These connectors, resembling printer ports, are used for the optional COBRA slats. The smaller port (DB25) is for the 18S slat and the larger port (CEN50) is for the 36S slat. Each slat connected will fire in parallel with any cue connected to the module directly via on-board cues or quickplugs.
What are the large "printer port" connectors on the top of my 36M/72M with onboard cues?
