Serial data remains isolated
Equipment data exposed only through serial interfaces is not directly available to IP-based monitoring and reporting systems.

Cooling Equipment Status Monitoring and Interlock Control
Monitor the status of cooling units, pumps, fans, valves and power-distribution equipment, and integrate with existing BMS, PLC or monitoring platforms. Critical protections affecting equipment safety and business continuity should be executed by an approved and tested local system.

Cooling Data Is Often Isolated on Serial Interfaces
Monitoring systems require network data
CDUs, chillers and pumps may output data through RS232 or RS485 while supervisory systems require an IP connection.
Manual checks provide limited coverage
Periodic equipment rounds do not provide a continuous record of operating conditions.
Existing equipment remains in service
A gateway can add network connectivity to compatible cooling equipment without replacing the equipment itself.
Historical analysis requires consistent data
Continuous data collection supports trend review, reporting and operating analysis.
Hardware and Cloud Tools for Cooling Monitoring
DTUs and I/O modules connect existing field equipment, while YenGear IoT Cloud supports monitoring, alerts, remote control workflows, and data export.
Connect Serial Cooling Equipment to IP Networks
Connect serial devices and I/O points, configure protocol mapping, stream data, then monitor and control from the cloud.
Connect
DTUs connect to RS232/RS485 cooling equipment; I/O modules connect sensors, relays, valves, pumps, and alarms.
Configure
Map serial data, I/O points, and cloud connection settings through web configuration workflows.
Stream
Cooling data flows to cloud and SCADA systems while control commands reach I/O outputs.
Operate
Use dashboards, alerts, histories, reports, and data exports to improve cooling operations.
Cooling Connectivity and Monitoring Functions
Connect serial data and I/O points while retaining existing SCADA access where required.
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 commands and operating rules
IoT Cloud supports manual commands and threshold-based automation for configured equipment points.
Monitoring and data export
Dashboards provide alerts and historical trends, with API-based data export for compatible integrations.
MiniLink DTU for Cooling Data Connectivity

Dual-socket configurations can maintain an existing SCADA connection while sending a separate data stream to another system.
Frequently Asked Questions
Common integration questions for data center operators and system integrators.
Should we use Ethernet or wireless for cooling equipment?
Ethernet is often evaluated when a managed network and suitable cabling are already available. Wireless may be useful where cabling is difficult. The choice depends on the equipment interface, network policy, response requirements and site survey.
Can existing cooling equipment be connected?
Existing equipment may be connected through compatible RS232, RS485 or discrete I/O interfaces without replacing the equipment. Confirm the protocol, register map, electrical isolation, access window and change-control requirements before installation.
What information is needed for SCADA integration?
Provide the equipment interface, protocol, point list, addressing, read/write permissions, update frequency, alarm ownership and network rules. The final data path and any parallel access depend on the equipment and integration review.
What equipment and signals can be connected?
Compatible cooling equipment, sensors, relays, alarms, valves and pump signals can be evaluated through serial interfaces or Y301/Y311 I/O modules. Voltage, signal type, protocol and control responsibility must be confirmed for each point.
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.
