Note: When using the DB25 connector for RS232, the connector is DTE. To perform as DCE, use the
appropriate interface adapter cable. Refer to Chapter 4, Cable Specifications & Adapters for
more information about specific cabling parameters.
The six RJ11 LAN connectors are used only with the Hypercom RS485 terminal LAN. The six
RJ11 line connectors are used with adapter interfaces or cables to support media in
addition to the standard RJ11 dial capability. For example, UTP Token Ring or Ethernet,
DS1/T1, DDS, and 4-wire leased line.
Also available is a bus extension connector on the rear of the IEN 3000 chassis. Refer to
Chapter 5, IEN 3000 Configuration for more information about IEN 3000 chassis bus
extension capabilities.
