The BC4 is a network-enabled enclosure which houses one of our available BCX series expansion modules. The BC4 has a built-in web server for easy setup from any browser, and supports network communications via TCP or UDP sockets. It supports PoE (Power over Ethernet) and can also be powered via an available 12VDC wall adapter. The on-board temperature sensor allows you to monitor and respond to temperature changes in equipment racks, plasma displays, projectors, or anything else. When you plug one of our BCX series expansion modules into the BC4, the BC4 automatically senses which module was installed, and configures itself accordingly. That’s when the unique power of our command protocol comes into play. We’ve spent considerable time and energy ensuring that our two-way command protocol is as complete and robust as we can make it, while maintaining ease of use. Our protocol includes get/set commands for all device settings and hardware control, as well as polled and asynchronous status reporting. Download our communication protocol document to see how complete and easy to use our protocol truly is. And since the BC4 has field-upgradeable firmware, you’ll always have access to the most recent features and updates.
