Rs-232 DB9 to DB25 cable pinouts
We make about 5 different ones and I have the pinout for about 10 more... just depends on what they are doing This is one and will work on several others https://www.plccable.com/allen-bradley-programming-cable-1784-cp10-plc-5-serial/ ... Plus, if you are using Mitsubishi PLC's, the DB25 is not RS-232. In the DB-25 end of their SC-09 cable is hidden a protocol converter to RS-422. Click to expand... They also have a backdoor for lack of better words and a RS232 ... More on plctalk.net

March 8, 2009DB25 serial cable pinout?
Hi all, After an hour of googling, I concede to ask this seemingly dumb question here; How is a typical printer cable wired? Is it as I suspect; 17 usable signal pins, and 8 pins that are clustered together to be used as GND? Or are there components hidden in the connector? More on forum.arduino.cc

OK today I was asked to run some data lines from what I think was a 'serial port hub' to CNC milling machines. Now the factory has a large number of these units and when I started looking at how the current working ones where pined out I found many differences. Some seemed to be working on...

Does RS232 play any role in modern computers?
Most industrial automation and surveying laboratories continue to use serial port technology in spite of its limitations. The re-introduction of DB-9M connector on the Tecra personal computer by Toshiba proves that these standards are here to stay for now. Despite their differences both USB and RS-232 standards support most software programs in major operating systems.

We have received email suggesting that the above pinout looks like DTR from one side is driving into DSR/DCD on the other side - not normally a healthy situation. The emails miss the point that since this is a NULL modem connection both ends are DTEs. The two peer DTE's treat DSR/DCD signals as RX (INPUT) only. The INPUT DSR/DCD on one side is created by cross connecting the OUTPUT DTR signal for the other peer. Use when connecting a DB9 (e.g. a PC) to a DB25 (e.g.

[SOLVED] Plotter cable DB9 to DB25 pinout? | All About Circuits
August 20, 2021 - The USB to serial cable is similar to this https://www.adafruit.com/product/18 I've gone through a bunch of pin configuration but I can't get the flow control working. The plotter complains about buffer overflow and says check the handshake. The program is set to use hardware flow control with DTS, DTR, CTS, RTS enabled. BTW, the plotter has Centronics for the LPT, and DB25 for the RS232.
