti-rotation pins to the
frontfaceofthespine(seeg.9).
Additionally, it is possible to insert the two included steel pins from the interior
of the plate and thread them into the rear of the M3 anti-twist holes using a 1.5mm
Allen wrench. Now female-threaded accessories with anti-rotation holes can be
hardmountedtothefaceoftheplatewithastandard3/8-16screw(seeg.10).
