CONNECTOR FUNCTIONS AND INTERFACE CABLES
The table below notes the function of each connector, as well as mating connectors and cables,
and the page where a detailed pinout or further information is available.
Note: VersaLogic adapter cables for the EPM-4 are available in RoHS compliant and
RoHS noncompliant versions. Compliance or noncompliance is indicated by the
part number prefix. “CBR” indicates RoHS compliance. “CBL” indicates RoHS
noncompliance. For applications that require RoHS compliance, use only the RoHS
compliant (“CBR” version). Availability of RoHS noncompliant cables may be
limited.
