CHAPTER 4: SETPOINTS DEVICE889 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL 4–29X = (modulo 242 of the last 3 digits of the serial number) + 12Example: A unit has a serial number of MJ3A16000405, the default IP address would be192.168.0.175 (where 405 mod 242 = 163 + 12 = 175).This is to ensure uniqueness of the default IP address for all 8 Series devices present on onewireless network and it creates a usable address space from 192.168.0.12 to 192.168.0.253for 8 Series devices.NOTENOTE:From the remaining range of unicast addresses 192.168.0.1 to 192.168.0.253, at least twoare going to be used for the AP and a laptop installed with the EnerVista software, whichwill be used to configure the 8 Series devices. The AP should be configured with theaddress 192.168.0.1 and mask 255.255.255.0 and have DHCP enabled with a DHCP rangefrom 192.168.0.2 to 192.168.0.253. This allows laptops, iPads and any other devices toconnect to the local network without the need to statically configure their own IP addressand mask.WiFi GWY IP AddressThe setting specifies the address of the access point AP which the 8 Series device uses forcommunicating over WiFi.WiFi SecurityThe setting enables WiFi security. If set to “None”, there is no security and all traffic is open.By default WiFi Security is set to WPA2-PSK.WiFi SSIDThe SSID is the public name of a wireless network. All of the wireless devices on a WLANmust use the same SSID in order to communicate with each other. The default for the SSIDis provided by the vendor with the shipment of any new 8-Series device. It isrecommended that the customer modifies this name as needed after initial startup, toensure unique SSIDs if several WLANs are configured.NOTENOTE:SSID broadcast should be disabled on AP. This provides some extra protection by requiringa user to know an SSID before the user can connect to the device and making it harder forcasual outsiders looking for wireless networks to find the device and attempt to connect.WiFi WPA2 PassphraseThe WPA2 Passphrase is used for generating the encryption key. The same passphrasemust be set on AP and on all devices communicating on the same WLAN. The 8-Seriesdevice supports a string of up to 14 printable ASCII characters. Internally a 256-bit key iscalculated by applying the PBKDF2 key derivation function to this passphrase, using theSSID as the salt and 4096 iterations of HMAC-SHA1.The 8-Series devices are configured with a default passphrase, which is provided by thevendor with the shipment of any new 8-Series device.When choosing a new passphrase, the password complexity rules of CyberSentry must beused (see CyberSentry details in the relay Instruction manual).This field is visible only if the security is set to WPA2-PSK.NOTENOTE:Ideally the passphrase should be set through EnerVista and not directly from the Keypad,where there are limitations in terms of space and types of characters supported. However,for convenience, the key setting is available from the Keypad as well.
