Ports
All ports of the ES400 measuring modules are on the front of the device (see
Fig. 3-2 on page 17).
The LEMO and Souriau connectors used adhere to protection class IP67. All ports
are reverse-polarity protected due to the exclusive use of coded LEMO or Souriau
connectors.

3.4.1
“Sensor” Port
The front of the ES415.1 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.
3.4.2
Daisy Chain Ports (“IN”, “OUT”)
The modules are connected using a daisy chain topology. This means each mod-
ule 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 mod-
ule:
• “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.
