ES4440.2 Compact Failure Simulation Module - User’s Guide 25
ETAS Hardware Features
2.6 Master/Slave Operation of Several ES4440.2 Systems
An ES4440.2 Compact Failure Simulation Module has 80 channels – this number
is sufficient if, for example, failures are to be simulated for the outputs of an
engine ECU.
If, however, inputs and outputs of an ECU are to be tested simultaneously, a
second ES4440.2 Compact Failure Simulation Module is required.
In extreme cases, up to 15 slave systems can be connected to a master system.
For this purpose, the following lines/signals of the master must be connected to
the slave systems:
• The synchronization signals of the multiplexer relays (”SYNC” connector
on the front panel, see Fig. 2-5 on the left)
For details of the pin assignment of this connector, refer to section
"”SYNC” Connector" on page 31.
• The lines of the failure rails (”Rail 1/2” connector on the rear of the device
(Fig. 2-5 on the right)
For details of the pin assignment of this connector, refer to section "”Rail
1/2” Connector" on page 33.
