OPN (Open Pyro Network)
An OPN card can be purchased separately and installed onto any CM or FM expanding the
abilities of both modules! The CM can receive an ethernet or DMX module allowing the CM to
send and receive signals via DMX and ethernet. The FM can receive DMX, Ethernet, and 32 pin
expansion cards, allowing DMX and ethernet communication through the FM as well as the
ability for 32 additional firing pins to be added to the FM. The OPN-32 card has an industry
standard Centronics-36 D-style connector that comes out the front side of the module and
attaches to a standard 32 shot slat.
