Sunnyvale, CA | To hook up an external switch input to the DE9-M connector on the EZ-Guide Plus or EZ-Guide 500, connect pins 4 and 5 together. do NOT connect either of these pins to any external voltage, connect them only to themselves. Use a relay to isolate the pins from any other circuits. cable 52033 brings all of the other pins on the DE9-M connector to their own separate ports, the GPS NMEA, External Keypad and the Radar out and external switch input to a weather pack connector. | |
