Gateway
Small WLAN gateway for serial data
Serial data that is recorded at a specific position in a system or building often has to be routed to a central control system via long data lines. A wireless link would be a more elegant and efficient solution here. Acceed presents the Aport-213, a new pocket-sized gateway specially developed for this purpose. The Aport-213 is available from the independent German distributor Acceed.
The networking of sensors and other data acquisition units under the buzzwords M2M, ZigBee or Industry 4.0 is the core task in communication between many devices within a system with or without central control. In the Internet of Things (IoT), a large number of specialized units such as sensors, actuators and controllers are used in building management as well as in industrial plants, large-scale warehouses or residential units. The first step is the transmission of separately recorded serial data from sensors and other units. This is where the new Aport-213 comes into its own as a serial WLAN gateway.
The Aport-213 has a serial interface that is designed as a conventional DB9 connection. The desired protocol (RS-232 / 422 / 485) can be set using a DIP switch. The gateway transparently forwards the fed-in data to the network, where it can be used and processed by existing software.
The supported protocols include TCP, UDP, ICMP, IGMP, IPv4, DHCP, ARP, DNS, SMTP and SNTP. Configuration is possible via web browser or serial console, a Windows utility is available free of charge.
During operation, a wide temperature range of 0 to 70 °C is permitted, which also supports the installation of the small device in housings and ducts. Intelligent energy management minimizes power consumption to 180 mA (at 12 VDC) during data transfer and further reduces power consumption to a minimum during periods of inactivity. This makes the Aport-213 particularly suitable for use with sensors for environmental monitoring, for example in greenhouses, access control, fill level monitoring and many other manufacturing and automation applications.
LEDs provide information on operational readiness, status and use of the COM interfaces for data transfer and console connection. Power can be supplied in the range from 9 to 48 V DC either via the terminal block or a micro USB socket. The power supply unit and the mounting set for the top-hat rail are available as suitable accessories.
