Inside the router works an ARM Cortex A7 with 528 MHz clock rate, pre-installed 128 MB DDR3 RAM and 128 MB flash memory. Five RJ45 10/100 Base-T interfaces are available as network interfaces, which can be configured in a combination of 1x WAN and 4x LAN or 2x WAN and 3x LAN. IPsec, OpenVPN, GRE, L2TP, PPTP, DMVPN, SNMP, TCP, UDP, RIP are just a few of the supported network protocols and frameworks. At serial interfaces the UR55 offers two RS-232, two RS-485 or one RS-232 and one RS-485 with a baud rate from 300 bps up to 230400 bps. The UR55 supports the transparent mode as TCP Client/Server or can be used as Modbus Gateway (Modbus RTU on Modbus TCP). For the direct connection of switches, sensors, etc., two digital inputs and two digital outputs are available. Further optional expansion stages provide WLAN functionality and GPS. The voltage input is designed from 9 to 48 VDC and the router consumes a maximum of 4.3 watts of power. The UR55 operates reliably in a temperature range from -40 °C to 70 °C. The UR55 is designed for a maximum power consumption of 4.3 watts. The UR55 can be easily configured via the Web GUI. Remote maintenance can also be performed via SNMP or the cloud-based device hub. Simple deployment and comprehensive remote device management make the UR55 suitable for many IoT/M2M applications. ▪ ds
