Lost time in the field can be a lot more costly than the purchase price of a second cable. As much as we all wish that everything was as reliable as the CR, all adapter cables eventually fail. The connector was reduced from a pin connector to a 9-pin connector, but RS ports remained present on every computer for many years. In the old days of personal computers, one of the primary connections available was the RS serial port. The Selective Suspend option allows Windows to put your hardware to sleep, which can result in corrupt data packets.

He directs a group of talented, experienced technical support engineers. In the Property field, select Hardware Ids from the drop-down menu. We’re active on Social Media! In the old days of personal computers, one of the primary connections available was the RS serial port.
USB to RS-232 Adapter (35cm)
These IDs respectively indicate the manufacturer and the model number of the chip. The USB provided smaller connectors and more data throughput than the serial and parallel interfaces it replaced. His specialties include serial communications and advanced data logger programming.
USB to RS adapters are commodity pieces of computer equipment. USB devices have high throughput, but they use a shared data bus.
