JetCon 1301 is a compact 1-port Fast Ethernet media converter designed as small as a cigarette box, making it an ideal model that would physically fit into a chassis with limited space, such as machinery control box and duct assembly room. It also supports switch forwarding mode with abnormal packet filtering and pure converter mode for extreme low latency requirement – fieldbus and EtherCAT, which needs invariant forwarding latency in 64~1522 bytes packet length. For easy maintenance and time-saving, JetCon 1301 features remote Link Loss Forwarding technology which provides remote link down signal forwarding, acknowledging link events occurred on each end of JetCon 1301. To activate forwarding mode and LLF functions, simply adjust DIP switch and reset the converter and the reconfiguration will be applied.
