Ethernet
The unit is equipped with an ethernet RJ45 port (see Figure 9). Connect Cat5 or better ethernet cable.
This provides a 10/100 ethernet connection. Ethernet communication includes ethernet connectivity to
the charger for monitoring and configuration via the SENS Setup Utility, Modbus TCP/IP (optional) and
DNP3 (optional).

Configure TCP/IP Address
Configure TCP/IP settings using the SENS Setup Utility or the keypad. To adjust settings using the
keypad, ensure the access level is set to allow adjustments. Set the IP address as desired. It may
take up to 10 seconds for the network setting changes to apply. A TCP/IP address of 0.0.0.0
implies DHCP (Dynamic) addressing. Adjust the Gateway and Subnet Mask values as required.
The displayed Hardware Address is the MAC address corresponding to the Ethernet interface. This
value is not adjustable.

SENSbus Connection
The unit is equipped with three SENSbus RJ45 ports (see Figure 10). This connection is used to
interconnect SENS specific devices.
