I use to have a small LED on the panel that would illuminate when my boost pump was on. It was on the periphery of my vision and was frequently ignored. When I upgraded my system to Skyview HDX I created a digital indicator and placed it directly beside my RPM gauge. Now it’s always in my primary line of vision and is difficult to ignore. Well worth the effort.
Notes:
Contacts
Contacts may be connected to any general purpose input pin on the SV-EMS-220/221’s D37. The number of contacts in your SkyView system is only limited to the number of unused general purpose input pins on the connector.
Contacts are used for a variety of purposes, such as monitoring canopy closure. The EMS Software reads the voltage state of general purpose inputs. To configure them as contacts, use two voltage ranges in your sensor setup. Set one to 0-2V, and the other from 2-5V. SkyView will then report whether each input is open (no connection to ground, which is the 2-5V state) or closed (connection to ground, which is the 0-2V state). You must ensure that when closed, the contact connects to a ground common to the SV-EMS-220. Generally, the voltage on the general purpose inputs should not exceed 15 volts, but the inputs are protected against spikes up to 30V. Generally, it is safe to connect a general purpose input up to any 12V electrical signal (such as monitoring whether power is connected to a 12V fuel pump), but the same is not true for a 24V aircraft – connecting 24V (continuous) to a general purpose input will damage the input.
General purpose input pins are 0 to 5 volt inputs. While higher voltages are tolerated, the voltage will not read higher than 5 volts. Therefore, only use voltages between 0 and 5 volts in your sensor setup.
