same IP address as the SV1115IPEXT before connecting it to the network, to avoid a
conflict. Should an IP address conflict occur with another device on the network, power
off the conflicting device or assign it another IP address before continuing the installation.
If you are configuring more than a single SV1115IPEXT using the factory default settings
on the WAN port, they cannot be connected to the network at the same time as they will
use the same IP address.
NOTE: Not all IP addresses are valid for a given subnet. If you are required to change
your subnet (and therefore IP address) to configure the unit, be sure the IP address you
choose is within the allowable range for the 255.255.255.0 subnet.
Once your computer is configured to the same subnet as the SV1115IPEXT, you can use
the IP address 192.168.1.123 to access the Web configuration system.
Terminal Configuration Using a Serial Cable
Configuring the SV1115IPEXT using a serial cable is the best choice if you need to pre-
configure the unit before attaching it to a network, i.e. when sending to a branch office,
customer site, etc. In general, the Web configuration is preferable because of its intuitive
interface and the fact that you do not have to be within close physical proximity to
perform the configuration. However, if you wish to use the serial cable method to
configure the SV1115IPEXT, you can use any typical communication software package
(UNIX: tip, cu, kermit, minicom; Windows: HyperTerminal, kermit).
You can use either serial port on the SV1115IPEXT to access the terminal configuration
tool; your choice will dictate the type of cable you will use to make the connection. The
DTE Serial port on the front panel requires the use of a null modem serial cable. The
DCE Serial port on the rear panel requires the use of a straight through serial cable.
Connect a female end of a serial cable to the serial port used for serial access on the
host computer. Connect the opposite end (male if connecting to the DCE Serial port,
female if connecting to the DTE Serial port) to the SV1115IPEXT. Configure the terminal
software with “8N1” settings:
Connection speed: 115200 bps
No. of bits: 8
Parity: None
Stop bits: 1
