Introduction
The eBOX GPI8 is a general purpose interface box that converts 8
GPI (General Purpose Interface) inputs and outputs to 100/10baseT
Ethernet.
The eBOX GPI8 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 GPI8 can also be
connected to other eBOX GPI8es to allow longer runs than
traditional GPI cables. Since the eBOX GPI8 uses TCP/IP, traffic
can be routed over internal LANs, wireless LANs, MANs, WANs
and even over the public Internet.
Items such as IP address, remote IP address and TCP port are set
using the eBOX Configuration Utility. Settings are stored in
nonvolatile memory.
Typically, the eBOX GPI8 functions as a server, passively waiting
for client devices to connect to it. The device can be a computer or
another eBOX GPI8 configured as a client. When the eBOX GPI8
is configured as a client, it will actively attempt to connect to the
server eBOX GPI8. Once this is accomplished, the either eBOX
GPI8 will pass data received from the GPI ports to the remote
eBOX GPI8.
