ES910.3-A - User’s Guide 37
ETAS Functional Description
4.12 ECU Interface (ECU)
The ES910.3-A has one ECU interface which is routed to a 4-pin ECU connector
(Lemo socket) on the back panel. The ECU interface is galvanically isolated from
the other interfaces of the ES910.3-A.
4.12.1 Connecting the Hardware and Configuration
Hardware can either be connected directly to the ECU interface or be operated
at an externally connected switch.
Operation without external Switch at the ECU Interface
The ES910.3-A can optionally access the following hardware directly if no exter-
nal switch is connected to the ECU interface:
• an XETK or an ECU with Ethernet interface, or
• a text bench computer with iLinkRT
TM
interface.
To access the directly connected hardware, the Ethernet Interfaces "PC" and
"ECU" of the module must be connected with each other via the internal (soft-
ware) switch of ES910.3-A (Ethernet layer 2 software bridge).
Operation with external Switch at the ECU Interface
If the ECU interface is connected with an external switch, the following hardware
can be connected to the external switch and, at the same time, be operated at
the ES910.3-A:
• several XETKs or several ECUs with Ethernet interface, or
• additional ETAS modules, or
• one or several interfaces with the iLinkRT
TM
protocol, or
• a combination of these Interfaces.
If hardware is connected directly at the ECU interface, the internal switch on
the web interface of the module must be configured with the setting "L2
Bridge on" (see chapter 5.6.6 on page 63).
If an external switch with iLinkRT interface is used at the ECU interface, the PC
or Drive Recorder may not be directly connected with the PC interface of
ES910.3-A. PC or Drive Recorder must be connected to the external switch (see
Fig. 4-8 on page 38).
