J-Series Data Radio – User Manual
Point to Multi-Point with Peer to Peer - UDP (Multicast to Multicast)
Serial Device Server Setup Guide
Introduction
Point to Multi-Point (PTMP) with Peer to Peer connectivity using
the UDP mode of the embedded J-Series terminal servers is useful
for PTMP serial links requiring peer to peer connectivity.
More information on PTMP Serial with Peer to Peer via UDP
(Multicast to Multicast) can be found in Part D of this user manual.
The following information will guide you through the minimum
steps required to configure this feature in the J-Series. Refer to the
HTML programmer for more information about each item.
Please ensure you have already configured the J-Series radios for
PTMP mode as described in this manual (Alternatively you can use
the PTMP wizards). Ensure you have configured the units with the
IP addresses as specified in the diagram above.
Ensure the Default Gateway in the Network Parameters
configuration of all radios is configured as shown.
1 - Configuration (Unit A)
Connect your browser to the J-Series configuration web page of
Unit A (192.168.2.16) and select to the “Configuration” page and
then select the “Serial Port A” option.
(a) Ensure the Mode is configured to be “Serial Device Server”
(b) Ensure the Character Layer matches the configuration of the
external serial device you are connecting to the J-Series Serial
Port. The default is 9600,8,N,1.
(c) Ensure the Packet Layer is set to “Standard”
(d) Ensure the Protocol is configured to be “UDP”
(e) Ensure the Network Type is configured to be “Multipoint to
Multipoint”
(f) Ensure the Local IP Address is an address from the designated
multicast range of IP Addresses, in this example we are using
224.140.1.1 (this is the multi-cast address as configured in the
multi-point units B & C. In this mode, all the multi-cast IP addresses
are the same)
(g) Ensure the Local IP Port is configured to be 30010
(h) Ensure the Remote IP Address is an address from the
designated multicast range of IP Addresses, in this example we
are using 224.140.1.1 (this is the multi-cast address as configured
in the multi-point units B & C. In this mode, all the multi-cast IP
addresses are the same)
(h) Ensure the Remote IP Port is configured to be 30010
(i) Ensure the Time to Live is configured as “Restrict to same
Subnet”
Click on Activate Configuration.
Once the web browser has activated the new configuration and
then returned to the Configuration page, the configuration of Unit A
is now complete. The next step is to configure the Multi-point Units
B & C.
2 - Configuration (Units B&C)
Repeat the steps as shown above in “1 - Configuration (Unit A)”
with the exception of default Gateway Address as found in the
“Configuration -> Network Parameters”
The Default Gateway IP address should be the IP address of
your Gateway in the network. In this example, the Access Point IP
address is defined as the Gateway (192.168.2.16).
