gBOX is a general purpose interface that converts up to 48 GPI (General Purpose Interface) inputs and outputs to 100/10baseT Ethernet, USB or a serial interface. Up to 8 gBOXes may be slaved to a master gBOX to convert up to a total of 432 GPI inputs and outputs. When the gBOX is outfitted with an Ethernet Interface (#920394) the unit functions as either a server or client. gBOX provides a portal for controlling devices across your facility or across the world. It's a simple way of remotely sending a large number of GPI contacts from one place to another over IP or an economical and professional GPI interface for computer-based applications like automations and control systems. It's ideal for LAN, WAN and Internet control with switchers, computer based systems, cameras, monitors, projectors and other devices. It's the perfect solution for broadcast television, streaming media networks, multi-room editing facilities, news production or in any audio/video/multimedia studio where you need to transfer a large number of GPI contacts over long distances or via the Internet. An ethernet equipped gBOX communicates over TCP/IP which allows it be used with any host computer running any operating system that uses TCP/IP protocol. gBOX can also be connected to other gBOXes to allow longer runs than traditional GPI cables. When configured as a server, it passively waits for client devices to connect to it. The device can be a computer or another gBOX configured as a client.
