Worthless RS232 Serial Cable for Industrial and Scientific Use

My analysis of this wiring and connecting product showed that it was sub-par and unfit for use in industrial and scientific settings. The cable did not function properly and caused numerous issues during communication protocols. The only positive aspect of this product was the affordable price point. Unfortunately, the low price did not make up for the wasted time and resources trying to make this cable work. Overall, I would not recommend this product to anyone in the industrial and scientific

Pros
  • Affordable price
Cons
  • Functionality issues, unfit for industrial and scientific use

Almost serviceable - modem cable

The description says: Connected as a null modem cable to a 9-pin serial port, 2-3 lines of which are crossed (only TX/RX and data lines are connected) to ground signal wires ); the standard is shielded with aluminum foil And it is true that pins 2 and 3 are optionally bridged, but it is not true that only TX and RX are grounded. All other pins are connected directly, which means that if you connect it to another DCE device, both sides will try to drive the same lines. Even if you don't have a…

Pros
  • Cables and connections
Cons
  • I vaguely remember

Almost Useful: Computer Accessories and Peripherals

Description says: Connected as a 9-pin serial zero modem connector cable, where 2-3 lines are sewn together (only TX/RX data lines and signal ground lines are connected); the standard is shielded with aluminum foil And it is true that pins 2 and 3 are optionally bridged, but it is not true that only TX and RX are grounded. All other pins are connected directly, which means that if you connect it to another DCE device, both sides will try to drive the same lines. Even if you don't have a…

Pros
  • Wires inside are 30 AWG, easy to solder and connect to pins in order of standard wire color code
Cons
  • boring packaging
