FIRST STARTUP AND IP CONFIGURATION
At the rst startup the IP address is congured in static mode with address 192.168.90.101
By default the SW2 DIP-switch selectors are set to OFF.
In the case of conguration with an IP address retrieved from DHCP, and if a DHCP server is not present in your
network, the device, after 5 minutes from startup, will initialize with the IP address: 169.254.x.y where the x and y
values are the last two MAC address digits (see product side label).
N.B: through the software for the SDD (SENECA Discovery Device) Windows PC, downloadable for free from the
www.seneca.it/products/sdd site, it is possible to easily identify the device on the network and view / change the IP
address in a few steps (see USER manual for details).
WEB SERVER
To access the conguration web server, simply enter the product's IP address in your navigation browser and log
in with the following credentials:
User: admin Password: admin.
SW1 DIP-SWITCH SETTINGS
DESCRIPTION DIP 1 DIP 2
To polarize the bus on RS485, both SW1 DIP switch selectors
must be set to ON ON
NOT to polarize the bus on RS485, both SW1 DIP switch
selectors must be set to OFF OFF
Through DIP-SWITCH-SW1 it is possible to set the polarization of the bus relative to the RS485 port:
SW2 DIP-SWITCH SETTINGS
Through DIP-SWITCH-SW2 it is possible to set the IP conguration of the device:
DESCRIPTION DIP 1 DIP 2
To obtain the conguration from the Flash memory, both SW2
DIP switch selectors must be set to OFF
To reset the device to factory settings both SW2 DIP switches
must be set to ON
To force the device's IP address to the standard value of
SENECA ethernet products: 192.168.90.101

WARNING
The DIP-switch settings are read only at boot time. At each change, perform a restart.
DEVICE CONFIGURATION
R-GWR can be fully set up via integrated web server. The product programming and/or conguration tools, as well
as all the manuals, can be downloaded at the web address:
www.seneca.it/products/r-gwr.
For further information, refer to the USER manual that can be downloaded from the above site.

ELECTRICAL CONNECTIONS
Power supply:
Electrical power connections are available from
terminals 8 and 9. Power voltage must be between 10
and 40 Vdc or between 19 and 28 Vac (any polarity).
The upper limits must not be exceeded in order to
avoid serious damage to the device.
The power supply source must be protected from the
malfunctions of the module through an appropriately-
sized safety fuse.
RS232/RS485 switchable serial port:
To use the COM RS232 serial port, make the electrical
connections via the GND, RTS, Tx, CTS and Rx
terminals.
To use the COM RS485 serial port, make the electrical
connections via terminals A (+), B (-) and GND.
N.B: the indication of the RS485 connection polarity
(terminals A+ and B-) is not standardised and in some
devices may be inverted.
The gure alongside shows the key of the terminals.
N.B.: see the SETTINGS paragraph on page 4 in case
of communication problems.
Restart button:
The button is located between the SW2 DIP-switch and
the Ethernet port. To reboot the device, keep the key
pressed for 5 seconds. Release it when all the LEDs
light up.
RJ45 Ethernet port:
The R-GWR has an Ethernet 100 port with RJ45
connector in the lower part of the module.
