BarnMini-05 offers a compact way to convert an RS422/RS485 serial data, 4 x GPI and 4 x GPO to Ethernet. The unit can serve as an intelligent bridge between many third-party devices, for example transferring an RS422 signal or tally between two locations, or it can control an external optical changeover switch such as BarnMini-06 in a redundancy setup. Triggers are easily set, and the module works well in conjunction with any BarnOne frames. BarnStudio, Barnfind’s control software, can be used to configure and monitor BarnMini-05.
