▒ IP address Configuration
IP address means an inherent distinguishable address which is given to all communication
networks to the Internet and the products that is connected to communication networks.
When using HMCE-103 in user network environment, active IP address is needed. When IP
address is not given, please make inquiries to the system administrator to get an active IP
address for HMCE-103. When connecting to HMCE-103 to the network, you must have an
inherent IP address.
When setting an IP address in HMCE-103, users support 2 following internet protocols.
•Static IP
•DHCP (Dynamic Host Configuration Protocol)
Static IP address, also known as fixed IP address, is an Internet address which can be
accessed from Host or Lauter through Internet.
DHCP, also known as IP address, is used to send out notification from LAN in office to PC
about set-up information regarding TCP/IP. It is also a protocol to set up remotely each of
host of important network parameter and set up details with using the server setting.
※ When releasing from factory, IP address is set up as default
“192.168.1.15” for HMCE-103.
Following items are user settings for variables and users use it by changing the setting value
in accordance with network environment.
▒ Registered Port
Registered port can be arranged in IANA and it can be used in programs which general
users use for most of systems or user process. Port is used in TCP[RFC793] to indicate a
logic connection’s ending which makes a long time conversation. Service connection port is
defined as a purpose to provide a service to unknown invoker. Registers of IANA use this
port in community for convenience. This kind of port allocation within available range is used
in UDP[RFC768] Range of registered Port is within 1024-49151.
Please visit IANA website for more information.

Primary DNS / Secondary DNS(Optional)
① Static IP address can take a role as fixed and permanent distinguishable number. This
number is assigned from computer and it is also a address It is possible for computer to
distinguish and communicate in the network using this type of IP address. Thus, selected IP
address should be absolutely inherent and valid in the network environment.
The type of 192.168.1.x IP address is a private address bu because ISP (Internet Service
Provider) is not assigned. In order to apply HMCE-103, it should be able to exchange the
data through public network like Internet, and official IP address should be assigned in this
case. Official IP address is generally purchased or leased from local ISP
② Subnet mask means all network hosts in the same geographical location and one building or
in the same LAN. When there is a packet going out through network, you should check
on if there is a packet assigned from TCP/IP host in the local network area through
subnet mask. When address is in the same network area as HMCE-103, it is directly
connected through physical address. If it is not, it is connected through basic gateway.
Caution
③ Default gateway is a network contact which takes an entry role to other network.
Computer which controls traffic within network or in the regional ISP is a gateway node.
In order to connect to host outside the local network environment, Pro Series should know
basic gateway computer’s IP address. Please make inquiry to network administrator for
detailed information about network Gateway IP address.
④ For Primary DNS / Secondary DNS, if users want to visit the website, computer will ask
DNS (Domain Name System) Server about correct IP address and with using the answer
from the question, it connects to the webserver. DNS is a way to convert to IP address by
identifying the Internet domain name. DNS Server is a host that converts to numeral IP
address in order for text based domain name to connect to TCP/IP If you use the
HMCE-103’s DNS function, you should set up the DNS server’s IP address for connecting
to host under the name of domain.
⑤ Network administrator centrally manages IP address’s allocation in the organization’s
network for DHCP. Also, DHCP is a communication protocol which is available for
automation. For DHCP, network administrator manages and allocates the IP address and if
computer is plugged in the other network, the new IP address is automatically transmitted.
In DHCP mode, variable is not automatically set up for all network related to HMCE-103
including DNS Server.
Caution
EX) When changing Baud rate to 115200.
Check out if Baud rate is changed properly.

▒ Port number Configuration
▒ Well-Known Port
Port number is distinguished by well-known port, registered port, and dynamic or personal port.
• Well-known port is from 0 to 1023.
• The registered port is from 1024 to 49151.
• Dynamic or personal port is from 49152 to 65535.
Well-known port is allocated from IANA and only programs which system (or route)
processor or authorizers use are available in most of systems. Port is used in TCP[RFC793] to
indicate a logic connection’s ending which makes a long time conversation. Service
connection port is defined as a purpose to provide a service to unknown invoker. Connection
port is also known as “Well known port” This type of port allocation within available range is
used in UDP (RFC768). Allocated port use the small part of available port numbers Allocated
port for several years is within a range from 0 ~ 255. Recently, the range of allocated port
which is managed by IANA extended a range from 0 ~ 1023.
