VP-X Pinout and Configuration

• Pin: the actual pin number on the connector.
• Bank: The VP-X Pro has two independent systems in one box. Each system is referred to as a "bank" of circuits. This column shows which bank that specific power pin is on. See Installation manual for details on determining which device goes on which bank.
• VP-X Pin Name: Describes the function of that pin. 5A-1 for example is a 5 amp circuit and it is the first five amp circuit. 10A-3 is a 10 amp circuit and is the third 10 amp circuit.
• Power pin name: You can give each pin a name that shows on the EFIS display.
• Current draw: The actual current drawn by a device. It is recommended you measure the ACTUAL current draw of each device prior to installation in the aircraft using an ammeter (commonly available from a friend at no cost or from Radio Shack, Sears, and electronic supply stores for a reasonable one).
• Wire size: the wire size you have specified to go between the VP-X and the device being powered.
• Circuit Breaker: The maximum current allowed for that pin. You can enter any value between 1 and the limit of that pin in increments of 1A. This value is equivalent to a circuit breaker or fuse. If a load draws more than the Circuit Breaker value, that circuit will fault. If too large of a breaker value is used, then the wire may overheat or fail. If too small a value is used, then the device may fault the circuit because it draws too much current.
• Switch: The number of the switch input (switch input 1 through 10) you have specified to control this pin. Or it can be set to 'always on' or 'always off'. Each switch input is labeled 1 through 10. You can assign multiple devices to a single switch, and conversely, a switch can control multiple devices. If you set the circuit to 'always on', it will be on anytime the VP-X is powered (i.e. the master switch is on). Multiple pins can be assignedto a single switch. You don't have to use all of the switch inputs.
• Current Fault detect: The pin can be configured to detect a "current fault" or open circuit. When a circuit with this feature enabled is turned on and does not draw any current for 3 seconds, the circuit is faulted. You can use this to detect burned out lights, faulty boost pump, failed avionics fan, or inop heated pitot tube for example. The minimum detectable current is about 100ma, so this should be used on devices like lights, strobes and loads that draw at least 100ma of current.
