The EIU directly interfaces with the ECP 230 VDC Trainline power supply and is connected to the NIU-II. It also acts as a gateway between the NIU-II and Trainline Network to allow HEU/LCM messages to be passed between the Trainline network devices and the NIU-II.
NOTE: The previous Locomotive ID (LID) functionality is now integrated into the cable between the EIU and NIU-II. This cable has an integrated static memory for maintaining the Locomotive Static parameters specific to each customer application.
