One box, one connection
Instead of exposing 20 devices to the internet, the GL-B100 holds a single outbound TLS connection. Everything behind it becomes an MQTT topic or an HTTP resource on your side.
Keeps working offline
Local rules keep printing, scanning and announcements running during an outage, then flush the event log once connectivity returns.
Retrofit what you already own
RS232 and RS485 ports, plus Modbus support, pull existing equipment into the same management plane as new Gobilink hardware.
