Frequently Asked Questions
What is the RS485 port used for?
Historically, the RS485 port was designed to allow SCADA monitoring software to read monitored data from the MN-NIO device using the Modbus RTU protocol. After Lua scripting support was added, however, this serial port gained much broader capabilities:
- It can still function as a serial port for upstream communication with host systems, though this role has largely been superseded by the MN-NIO's built-in Modbus TCP (Ethernet) capability;
- It can act as a master serial controller to interface with other RS485-enabled devices, enabling data acquisition and integration of third-party modules into the monitoring system.

Do you offer OEM/ODM customization? Can the MN-NIO be powered by -48V DC?
Yes. Telecom operators commonly require -48V DC power, and we have the engineering expertise to deliver custom OEM/ODM products, including -48V-powered variants.
Additionally, the standard MN-NIO includes a comprehensive set of digital and analog I/O channels. For cost-sensitive applications, unused I/O channels can be removed (trimmed) to reduce unit cost.
As a reference, we previously partnered with a company in Eastern Europe to deliver a customized MN-NIO variant designed exclusively for telecom carrier use: a DI-only model with SNMP Inform functionality, deployed to monitor a large fleet of equipment rooms and distribution frames.
What can the programmable logic (Lua scripting) feature accomplish?
The MN-NIO supports Lua-script-based logic programming in two primary modes:
- Local I/O control: Based on the status of the MN-NIO's own DI/AI channels, scripts perform local logic evaluation to directly control DO output states, or send alarms and notifications over the network (e.g., via SNMP traps, email alerts, or MQTT messages).
- Serial expansion and multi-module integration: Through the RS485 port, scripts can communicate with external modules, combining data from multiple devices to perform cross-module logic judgments and control actions. This mode also enables virtual DI/DO/AI/AO data points to be derived and reported upstream to central monitoring software or cloud-based IoT platforms.
Lua scripting transforms the MN-NIO from a simple I/O gateway into a flexible edge controller capable of autonomous decision-making at the device level, reducing latency and reliance on central servers.
