![]() ![]() ![]() Its a 3.3V converter built with the MAX3386E chip. One type of the “Made in China” ones, not mentioned at ist the “S30880-S5601-A802-1” its WHITE wire is data out (TX) of the DTE (PC) and conntcts to the RX of the DCE (Router) the ORANGE one is data in (RX) of the DTE (PC) and conntcts to the TX of the DCE (Router), VCC and GND are red and black. PC serial ports are usually configured as DTE.

There should be no need to modify the PCB embedded in the cable. Connective Peripherals USB Type-C to Serial Connector Cables offers hassle-free connection with a reversible USB plug and allows direct connection to. Commonly used serial cables fall into one of the two following general categories. Usually the VCC is red and the GND is black, but the other colors may vary (though blue and orange are common). If you've found a good cell phone cable to use, you merely need to determine which wires are the VCC, GND, TX, and RX connections. ![]() One known chip is a MAX323 (yes, 323, the original MAX232 is a 5V device and we need 3.3V here). If you open up the cell phone cable's serial port casing and see a MAX# chip, it's probably the cable you need. Using an existing cable is much easier than building one. 9 pin straight-through serial DB9 cable connects your computer to the device with RS232 compatible (COM port) interface. Many people already have such a cable laying around, or can buy one fairly cheap. jonathanjo Im not quite sure about Ciscos parlance - a console port on a switch is in the DCE role and connects to a DTE. ![]() Most cell phones need this same circuit to level-up for connection to a PC's serial port. Method A (reversible changes to Arduino board)Īnother great source for RS232- TTL converters is in cell phone serial cables. The outputs from this chip connect to the RX and TX pins on the microcontroller, and are generally suitable for use with other chips that operate at similar voltages. I was unable to get this to work with a Arduino nano Clone with the CH340 usb serial chip.Ī PC typically communicates with an Arduino such as the Uno via a USB cable that enters the board via a chip that does USB - serial conversion to allow use of the microcontroller's serial interface. A serial cable is a cable that can be used to transfer information between two devices using serial communication, often using the RS-232 standard. Perfect for marine or outdoor applications. This technique works since the Arduino Uno REV3 has a chip called the atmega16U2, which is a serial to USB converter, to talk to the computer we use it here to talk to the router. This IP67-rated 9-pin DB9, male to male serial cable forms a watertight seal when connected on a smooth surface. This method uses the Development board's built in USB to RS232 converter and results in 5V signals. The usage includes USB null modem, USB to IEEE 1284, USB to MPSSE, USB to RS232, USB to RS422, USB to RS485, USB to TTL Serial (1.8V,3.3V,5V), USB to UART. That said, this technique worked well for me during for lots of use (hours), with a Linksys E1000 v1 at 3.3v, and an Arduino Uno REV3. Therefore, using the following technique may cause the router, Arduino, or other things, to malfunction or break. Windows based PC with USB Port USB-Serial Driver Operating Systems.

GE MultiNet4 Serial Server & Managed Switch. RS offer a selection of high-quality serial cables from leading. Serial cable assemblies mostly use the RS-232 (Recommended Standard 232) interface specifications. The cables achieve this via serial communication protocols (data sent one bit at a time). SAS4 24Gb/s External HD 24Gb/s Cables Int. A serial cable is a computer cable used for data transfer and information between computers. ![]()
