Release of 170ENT11001 RoHs Version Ethernet Communication Adapter

The purpose of this resolution is to announce that a new RoHs version 170ENT11001 was released in September 2009.

Product Line

What is RoHs?
RoHs is the acronym for Restriction of Hazardous Substances. RoHS, also known as Directive 2002/95/EC, originated in the European Union and restricts the use of specific hazardous materials found in electrical and electronic PRODUCTS. The substances banned under RoHS are lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE).


  • Identifying a RoHs version 170ENT11001
    Since the part number is the same for both a RoHs and non-RoHs communication adapter, a RoHs compliant 170ENT11001 is identified by adapters laser marked with an SV at v1.10 or higher. Non-Rohs versions will always have an SV less than 1.10. There are no other physical differences between the two adapters.

    One other method to determine a RoHs and non-RoHs version is through the communication adapters web pages. Once logged in, select Momentum I/O Configuration and Diagnostics, then select Momentum I/O Properties.  If it is a RoHs version, the Adapter Part Number will display: 170ENT11001 (RoHS).  A non-RoHs version will only display the part number: 170ENT11001.

  • Replacing a non-RoHs 170ENT11001 with a RoHs 170ENT11001
    The new RoHs version 170ENT11001 is a direct replacement for the non-RoHs version. There are no functional differences between RoHs and non-RoHs 170ENT11001's.

  • Firmware
    The minimum version firmware for the RoHs 170ENT11001 is v1.10.
    This firmware is NOT for use in the non-RoHs ENT11001's.

    Future firmware updates for the RoHs ENT11001 will be any version greater than 1.10.
    Any non-RoHs firmware versions released in the future will always be less than 1.10.

    The following fixes and enhancements were made to firmware version 1.10:
    1. The default gateway address on the ENT V2 when read by SNMP was incorrect.
    2. The 170ANR12091 was not recognized or properly displayed on the 170ENT11001's web pages.
    3. New option added to the web page to disable Bootp/DHCP functionality.

  • Performance
    RoHs version communication adapters use a Cirrus Logic processor instead of a NET50 processor that is used in the non-RoHs. The faster Cirrus results in improved performance over the Net50.
