WHY CHOOSE THIS PRODUCT?

• Organizations choose the ICUSB232PROC when modern USB C systems must continue supporting RS232 equipment without replacing functional legacy hardware. Its built in COM retention is particularly useful for repeat service workflows because assigned serial port values remain associated with the adapter when it is reconnected to another USB port. Compared with basic USB C to serial adapters, it combines COM retention, 921.6 Kbps operation, a 512 byte FIFO and screw lock DB9 connectivity in one cable. This makes it suitable for IT replacement programs, industrial automation, POS environments and technical maintenance where compatibility and repeatable deployment matter.
