generating transaction files, or TCP/IP or OPOS protocol compatible.
2. Configure a static IP address or domain name on the POS device. If the POS device uses a
dynamic IP address, you should apply for a domain name from the DDNS service so that the
GV-System can always access the POS device by the domain name.

Note: Two kinds of DDNS programs are provided in the Software DVD: Dynamic DNS Service and
Local DDNS Server. For details see Chapter 11 Useful Utilities.
