4.2 HOW TO COMMUNICATE? A SIMPLE EXAMPLE
The SG-15
Colour
is a simple IP device in the local network, which accepts and
displays normal ASCII characters.
After scanning a bar code, it outputs it as a normal ASCII string.
The easiest way to communicate with an SG-15
Colour
right out of the box, without
any further configuration, is using a telnet session:
1 First, connect the SG-15
Colour
to your network (using a normal 1:1
Ethernet cable) or directly to your PC (using a crossed Ethernet
cable).
2 As you turn on the SG-15
Colour
, the 'Offline' message will flash on the
display. It will continue to do so, until you've made a software
connection to it.
3 By default, the SG-15
Colour
is configured as TCP client, having DHCP=ON
(the IP address 192.168.1.200 if no DHCP service)
and listening to port 9101.
4 Make sure that your PC has an IP address in the same IP range, e.g.
192.168.1.250
5 You should be able to 'ping' the SG-15
Colour
now, by entering:
Ping 192.168.1.200
If it's not successful, you should double check the IP address of
your PC and all cable connections.
Also, make sure the SG-15
Colour
is configured to it's default settings.
You can force this as described in Appendix D.
