About
AF-GSM300-4G Smart Gateway
● It supports data acquisition of the serial port MODBUS RTU protocol and communicates with the Acrel server through the Acrel platform protocol.
● It supports for data acquisition of up to 30 MODBUS RTU devices.
● It supports the acquisition of 5 register address fields for each MODBUS device, with each register address range not exceeding 64.
● It supports triggering alarms by presetting alarm addresses and alarm values for each MODBUS address range. There are currently up to 14 alarm addresses for each address field.
● It supports server MODBUS or LORA unvarnished transmission communication.
● It supports to connect the data center by fixed IP and dynamic domain name resolution.
General
AF-GSM is a new 4G remote wireless data acquisition device launched by Acrel Electric. By adopting embedded design, it is embedded TCP/IP protocol stack, as well as powerful microprocessor chip and built-in watchdog, therefore, it has reliable and stable performance.
Operating and display
1. LINK: two seconds of flashing indicates it is initializing the wireless module; One second of flashing indicates it is connecting the server; Normally on indicates it has been connected to the server.
2. - PSSI: 1 second of flashing signal indicates the value is less than 50%; 0.5 second of flashing signal indicates the value is greater than 50%; Normally on signal indicates the value is greater than 80%.
3. - COMM: it flashes once when there is a pack of data interacting with the download device.
4. - NET: it flashes when there is network data transmission.
The interface on one side of AF-GSM300/400 is shown in Figure 1:
