Specification Reference
Technical specifications for Brainboxes products including electrical, environmental, and performance data.
📄️ Are the parallel ports on your serial cards ECP and EPP enabled?
No. ECP and EPP support require special hardware logic. All of the parallel ports on the Brainboxes serial cards are fully SPP enabled. They are also capable of 8 bit input and output using the standard 8 data lines.
📄️ Which power connector is used for the ES-346 & 842?
This FAQ explains which power connector is used in the following devices:
📄️ Which power connector is used for ES and BL products?
This FAQ explains which power connector is used in the following devices:
📄️ How do I choose a Serial Card for my PC?
PC cards are still a great way to add Serial connectivity to your desktop or server and Brainboxes do a large number of Serial cards which can slot in to the back of your PC. They offer a dependable direct connection between your computer and any device that uses one of the Serial standards. Because Serial has been around for decades and so many different types of device use it you will find lots of options available, from the shape of the connectors to the type of interface.
📄️ How do I find out if an unusual baud rate is supported by my Brainboxes Serial card?

📄️ How long is the response time for an ED device?
There is no mechanism that lets the host computing device know when an analogue input has changed state. Rather the host computer (PC, Tablet, Phone, Raspberry PI etc) needs to continually poll the ED-549 to get it to return the current input value from one or more of its analogue input channels.
📄️ What Baud rates will your Bluetooth products work at?
Brain Boxes products will run at the maximum Bluetooth data rate of 1 MBaud. Please see Bluetooth Baud Rates in the Bluetooth data sheet. The effective data throughput is 721kbps once encryption and authentication is taken into account. To achieve these speeds, the RS232 Adaptor (BL-510) must be attached to a fast serial port (e.g. Brain Boxes CC-302 PCI 2 Port Velocity RS232 ).
📄️ What does 450, 550, 750 UART compatibility mean, and why is there no 950 ?
Over time new models of UART have been designed, some specifications have become industry standards (such as 450, 550 and 750) others either were superseded too quickly or no definitive spec was universally accepted.
📄️ What does your basic development kit consist of?
The basic developers kit includes hardware, with a hardware transport driver for the main Windows operating systems (not currently available for USB) and Bluetooth test tools. It does not include a compiled Bluetooth software stack. It allows a user with a Bluetooth stack to connect to the hardware at the HCI layer of the CSR chip via a virtual serial port.If you buy H4 versions of the PCMCIA, CF, or RS232 products you can connect them to any standard Bluetooth stack that is able to interface at HCI level to a serial port.
📄️ What is the maximum throughput that my ES/ED device can support?
The maximum throughput that an ES/ED device can support is determined by several factors:
📄️ What is the switching speed for ED outputs when they are driving TTL or CMOS loads?
This FAQ explains the factors that can effect switching speed for the ED.
📄️ What is the temperature and humidity range for Brainboxes Bluetooth Products?
Storage Temperature 8% to 95% non-condensing
📄️ What is the temperature and Humidity range for Brainboxes Serial Products?
Storage Temperature 8% to 95% non-condensing
📄️ What is the typical Mean Time Between Failures (MTBF) for Brainboxes Products?
MTBF for our products is estimated at a minimum of 60,000 hours.
📄️ What is the watchdog timer and how do I use it?
The watchdog timer is a feature on the Brainboxes ED range that performs a specific operation after a certain period of time if something goes wrong with the system and the system does not recover on its own. The watchdog timer can time out under 1 of 2 user programmable circumstances:
