Configure Front and Rear TV Connections on a New Install

Use this procedure when new front or rear display computers do not connect to the Retro C, show stale production information, or fail after upgrading from the older Java environment. The display startup script, Java path, application memory, Retro C software file, and network ports must agree.

Support procedure: These steps modify Linux startup and XML configuration files. Enventek Support or a technician familiar with the system should make the changes. Back up every file before editing it.

Record the current configuration

1. Save copies of startup.sh, Front.xml, and Catch.xml.
2. Record the current Java path and memory value in startup.sh.
3. Record the Retro C software version and whether a Linear PickLine is connected.
4. Confirm the IP addresses and physical network links for the saw, front display, and rear display.

Update startup.sh

1. Remove the obsolete Java option line containing -XX:+UnlockCommercialFeatures .
2. Increase the existing application-memory setting by the amount specified by Enventek Support. The installed value varies, so record it before adding 1.
3. Change the Java folder reference from Java 8 to Java 17.
4. Review the edited command for line-continuation characters, spaces, and file paths before saving.

Confirm the Retro C application file

The display must use the compatible Retroc.jar file. If the correct file is not already present, Enventek Support may use SFTP to obtain the matching file from the saw. Preserve the current file as a rollback copy before replacing it.

When a Linear PickLine is attached

• In Front.xml and Catch.xml, change the applicable connection to port 81.
• In Front.xml, uncomment and correct the two required connection lines that are disabled in the original new-install configuration.
• Do not change unrelated ports or XML entries.

Restart and verify

1. Restart the display software or computer so the startup and XML changes are reloaded.
2. Confirm that the front and rear displays connect without a Java or socket error.
3. Verify that board, setup, and production information updates as the Retro C advances.
4. If one display works and the other does not, compare its XML, Java path, network link, and application file with the working display.
5. If the display no longer starts, restore the backup files and contact Enventek Support with the startup error.
