3 Getting started
3.1 CONFIGURING THE SERIAL TO ETHERNET CONVERTER
If GPRS modem is used for remote communication, STER PMU device automatically configures all necessary
parameters. In that case, you can skip this chapter and continue powering on the device.
For the SENA PS110 Serial to Ethernet converter, it is important to manually configure its IP address to match the
appropriate LAN subnet before connecting it. This configuration needs to be done using a PC, either through an
RS232 serial connection while the PS110 device is in Console mode, or by connecting the device to a PC using a
crossover LAN cable.
Before configuration, you need to determine which IP settings the device should have, in order to operate when
connected to your LAN equipment. If the device is connected to a network with a DHCP server (most routers
support this protocol) the IP settings are assigned automatically by the DHCP server.
Alternatively, a static IP can be configured to match advanced network requirements, in which case there are four
parameters which need to be known before continuing:
1
IP address
A static IP address acts as a permanent identification number. It is required that the
selected IP address is both unique and valid in a network environment.
2
Subnet mask
A subnet represents the range of IP addresses for all the network hosts in one
geographic location, such as a building or local area network (LAN). PS110 will use
the subnet mask setting to verify the origin of all packets. If the desired TCP/IP host
specified in the packet is in the same geographic location (on the local network
segment) as defined by the subnet mask, the Pro Series will establish a direct
connection. If the desired TCP/IP host specified in the packet is not identified as
belonging on the local network segment, a connection is established through the
given default gateway.
3
Default gateway
A gateway is a network point that acts as a portal to another network. This point is
usually the computer or computers that control traffic within a network or a local ISP
(Internet service provider). PS110 uses the IP address of the default gateway
computer to communicate with hosts outside the local network environment.
4
Primary and
Secondary DNS
The DNS (Domain Name System) server is used to locate and translate the correct IP
address for a requested web site address. A domain name is the web address (i.e.
www.yahoo.com) and is usually easier to remember. The DNS server is the host that
can translate such text-based domain names into numeric IP addresses for a TCP/IP
connection.
The IP address of the DNS server must be able to access the host site with the
provided domain name. The Pro Series provides the ability to configure the required
IP addresses of both the Primary and Secondary DNS server addresses (the
secondary DNS server is specified for use when the primary DNS server is
unavailable).
If unsure, please refer to your network administrator before continuing. Specifying wrong IP settings is the
most likely reason for connection issues.
3.1.1 PERFORMING A FACTORY RESET OF THE DEVICE
Before starting, it is advisable to make a full factory reset of the PS110 device.
To do that, make sure that the device is powered on by connecting the provided power charger to the device. The
Power LED on the opposite side of the device should indicate that the device is powered on.
