µPORT

µPORT was designed as a small and cost-effective modem for remote data transmission from electricity meters and different types of controllers and devices equipped with RS232 or RS485 serial interfaces. The comander µPORT range of devices can use various technologies ranging from 2G to LTE. In addition, optional features such as a potential-free input or PWM 10 V external device control line make them ideal for applications in the energy and industrial sectors.

Specifications

Key characteristics of the comander µPORT device include:

• Small dimensions (height × width × depth): 85 × 96 × 34 mm
• High protection rating: IP53
• Power supply voltage: 100 to 240 V AC
• Broad range of operating temperatures: -25 to +60°C
• Sealed connector cover to protect against unauthorized access
• Clear status and signal level indications with LEDs on the front panel
• Power consumption: 5 W (average)
• DIN rail mounting capability

Radio communications

The broad range of comander µPORT modems can use GSM radio communications modules that support the following technologies:

• Penta-Band LTE: 800/900/1800/2100/2600 MHz, FDD Band (20, 8, 3, 7, 1)
• Tri-Band UMTS/HSPA (WCDMA): 900/1800/2100 MHz, FDD Band (8, 3, 1)
• Dual-Band GSM/GPRS/EDGE: 900/1800 MHz

Functionality

µPORT modems support a range of useful features:

• Support of TCP/IP, UDP/IP, ICMP, Telnet
• Transparent handling of data from the serial interface
• Powerful feature set to support electricity meters (including time synchronization and automatic protocol recognition)
• Real-time clock with battery backup; clock synchronization via NTP or from the GSM
• Remote and local hardware and software restart feature
• Proprietary algorithms to monitor key quality metrics of the entire communication channel in TCP/IP mode and GSM mode: Link Control and GPRS Control
• Device configuration access security controls
• Internal event log
• Built-in IP address filter to support whitelisting and blacklisting for inbound connections
• Optional ability to send alerts when power is lost/restored (built-in battery or supercapacitor)
• Compliance with industry standards in terms of technical and security specifications

Equipment

As standard, comander µPORT modems come with the following features:

• RS485 or RS232 serial interface (terminal block)
• mini USB 2.0 configuration port
• SMA antenna port
• SIM card slot (2FF USIM)

Additional features include:
