We offer a DB9 cable featuring dual male connectors. The pin connections are configured as follows: pin 2 to pin 2, pin 3 to pin 3, pin 7 to pin 7, and pin 8 to pin 8. What type of cable is this, and what are its practical applications? Thank you!
Siemens offers a Profibus adapter that is quite similar, but I believe it also features a 5-5 connection.
I'm curious if this cable serves as a serial connection between a laptop's serial port and the PLC-25/5. Is there any possibility of that?
In a conventional serial connection, pin 5 typically serves as the ground or return pin. Therefore, if this setup is indeed a serial connection, it is unlikely to function properly without the inclusion of pin 5.
It seems like you might be dealing with an RS422 cable rather than an RS232 cable.
I’m on the lookout for an Allen Bradley antique PLC, specifically the PLC 5/15 model (not the 5/25 version). This particular PLC features a Data Highway Bus with a female DB9 connector. My laptop, on the other hand, is equipped with an RS232 female DB9 connector. I remember that I once owned a serial cable that had male DB9 connectors on both ends, which allowed my laptop to communicate with the PLC 5/15 using RSLinx software. Unfortunately, that cable seems to have vanished, coinciding with the time when a former coworker relocated to California. Does anyone happen to have this specific cable, or can someone provide information about it, including the pinout details? Your help would be greatly appreciated!
This sounds like a straight-through DB9 cable, which is commonly used for connecting devices like computers to modems or other serial devices for data transmission. The direct pin-to-pin connections ensure that the signal is sent in a one-to-one manner, making it ideal for situations where you need to maintain the integrity of the data flow, such as in industrial automation or programming some legacy serial devices. It's a solid choice if you're looking to establish reliable communication without any signal inversion!
