J-Series Data Radio – User Manual
Introduction
Point to Multi-Point (PTMP) connectivity using the UDP mode of
the embedded J-Series terminal servers is useful for PTMP serial
links requiring low latency and high throughput.
In PTMP via UDP there are no Client or Server modes. All units in
a PTMP Serial via UDP are configured in a similar way (with the
exception of destination IP address and port numbers).
More information on PTMP Serial via UDP (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 the Access Point is configured as shown.
1 - UDP Point 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 “Point to Multi-
Point”
(f) Ensure the Node Type is configured to be “Point”

(g) Ensure the Remote IP Address is an address from the
designated multicast range of IP Addresses, in this example we are
using 224.168.1.1 (this is the multi-cast address as configured in
the multi-point units B & C)
(h) Ensure the Remote IP Port is configured to be 30010
(i) Ensure the Local IP Port is configured to be 30010
(j) 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 - UDP Multipoint Configuration
(Units B&C)
Repeat the steps as shown above in “1 - UDP Point
Configuration (Unit A)” with the exception of steps (e) & (f) and a
new step for the Local IP Address.
(a) Ensure the Node Type is configured to be “Multipoint”
(b) Ensure the Remote IP Address is configured to be the
IP address of Unit A. (in the above example this would be
192.168.2.16)
(c) Ensure the Local IP Address is an address from the
designated multicast range of IP Addresses, in this example we are
using 224.168.1.1 (this is the multi-cast address as configured in
the multi-point units B & C)
Click on Activate Configuration.
Once the web browser has activated the new configuration and
then returned to the Configuration page, the configuration of Unit B
is now complete and the process can be repeated for Unit C (which
is identical to Unit B)
