Db9 Serial Cable Wire Colors
Red – digital serial input (RS-232Rx or RS-485 A) Orange – setpoint input or remote tare (via grounding) Yellow – digital serial output (RS-232Tx or RS-485 B) Green – primary 0-5, 1-5 or 0-10 volt DC analog output. Blue – DC power input. Purple/White – ground. DC Series double-ended 8-pin mini-DIN cables. Blue cables indicate the termination of telecommunications media and are required only at the equipment room end of the cable, not at the telecommunications outlet. Red cables are used to signify the termination of key telephone systems within an organization. Various Colored Wire Jackets in Cables.
