Serial communication has been used by computers for many years though it is not as widely used in today’s market. When most people refer to serial, they think of the DB9 cable.

It is referred to as DB9 because it carries nine pins within it. There is also DB25 in the serial family, which obviously carries 25 pins. DB9 was typically used for devices such as gamepads, mice, keyboards, or other such interface devices.

The StarTech NM9MM null modem adapter features two DB9 serial male connectors on either end to allow you to connect two female serial cables together. This is a great cost-saving way to convert a straight through cable into a null modem cable.

Null modems are usually used to connect DTE (data terminal equipment) like terminals or printers together using an RS-232 cable. Originally, the RS-232 standard was developed and used for teleprinter machines that could communicate with each other over phone lines. This was so that you wouldn’t have to use an actual modem for transferring information between the two devices.

DB9 Female to Female Mini Gender Changer - Through Signal

Joining Forces

Welcome, everyone, to FireFold’s Coupler Corner where there is no such thing as “opposites attract!” This is the number one place like-minded cables can make a solid, lasting connection in a safe and professional environment. We know it can be hard to join two cables together. Whether you need to unite them for an hour or a lifetime, selecting just the right bond can be tough. It shouldn’t be a high-pressure race against time, though. With the right coupler, mating cables end to end is easy, reliable, and quick. Here you can find a coupler for a signal so solid you might forget those cables were ever separate. All of our couplers are small enough to tuck in your pocket and take on the move, so they’re even great for temporary arrangements.

Female to Female DB9

For connecting two male DB9, Serial, or RS-232 ends together, you can’t go wrong with the DB9-FF. They are also frequently called “gender changers” or “gender benders.” This professional coupler features two DB9 female jacks. DB9 is most frequently seen as the data connection for older printers, machinery, and computers or as the network interface in modern entertainment centers and home automation. The machined pin threads provide a tight, secure slot for tightening down cable screws. When the cables are firmly seated in place, this coupler can dependably hold the connection despite any pulling, tugging, or pressure. These connections are generally used strictly for data.

These DB9 couplers can be used with any of FireFold’s 9-pin serial cables, splitters, or adapters for customized display solutions. In most cases, DB9 cables can be run fairly long distances, so feel free to extend without worries. It doesn’t matter to us how long you plan for your cables to be joined, either. You can still enjoy our picture-perfect match of low prices and high performance. With our signature lifetime warranty, you can expect this coupler to create quality connections for as long as you both shall live.
