13. INSTALLING MULTIPLE DEVICES IN A NETWORK USING THE
"DHCP FAIL ADDRESS".
When the Gateway is configured with DHCP enabled but does not receive the DHCP server configuration within
2 minutes then it assumes a fail address.
This fail address is 169.254.x.y where x.y are the last two values from the MAC address.
In this way, if you force all devices to DHCP, you can install on the network even if there is no active DHCP
server.
When the fail address has been activated (the relative LED stops flashing), you can launch the "Seneca
Discovery Device" software and force the preferred IP address to all devices.
14. THE DB9 RS232 CABLE
The DB9 CABLE RS232 CABLE can be obtained from Seneca (it can also be purchased from the e-commerce
website www.seneca.it) for connection with a DB9 RS232 device.
