4.4.1
“Sensor” Port
The front of the ES411.1 features a 22-pin Souriau port to which four sensors
can be connected using a adapter cable. An individual sensor power supply
port is available for each sensor.
The use of a “cable tail” or “whip” solution with just one connector makes it
possible to change the modules quickly within complex test setups.
4.4.2
Daisy Chain Ports (“IN”, “OUT”)
The modules are connected using a daisy chain topology. This means each
module has an explicit input socket and an explicit output socket. The Ethernet
data line and the supply voltage are routed through the daisy chain ports of the
module:
• “IN” (input)
• “OUT” (output)
The PC, the modules ES523, ES59x, ES600.2, ES891, ES910.3 or the Drive
Recorder ES720 are connected at the “IN” port (input). The “OUT” port (output)
is connected to the following module of the ES400 line or remains free on the
last module of the chain.
