How to resolve a connection error between your Oracle (Opera) PMS and the Adyen payment terminal.
If your Oracle (Opera) Property Management System (PMS) cannot connect to your payment terminal and displays one of the following error messages:
"Issuer or switch inoperative (01)"
Follow the steps below to troubleshoot and resolve the issue.
Step 1: Check the Payment Terminal
-
Ensure the payment terminal is functioning properly.
-
Try restarting the terminal to see if this resolves the issue.
Step 2: Restart the Oracle Payment Interface (OPI)
-
Restarting the OPI service may resolve the issue.
-
This step should be performed by your system administrator or with assistance from Oracle Support.
-
Note: Restarting OPI requires server access.
Step 3: Verify Terminal and Network Configuration
If restarting OPI doesn’t resolve the issue, continue with the following checks:
Check Terminal ID and IP Address Settings
-
Open the Opera Workstation Register and verify:
-
The Terminal ID
-
The Payment Terminal IP address
-
-
These values should match the configuration in Adyen and be linked to a static IP address.
Perform a Ping Test
-
Ping the payment terminal from the server to test network connectivity:
-
If ping fails → the issue is likely network/server-related (e.g. static IP misconfiguration).
-
If ping is successful → the issue may lie within Opera configuration (e.g. IP address, serial number, or cashier ID).
-
Step 4: Confirm Reg.Term.ID and Port Access
-
Ensure Opera has not changed the Register Terminal IDs on the workstations.
-
Confirm that you can connect from the OPI server to the payment terminal on port 8443 (default port for Adyen).
Step 5: Restart the OPI Service After Configuration Changes
-
If you've updated any settings, restart the OPI Service (Windows service) to apply the changes.
By following these steps, you should be able to identify and resolve the cause of the payment terminal connection issue in your Oracle (Opera) PMS system.
