J-Series Data Radio – User Manual
Issue 09-10
Introduction
Point to Point (PTP) connectivity using the UDP mode of the
embedded J-Series terminal servers is useful for PTP serial links
requiring low latency and high throughput.
Unlike the TCP mode of operation, there are no Client or Server
modes. Both ends of a PTP Serial via UDP are configured in a
similar way (with the exception of destination IP address and port
numbers).
More information on PTP Serial via UDP/IP(Unitcast) 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 PTP mode as described in the Point to Point Quick Start
Guide using the IP addresses as defined in the image above. The
following procedure assumes this has already been done.
1 - UDP Configuration (Unit A)
Connect your browser to the configuration web page for Unit A
using the IP address of Unit A and navigate 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 Point”
(f) Ensure the Remote IP Address is configured to be the
IP address of Unit B. (in the above example this would be
192.168.2.17)
Point to Point - UDP (Unicast) Serial Device Server Setup Guide
(f) Ensure the Remote IP Port is configured to be 30010
(g) Ensure the Local IP Port is configured to be 30010
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 Unit B.
2 - UDP Configuration (Unit B)
Repeat the steps as shown above in “1 - UDP Configuration (Unit
A)” with the exception of step (e).
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)
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.
3 - RS-232 Final Testing
The Point to Point via UDP Serial connectivity is now complete.
The RS-232 link can be tested using an RS-232 Serial Packet
Test Program such as LinkTest or by connecting your RS-232
application.
The PortA/B LED status can also be used to diagnose the PTP
via TCP Serial Link. A flashing RED LED means that RS-232 data
is being sent into the radio for transmission. A flashing GREEN
LED means that RS-232 data is being received from the link and
presented to the port.
