أسئلة متكررة

What’s the difference between null modem cable and straight-through DB9 cable?

Null modem cable crosses transmit & receive pins to connect two DTE devices directly; straight cable only works for DTE-DCE matching.

Is this 3m F/F null modem cable compatible with industrial PLC programming?

Yes, standard RS232 protocol supports most PLC, serial testing instruments and old COM port equipment for data upload/download.

Does the shielding prevent signal drop in factory electrical environments?

Full aluminum foil shielding reduces electromagnetic interference, ensuring stable serial signal transmission near power equipment.
