NOTE: Although fully supported and still in production, this is a legacy product and not recommended for new designs. For new designs, the SNAP-PAC-EB1 brain is more powerful and costs less. Or, if you require PPP communication over a modem, we recommend the SNAP-PAC-R1 on-the-rack controller. The SNAP-B3000-ENET Ethernet I/O brain is a compact I/O and communications processor that connects real-world analog, digital, and serial devices with Ethernet networks for monitoring, control, and data acquisition.
