NOTE:  NIKON OR CANON:

Please go to their own page because of the number of models and popularity. If you do not see your brand here, we have access to over one hundred other models. Email me for the correct fit.   You need a cable to go from the battery pack to your battery compartment of your particular flash unit. The cables are all different depending on the battery layout of the flash itself. 

The module fits the battery compartment.  Most common layouts are either square, trapezoidal or "drunk rectangle" and the "inline".  At the other end of the Quantum cables you will see an RCA jack.  We do not like RCA Jacks because they have problems. We upgrade them free.  
I repeat, here are the latest Cable Charts - For Nikon go to my Nikon Page - For Canon go to my Canon Page, others are here,  again hundreds more available. Call me.

This section is devoted to enhancing  your understanding of why I do things a certain way. It contains warnings and upgrades, manufacturer changes and odd things we have encountered. Don't even order a box till you understand the ramifications. The BLACK BOX part is easy but there must be a connection between the box and the flash. This is where some folks get confused.  I will gladly call you and discuss it with you if it is not clear. They tell me I'm the only one in the industry to do this. 

THE OTHER GUY:
Makes cables we use. Specifically the Quantum cables that start with an "M". Occasionally we use some from the K series (aka Bantam Series Cables)

They are easily available from from the very reliable ABC's of mail order. Adorama, B&H, Calumet or any good pro quality camera store, or sometimes may be found used on eBay.  

TO PORT OR NOT TO PORT:
My packs come standard with two identical usable ports, both called DIN ports or plugs.
  •  They were selected for their higher reliability. 
  •  The RCA ends that come on the Quantum cables are obsolete. I detest them. (90% of the repairs I have worked on the past forty years are attributed to the RCA or correctly named "AUDIO JACKS") They were not made for power they were made for signal. NOT for power. They go back to the days of the record business.  That was before the 8-Track. 
  •  The second port on the black box allows two flashes to be used at the same time if they are of equal value in output and performance.  It is called a matching DIN. The DIN is internal, stronger, more reliable, and more secure. It's wires (both positive and negative) are internal and the only thing the outside does is to connect stronger through a threaded collar that does not stress the cable itself or the relief strain.  
  •  For the best performance and bang for your buck, we use male and female DIN plugs from Taiwan, or Japan. Not the pot-metal cheapies from the China mainland. DIN is an abbreviation for Deutsches Institut für Normung, or German Institute for Standardization, which is a German manufacturing industry standards group. DIN connectors are round, with pins arranged in a circular pattern.
  •  This type of connector in a sub-min version looks like the kind on your PC keyboards, but we use a much larger heavier type with and external collared lock. Do not confuse these with mini-DIN's. Ours is a very robust locking plug assuring good contact, low failure rate and longevity. We have never had one fail, burn up or replace.  
  •  If you already have a QUANTUM "M" series cable, with the collet that tightens, send me your cable and I will convert it (remove the end and upgrade it to the heavier DIN plug) for FREE with an order for the Black Box or Tuxedo. In fact with the 2009, we do two free.  The first time you get a two free-be. After that they are fifteen dollars for additional cables and that includes fast shipping, the cost of the part and the labor.
