Wireless Broadband IP Modems for Wireless M2M
Serial IP Modem is a cellular modem working under cellular networks. Providing serial port (RS232 or RS485) for transparent transmission.
The industrial RS-232 and RS-232/422/485 GSM/GPRS/EDGE IP gateways are designed to transmit data transparently over 2G GSM/GPRS/EDGE/CDMA or 3G UMTS/HSDPA/HSUPA/HSPA+/EVDO or 4G LTE cellular networks. H820/H685/H900/H920’s can transmit data from both serial devices and Ethernet devices to a WAN interface, and come with private IP management software and VPN support for handling the IP address issue in cellular network structures. The products also come with a built-in relay output that can be configured to indicate the priority of events when notifying or warning engineers in the field. H820/H685/H900/H920’s redundant power inputs assure non-stop operation. Also offers wide temperature models which can withstand extreme temperature conditions.
