JLCooper Electronics eBOX

The eBOX is a general purpose interface box that converts 4 serial communication ports and 24 GPI (General Purpose Interface) inputs and outputs to 100/10baseT Ethernet. The serial ports can be configured as EIA/TIA RS-232E (CCITT V.28) or as EIA/TIA RS-422A ports. This can be performed easily in the field. Additionally, the port direction can be configured as DTE or DCE on each port independently. The eBOX communicates over standard TCP/IP which allows is be used with any host computer running any operating system that uses TCP/IP protocol. The eBOX can also be connected to other eBOXes to allow longer runs than traditional serial and GPI cables. Since the eBOX uses TCP/IP, traffic can be routed over internal LANs, wireless LANs, MANs, WANs and even over the public Internet. Typically, the eBOX functions as a server, passively waiting for client devices to connect to it. The device can be a computer or another eBOX configured as a client. When the eBOX is configured as a client, it will actively attempt to connect to the server eBOX. Once this is accomplished, the either eBOX will pass data received in the serial or GPI ports to the remote eBOX. If there is no data received in the eBOX, the eBOX will not send any TCP packets.
