IMG-311DL-MNIndustrial M2M gateway with built-in LTE Cat-M1 and Cat-NB1 modem
IMG-311DL-MN is an M2M gateway for telemetry over narrowband cellular networks: the LTE Cat-M1/Cat-NB1 modem reaches 300/375 Kbps on Cat-M1 and 32/70 Kbps on Cat-NB1, with the antenna on a female SMA connector and a TCP, UDP, DHCP, SSH, DNS, SNMP V1/V2c, HTTPS and PPPoE stack.
The RS-232/422/485 serial port on DB9 works from 110 bps to 115.2 Kbps with configurable parity, stop bits and flow control; on board there are also one digital input and one digital output on a 3.5 mm jack. The DC input accepts 12-48 V on a 2-pole terminal block, with overload and reverse-polarity protection; the IP-30 enclosure mounts on DIN rail or panel, with optional 802.11g/n Wi-Fi.
