I have been asked to retrofit a TRS snake with an ELCO connector for an old Soundcraft 2400 board. The schematics I received from soundcraft show the pin configuration. It says, "View from solder pin side of free connector". Does this mean that it shows the view from the side I insert the connectors, or the side the connectors snap into their counterparts? (I am connecting a female free connector to the snake). Also, the ELCO connection is for a TRS insert snake (Meaning each cable is a send AND receive (I believe)). Is there a way to alter this so that I can make separate send and receive cables? I am in a tight situation, so any help would be GREATLY appreciated!!!
