  • Close the chassis and reconnect power. Turn on the computer and wait for the system to boot.
  • Install drivers using the provided driver package or the manufacturer’s online repository. Install will typically guide you through detecting the new PCI card and configuring the COM ports.
  • Connect your devices to the external RS422/RS485 ports. Ensure proper wiring and polarity for your networks, keeping in mind the need for proper termination and biasing on longer runs.
  • Configure OS settings as needed. In your operating system’s device manager or serial console configuration, assign the appropriate COM port numbers, baud rates, and flow control parameters to match your application requirements.
  • Test the setup with a loopback test or a simple data transfer utility to verify stability and communications across both ports before deploying in production.

Frequently asked questions

  • What is RS422/RS485, and why would I choose this Brainboxes card? RS422 and RS485 are balanced serial communication standards designed for long-distance runs and multi-point networks. The Brainboxes card offers two opto-isolated ports, which protects equipment from noise and faults, making it ideal for industrial automation, data acquisition, and instrument control where reliability is critical.
  • What does opto isolation mean for my system? Opto isolation uses optical coupling to electrically isolate the host PC from the serial network. This reduces the risk of ground loops, electrical transients, and potential damage to the computer, while preserving data integrity across challenging environments.
  • What does 921,600 baud support imply for my application? A higher baud rate enables faster data transfer between the PC and serial devices. Up to 921,600 baud is well-suited for high-speed telemetry, real-time monitoring, and rapid command/control tasks on RS422/485 networks.
  • What is the benefit of 128-byte TX/RX FIFOs? Deep FIFO buffers help absorb bursts of data, reduce overflow, and minimize CPU interrupts, resulting in smoother performance even when multiple devices transmit simultaneously or when the host is under heavy load.
  • Are drivers included, and what platforms are supported? The card ships with drivers to facilitate installation. While specific OS support isn’t listed here, the inclusion of drivers generally indicates compatibility with common operating systems used in PC environments, such as Windows and Linux, enabling easier integration into a wide range of setups.

Sturdy ball, holding up well.
Color: Purple
I have a ball obsessed Shih Tzu. This has become his security blanket. He literally takes it everywhere and even sleeps with it next to him. Dexter loves any ball. All shapes and sizes. He will play fetch all day long if you let him. He doesn't know when to quit. It can be 100 degrees out with 80% humidity and he'll fetch all day long. This is a larger ball, I think just over 3 inches. It is entirely too big for a Shih Tzu, but it is perfect for Dexter. He came to us with a ball similar to this that he has since lost. He carries it in his mouth by placing his incisors in the indentations and lets it hang out the side of his mouth. Quite comical actually, but it works for him. We have bought him balls more for his size, but they're too small and he gets them lost under cabinets, furniture or any nook and cranny the ball will fit. And being obsessive, he will bark and carry on because he can't get to the ball until you come and rescue it. Difficult on our old knees. So he ends up getting the smaller balls taken away from him. The other night he was laying and chewing on this ball. It sounded like he was shredding this ball to pieces. I was afraid he would choke or swallow the rubber pieces, so I took it away from him. There wasn't anything wrong with the ball. It looked brand new. No chew or bite marks that I could see. I was impressed. It does have a squeaker, but I can barely get it to squeak and I have strong hands. A larger dog with a stronger bite force could probably easily make it squeak. It claims to have a beef scent to the toy, and maybe that is why he likes the ball so much. But I sniffed it and couldn't smell anything, which is fine by me, it won't have an obnoxious smell to where I don't want it around me.

Dogs love balls
Color: Orange
Most dogs love to play with balls. This is a ball. It squeaks and can handle a lot of strong chewing. Quite durable and a good size for medium and up sized dogs. (Honestly even smaller dogs would have fun with this).

Heavy duty for sure
Color: Purple
Heavy duty toy. This ball has some weight to it! I have a smaller laber doodle that thinks she's a German Shepard so no toy is too big or heavy for her. She's been chewing on this for months but you'd never know it. The squeaker is even hard for me to activate with my hands. She hits it in the right spot every now and again and gets excited about it. Great if your not crazy about hearing a squeaker squeaking non stop!

All dog sizes can enjoy this ball!
Color: Orange
This is a terrific dog ball! Our Pittie can't tear it apart on day 2 which is unusual! Also, its big enough that he can't swallow it but not so huge that our mini Doodle can't enjoy it too! We have more than one of these to keep our pups busy!
