Moxa Serial Device Servers are network devices designed to connect serial devices (like industrial equipment, machinery, sensors, and legacy systems) to Ethernet networks. These servers enable communication between serial-based devices (RS-232, RS-485, etc.) and modern IP-based networks, providing remote access, management, and monitoring over a TCP/IP network.
Here are some key details and features of Moxa Serial Device Servers:
1. Types of Moxa Serial Device Servers:
Single-Port and Multi-Port Serial Device Servers: Moxa offers both single-port and multi-port versions, allowing users to connect multiple serial devices to a single Ethernet network. Common configurations are 1, 2, 4, 8, or even 16 serial ports per device.
Ethernet to RS-232/RS-485/RS-422 Conversion: These servers provide conversion between Ethernet (TCP/IP) and various serial standards, such as RS-232, RS-485, and RS-422.
PoE (Power over Ethernet): Some models support Power over Ethernet, which simplifies installation by eliminating the need for separate power cables.
2. Key Features:
Remote Access to Serial Devices: With a serial device server, you can access and manage your serial devices over an Ethernet network or even the internet. This is especially useful for remote monitoring and maintenance of industrial systems.
Virtual COM Port (VCP): The device creates a virtual COM port on a computer, making serial devices appear as if they are directly connected to the computer’s serial port, even if they are physically located on a remote device server.
Multiple Communication Protocols: Moxa serial device servers typically support Modbus, DNP3, and other industrial protocols, allowing integration with control systems like SCADA (Supervisory Control and Data Acquisition).
Redundancy: Many Moxa serial servers support redundant power inputs or network redundancy protocols like Modbus/TCP or R-UDP to ensure continuous operation in critical environments.
Security: Features like SSL/TLS encryption, user authentication, and VPN support can be used to secure communication between the serial device and remote devices over the network.
DIN Rail Mountable: Like other Moxa industrial networking devices, many serial device servers are designed to be mounted on DIN rails for easy installation in control cabinets or enclosures.
Wide Operating Temperature Range: These devices are designed for use in harsh environments and can often operate in temperatures ranging from -40°C to 75°C or even higher.
3. Protocols and Communication Features:
TCP/IP and UDP: Supports standard IP communication protocols for network communication, such as TCP, UDP, and UDP broadcasting.
Modbus Gateway: Moxa\'s serial device servers often come with built-in Modbus TCP to Modbus RTU/ASCII gateways, allowing easy conversion between Modbus over Ethernet and Modbus over serial (RS-485/RS-232).
SNMP: Simple Network Management Protocol (SNMP) support allows for monitoring the health and performance of the serial device server remotely.
Serial-to-Ethernet Protocol Conversion: Converts serial communication protocols (RS-232, RS-485) into Ethernet-based protocols (TCP/IP).
4. Popular Moxa Serial Device Server Models:
NPort 5000 Series: Moxa’s NPort 5000 series is one of the most popular for industrial serial-to-Ethernet applications. It includes both single-port and multi-port models, and it is designed for a wide range of industrial and commercial applications.
NPort 5110 (1 port, RS-232)
NPort 5210 (1 port, RS-485/RS-422)
NPort 5230 (2 ports, RS-232)
NPort 5232 (2 ports, RS-485/RS-422)
NPort 5650 (16 ports)
NPort IA5000 Series: The IA5000 series is specifically designed for industrial applications, providing a high level of protection against electrical surges and noise interference. It\'s ideal for environments like factories, power plants, and transportation systems.
MiiNePort: The MiiNePort series is designed to embed serial-to-Ethernet conversion into devices like sensors, meters, and other equipment, allowing OEMs to integrate the device server into their products.
5. Applications of Moxa Serial Device Servers:
Industrial Automation: Remote monitoring and control of equipment like PLCs (Programmable Logic Controllers), HMIs (Human-Machine Interfaces), sensors, and actuators.
SCADA Systems: Integration of legacy devices into SCADA networks for real-time data acquisition and control.
Energy and Utilities: Monitoring and controlling equipment in power generation and distribution systems, such as substations, transformers, and meters.
Transportation: Linking signaling, control, and ticketing systems with centralized networked management.
Building Automation: Integrating HVAC, lighting, and access control systems into a centralized building management system.
Medical Equipment: Connecting diagnostic equipment, patient monitoring systems, and other devices to hospital networks.
