Your Cooling Equipment Has the Data. But It Cannot Get Out.
Serial interfaces hold operational data inside equipment while dashboards, alerts, analytics, and AI workflows expect IP data.
Serial equipment, IP systems
CDUs, chillers, and pumps output data through RS232/RS485 while monitoring systems need IP streams.
Manual collection is slow
Physical rounds are too slow for high-density GPU clusters where thermal anomalies need fast escalation.
Replacement is the wrong fix
Working cooling assets should not be replaced only to gain network visibility.
No history, no trends
Without continuous cloud data, teams lose the dataset needed for reporting and optimization.
YenGear Provides the Hardware and Cloud Layer for Intelligent Cooling Management
DTUs and I/O modules connect existing field equipment, while YenGear IoT Cloud supports monitoring, alerts, remote control workflows, and data export.
Six Capabilities That Enable Intelligent Cooling Management
The data, I/O, network, cloud, and coexistence capabilities YenGear provides.
Serial-to-network conversion
Y204-R/Y208-R DTUs convert RS232/RS485 to Modbus TCP, MQTT, and HTTP.
I/O monitoring and control
Y301/Y311 I/O modules connect sensors and actuators (DI/DO/AI/AO). Digital outputs drive relays, valves, and alarms.
Ethernet data transmission
DTUs connect to existing Ethernet infrastructure. Y208-R adds dual uplinks (LAN1/LAN2) for automatic failover.
Dual-Socket Architecture
Each DTU port runs Socket A and B concurrently. SCADA and YenGear IoT Cloud receive data simultaneously.
Remote Control & AI Optimizatio
IoT Cloud supports manual commands, threshold-based automation, and AI-driven parameter tuning.
Unified Monitoring & Export
Single dashboard across all sites. Alerts, historical trends, and API-based data export.

Costs
DTUs solved the connectivity problem, I/O modules gave us valve and pump control, and the cloud handled monitoring and AI optimization — at a fraction of the replacement cost. The first time the AI adjusted pump speeds before anyone noticed a thermal spike, we knew this was working.

Security & Reliability
Because Cooling Management Demands Enterprise-Grade Trust
Enterprise Network Integration
Connects to your existing Ethernet network, including VLAN-segmented environments. No wireless attack surface or signal interference.
Dual-Link Redundancy
Y208-R supports dual Ethernet uplinks (LAN1/LAN2) with automatic failover. Monitoring and control continue if one path fails.
End-to-End Encryption
YenGear IoT Cloud uses TLS 1.3 for communications and AES-256 for data at rest. All control commands encrypted in transit.
Immutable Audit Trail
YenGear IoT Cloud logs every data point, configuration change, and control action with timestamps. Full auditability for compliance and incident investigation.
Hardware Reliability
−40°C to +85°C operating range (I/O modules). Hardware and software watchdogs recover from transient failures automatically.
Coexistence with Existing Systems
Dual Socket keeps your existing SCADA on Socket A. Cloud monitoring and control run on Socket B — no disruption to proven infrastructure.
Frequently Asked Questions
Direct raw FAQ section: accordion-style question and answer content.
Why choose Ethernet DTU over wireless solutions?
Data centers already operate managed Ethernet networks. DTUs use that infrastructure for deterministic connectivity, security policy alignment, and operational visibility.
Can YenGear hardware be provisioned in a live data center?
Yes. DTUs connect to existing serial ports and I/O modules connect to signal points without replacing working cooling equipment.
How does this integrate with existing SCADA?
Dual-socket data paths can keep current SCADA/control access active while YenGear IoT Cloud receives a parallel data stream.
What equipment can be connected?
Cooling equipment with RS232 or RS485 ports, plus sensors, relays, alarms, valves, and pump signals through Y301/Y311 I/O modules.
Is YenGear a full BMS or DCIM platform?
No. YenGear provides the DTU, I/O, and cloud monitoring/control layer that can integrate into broader ecosystems.
