9 Pin Serial Cable Color Code

Some devices use other rs 232 pins for flow control.

9 pin serial cable color code.

Pin 3 on standard db 9 and db 25. On second look the colors do seem to go with the pin numbers. There is no standard color scheme. Brown should be pin 1 white should be 9 and the others follow standard color code.

This pinout can make a world of difference for successful rs232 serial communications. One of the most common schemes is for the dte the pc to assert the rts signal if it is ready to send data and dce the modem to assert cts when it is able to receive data. D sub 9 connector pinout. Pinout and diagram of de9 connector db9 connector commonly used for serial ports rs 232.

You need to go from the connector pins to each wire to correctly identify the function. Shown is a 9 pin male de 9m connector plug and a 25 pin female db 25f connector socket. Rs232 serial port monitoring hardware stands out for a number of reasons including its 9 pin rs232 pinout. I am also unsure if these colors are ubiquitous or if it just a standard that is typically followed.

I m looking to splice wires from a db sub 9 pin connector out to a breadboard but i m getting different pictures for color coding which makes me confused. What s more confusing is the connect i have only has 4 wires form the cable despite having 9 pins. If your serial communication is one way then you might only use two pins. These codes apply to later model motors approximately early 80 s to present.

Indeed there is a number of possible serial connectors. Thus it is important to understand how the 9 pin rs232 cable pinout can affect the flow of serial data between devices. Wiring color codes here is a listing of common color codes for mercury and mariner us made outboard motors.
