Step-by-Step Resolution
- Check Lexi Status
- Log into Lexi dashboard.
- Verify active subscription.
- Encoder Configuration
- Ensure Lexi is selected as caption source.
- Validate GPI trigger settings.
- Test Workflow
- Send test captions.
- Monitor output on downstream decoder.
Escalate if: Captions fail despite correct configuration.
Network/Firewall/Connectivity Problems
Common Issues
- Encoder cannot connect to iCap or Lexi.
- Firewall blocking ports.
Best Practices
- Maintain updated port and protocol documentation.
- Liaise with customer IT for firewall changes.
Step-by-Step Resolution
- Ping Test
- Test connectivity to iCap/Lexi servers.
- Firewall Check
- Confirm required ports are open (e.g., TCP 5000–5002).
- Whitelist encoder IP.
- DNS Verification
- Ensure DNS resolves iCap/Lexi domains.
Escalate if: Connectivity fails after firewall adjustments.
Account Management, Licensing & Support Contracts
Common Issues
- Missing license keys.
- Support renewal confusion.
Best Practices
- Keep license provisioning scripts ready.
- Communicate renewal timelines proactively.
Step-by-Step Resolution
- Verify Account
- Check CRM for active contract.
- Provision License
- Generate key via licensing portal.
- Apply key in encoder settings.
- Confirm Activation
- Restart encoder and validate feature availability.
Escalate if: License activation fails repeatedly.
Captioning/Output & Special Character Issues
Common Issues
- Garbled captions.
- Unsupported Unicode characters.
Best Practices
- Use UTF-8 encoding where possible.
- Apply compliance filters for special characters.
Step-by-Step Resolution
- Check Encoder Output
- Validate CC stream format.
- Apply Filters
- Enable character substitution for unsupported symbols.
- Test Downstream
- Confirm captions display correctly on decoder.
Escalate if: Issue persists across multiple workflows.
Shipping/Repair Logistics
Common Issues
- Delayed shipments.
- Customs clearance issues.
Best Practices
- Track RMA and loaner inventory.
- Communicate timelines clearly.
Step-by-Step Resolution
- Confirm Shipment
- Check tracking details.
- Update Customer
- Provide ETA and customs status.
- Arrange Loaner
- If delay exceeds SLA, dispatch loaner unit.
Additional Frequently Asked Questions
What is the HD492 encoder used for?
The HD492 is a broadcast‑grade encoder supporting live captioning, Lexi AI captioning, and multiple caption input/output formats.
How do I update HD492 firmware?
Firmware updates are applied using .tar.bz2 files via USB or the web interface.
Can firmware be downgraded?
No. Downgrades are not supported once an update is applied.
Why does the encoder show “F1 Blocked”?
This indicates upstream captions are blocked, often because Lexi is active or no audio is detected.
Why are captions not appearing on output?
This may be due to decoder settings, incorrect service selection, or downstream equipment issues.
Does HD492 support 3G‑SDI Level B?
No. Only Level A signals are supported.
What network ports must be open?
Required ports include TCP 9736/9738/9744 and UDP 6900–6910, plus HTTPS 443.
How do I connect a captioning agency?
Agencies must be added to the encoder’s access code in iCap Admin.
Can one encoder run multiple Lexi instances?
No. Each encoder uses a single instance at a time.
Why does Lexi keep running when the encoder is off?
Jobs Mode allows Lexi to continue; Instance Mode is recommended to avoid this.
How long does a reboot take?
Typical reboot time is 1–2 minutes.
What if the encoder won’t boot?
The unit likely requires repair under an active support contract.
Can I install third‑party software?
No. Third‑party agents are not supported.
How do I reset encoder passwords?
Passwords are managed via the front LCD security menu or support.
Does HD492 support Telnet caption input?
Yes, alongside RS‑232 serial input.
How do I confirm audio is present?
Use the web UI audio meters and logs.
What is covered under Annual Support?
Software updates, capped repair costs, and RMA eligibility.
How do I download logs?
Logs are downloaded from the Logs section of the web interface.
Can HD492 output both 608 and 708 captions?
Yes, depending on configuration and firmware.
Why are captions delayed?
Delay is often due to audio issues, upstream processing, or downstream decoding.
Can HD492 be used for streaming workflows?
Yes, with appropriate downstream streaming infrastructure.
What happens during a power loss?
The encoder powers off immediately and resumes normal operation once power is restored.
How often should HD492 be rebooted?
Rebooting every few months is commonly recommended for stability.
Can multiple encoders share one access code?
No. Each encoder must have a unique access code.
How do I validate caption output?
Monitor directly from the encoder output using a compatible decoder.
Does HD492 support redundancy?
Redundancy is achieved by deploying multiple encoders, not within a single unit.
What causes frequent disconnections?
Network instability or firewall misconfiguration are the most common causes.
Can HD492 be remotely managed?
Yes, subject to network access and security policies.
How do I escalate HD492 issues?
Provide logs, serial number, firmware version, and timestamps to support.
