4.3.9 Access Control (continued)
MAC Address:
This is also called Hardware address or Ethernet address, which is
assigned to the Receiver at production. The MAC (Media Access Control) address is the
Receiver’s unique hardware number and is not changeable.
IP Address:
The IP (Internet Protocol) address is a 32-bit number that identifies each
sender or receiver of information that is sent in packets across the Ethernet or the
Internet. The Receiver’s default IP address is
192.168.1.200
. The Receiver’s IP address
should be changed to fit user’s networking environment. Consult with your IT department
for obtaining an IP address.
The DHCP will be enabled in the Receiver if its IP address is set to
0.0.0.0.
The DHCP can also be enabled by setting the DIP switch
#3
to
ON
position.
Gateway Address:
A gateway is a network point that acts as an entrance to another
network. A gateway is often associated with a router, which knows where to direct a
given packet of data that arrives at the gateway. If the Receiver is sending packets to
another network node that is not on the same network on which the Receiver is
connected, a gateway address needs to be given to the Receiver. The gateway address
should be the IP address of the router connected to the same LAN to which the Receiver
is connected. The Receiver default gateway address is
0.0.0.0
. Consult with your IT
department for obtaining a gateway address.
Subnet Mask:
It’s a 32-bit number that is used to determine which part of the IP
address is the network portion and which part is the host portion. The Receiver default
subnet mask is
255.255.255.0
. Consult with your IT department for obtaining a subnet
mask.
Save:
Saves any changes for above settings.
Reset:
Pressing the Reset button will set all the fields back to their original values.
Network Reset:
Reboots the embedded server. Note that all updated network
parameters take effect after reboot.
Changes made in the "Access Control" page can be saved permanently by
pressing the
Save
button and power recycling the Receiver (press
Network
Reset
button).
4.4 Telnet Setup
In the Configuration page, set the TCP Connections to 1 - 5 other than 0, and use a
telnet simulation program to connect to the Receiver (using Port 2000). The command
can be sent to query the Receiver and you will get a response back.
For a list of commands refer to ASCII/TELNET commands Table in
Appendix F
.
4.5 HTTPget Program
The Httpget software is used to send a single HTTP or TCP request to the Receiver. In
contrast, the telnet or Hyperterminal programs allow a continuous connection with
multiple requests to be sent to the Receiver.
Generally HTTPget is used for simply programming an IP address to the Receiver or for
quickly obtaining a reading from a Connector/Transmitter.
The Receiver must be configured from the configuration web page so that the "TCP
Connections" indicates any number between 1 and 5. Make sure that the Port Field
number indicates 2000.
