4.5 Verify Communication By Performing a Telnet Session to Port 10001
This will test the port used by Doors32/Doors.NET to communicate to the LAN device.
4.5.1 Set the Doors32 Remote Site Port Number
This section applies only to Doors32 systems at version 5.20 or earlier.
In these software installations the default Remote Site Port Number default is 0. This value needs to be changed to 10001
for proper operation.
1. In Doors32, navigate to the Setup > System window.
2. Click the Network Config tab.
3. Click the TCP/IP Port radio button.
4. Enter 10001 in the Server’s Ethernet Port Number.
5. Click Save.
6. Close Doors32 to ensure the program applies the new value.
4.5.2 Verify Communication
The telnet command is preferred over the ping command in testing communications because the telnet command will give
a specific response from the device whereas the Ping command may give a response from a different device (i.e. if there is
a duplicate address on the net the Ping may still get a reply).
1. In the command prompt window type in, telnet [IP Address] 10001 <enter>.
- If telnet connects, a blank screen and a blinking cursor will appear. The link LED on the LAN-520 AESP will blink
on and off indicating that port 10001 is open. Close the command prompt window and the LED should stop
blinking.
