IB-151 Ethernet/USB Interface
USB (USB-B) and standard Ethernet (RJ-45) connections can be made through the
IB-151 interface which plugs directly into the host port of the Quadrus EZ. The IB-151 has
an second 25-pin port to pass through all but the RS-422/485 connections.

Important Notes
For ethernet connection, the IB-151 is recommended for the following reasons:
• Protection components are installed within the IB-151 to address ethernet susceptibility to line transients
and electrostatic discharge (ESD) that can cause communication dropouts and connection termination.
• The IB-150's matching cable does not provide the proper matched impedance that the standard CAT 5
cable provides, thus allowing higher emission levels which exceed Class A CE limits and possible further
signal degradation.
