Product Introduction
Plant upgrades usually mean a painful choice: rip out all legacy controllers or leave your network fragmented. The YOKOGAWA AVR10D-Q22020 kills that dilemma. It acts as the exact bridge between modern CENTUM VP Human Interface Stations (HISes) running on 100 Mbps Vnet/IP and older CENTUM CS 3000 or CS 1000 stations still talking on 10 Mbps V-Net or VL-Net.
You get dual-redundant BNC connections for the legacy side and a standard RJ45 for the modern side. Honestly, the real value here is avoiding a massive, multi-million dollar control system overhaul. It lets you modernize the operator interfaces while keeping the field-proven legacy controllers exactly where they are. Just remember, connecting to CS 3000 systems requires the LHS4450 Multiple Project Connection Package.

Troubleshooting Quick Reference
| Symptom | Probable Cause | Relevancy | Quick Check | Fix |
|---|---|---|---|---|
| Vnet/IP Link Down | Bad Ethernet Cable | 85% | Check RJ45 link lights | Replace with CAT5e+ cable |
| V-Net Comm Loss | Coax Termination | 80% | Check BNC T-connector | Verify 50-ohm terminator |
| Intermittent Drops | Ground Loop | 70% | Measure ground potential | Check M4 ground terminal |
| Config Error | Missing Software | 90% | Verify LHS4450 package | Install required Connection Builder |
| Module Dead | Power Supply | 85% | Measure 24VDC at M4 | Check power supply fuse |
Application Scenarios & Pain Points
- Phased DCS Upgrades: Migrating a 20-year-old plant to CENTUM VP without ripping out working CS 3000 controllers. The router bridges the gap during the 5-year transition.
- VL-Net Domain Expansion: Connecting remote CENTUM CS 1000 stations located in different physical domains back to the main Vnet/IP control room.
- Legacy HIS Integration: Keeping older operator stations functional while adding new high-resolution graphics on modern Vnet/IP workstations.

Compatible Replacement Models
- ✅ Drop-in Replacement: YOKOGAWA AVR10D-Q22020. Same revision, same BNC/RJ45 layout. No configuration changes.
- ⚠️ Software Compatible: YOKOGAWA AVR10D-A22020. Same platform family. Verify V-Net/VL-Net configuration matches your legacy network topology. Requires CENTUM VP network re-download.
- ❌ Hardware Incompatible: . This is a single V-Net router with different power module configuration. Different pinout, different redundancy scheme. Do not substitute.
