ES582.1 - User’s Guide

Timestamp
The ES582.1 assigns a timestamp to the CAN messages. The measured data
acquired by the ES582.1 module is synchronized by the INCA application soft
-
ware with signals of other ECUs and measuring modules at high speed.
Feature
The CAN applications supported by the ES582.1 are located in an overview in
chapter 6.6.2 on page 31.
Bus terminating resistor
The CAN interface requires the use of bus terminating resistors in both operat
-
ing modes. According to the CAN specification, one bus terminating resistor
each of 120 ohm is required at the two open ends of the bus. It must be con
-
nected to the cable or the plug. ETAS offers cables and terminating resistors of
120 ohm to set up CAN networks.
Some CAN networks are already terminated (e.g. inside a vehicle), so that no
additional termination is required.
Minimum requirements for the CAN connections
At least the following connections are required for a connection to the CAN net
-
work:
• Pin 2 CAN Low
• Pin 7 CAN High
• Pin 6 or Pin 3 GND (one of the pins can optionally be connected)
The ground connection (GND) must be identical with the ground connection of
the other CAN nodes on the bus.
Y-cable
A Y-cable (CBCF100, see also 7.1 on page 34) allows access of both CAN inter
-
faces to the CAN bus.
3.4.2
USB Port
The module is firmly connected with a cable with USB connector type A for
connection to a USB 2.0 port of a PC or a drive recorder.
NOTE
The module must be operated directly on the USB 2.0 connection of a PC, a
drive recorder or an active hub whose USB interface meets the requirements
listed in the table in chapter 6.6.1 on page 29.
The use of USB cables for extending the connection between ES582.1 and PC
or drive recorder is not allowed.
