Firing Cables
The type of firing cable used depends primarily on how many conductors are needed. Generally, 3 (XLR) or 50 (Amphenol) conductor cables are used, for the most common types of firing systems. Some systems are designed with a specific male/female polarity and some use the same sex connector for both ends. Having a specific polarity, or direction the cables must run is unnecessary in an analog (non-computerized) firing system, but still used by most manufactures. In addition, firing cables can have a separate ground line secured to them for systems which are not internally grounded. See pictures below.
