DAISY-CHAIN (R-32DIDO-2 / R-32DIDO-2-P ONLY)
IT IS NOT ALLOWED TO CREATE LOOPS WITH ETHERNET CABLES
Using the daisy-chain connection it is not necessary to use switches to connect the devices.
The following examples show the correct connections.
There must be no loops in the Ethernet cabling, otherwise the communication will not work. The modules and switches must be
connected eliminating any loops. The following examples show the incorrect connections.
The LAN fault-bypass function allows you to keep the connection between the two Ethernet ports of the device ON, in the event of a
power failure. If a device turns off, the chain is not interrupted and the devices downstream of the switched-off one will still be acces-
sible. This function has a limited duration: the connection remains active for a few days, typically 4. The fault-bypass function requires
that the sum of the lengths of the two cables connected to the switched off module is less than 100m.

ETHERNET CONNECTION RULES
For the Ethernet cabling between the devices, the use of the unshielded CAT5 or CAT5e cable is required.
CAT6 for industrial environments.
FACTORY IP ADDRESS
The default module IP address is static: 192. 168. 90. 101
WEB SERVER
To access the maintenance Web Server with the 192.168.90.101 factory IP address
(Default user: admin; Default password: admin) http://192.168.90.101
DO NOT USE DEVICES WITH THE SAME IP ADDRESS IN THE SAME ETHERNET NETWORK.

DIP- SWITCH SW1: through DIP-SWITCH-SW1 it is possible to set the IP conguration of the device:
DESCRIPTION DIP 1 DIP 2
To obtain the conguration from the Flash memory, both SW1 DIP
switch selectors must be set to OFF
To reset the device to factory settings both SW1 DIP switches must
be set to ON
To force the device's IP address to the standard value of SENECA

Reserved
DIP - SWITCH SETTINGS
The DIP-switch settings are read only at boot time. At each change, perform a restart.
DIP-SWITCHES are located on the back of the device.
To access the DIP-SWITCH it is necessary to remove the bottom of the instrument.
