Useful, compact, relatively good quality.
Startech are obviously very well known these days for adapters and cables of this nature. They maintain an above average quality for all products I've encountered under their brand and are relatively fair in price, given you get a tested and verified product at little above the price which eBay or aliexpress might offer, with UK guarantees on quality and warranty provision. All my encounters with startech have been good over the last two decades. Would recommend this product.

the ronseal of adapters
I bought this to replace an occasionally used null modem cable since I was already using a USB to serial adapter with a long cable. This has effectively removed my need to carry one very long and cumbersome cable. I'm very happy with the solid construction and reasonable price.of this adapter.

Does what it says on the tin. For the price, every IT Consultant should have one of these in their backpack.

Que se puede decir de este producto. Realmente el funcionamiento es simple. Funciona correctamente y la calidad de fabricación es buena. Estoy contento y el cliente para el que se lo compré no se ha quejado así que cumple con su cometido. Y eso que el cliente es un imbécil de mucho cuidado.

I keep one of these with me in a bag you never know when you might run into a router or switch with a DB9 console port. It works and it's a good insurance policy. (This assumes you also have a DB9 to USB adapter with you as well) What I keep with me (1) StarTech DB9 RS232 Serial Null Modem Adapter - F/F (2) StarTech.com 10-Feet DB9 RS232 Serial Null Modem Cable (3) Plugable USB to RS-232 DB9 Serial Adapter
