JA-121T RS-485 bus interface
The JA-121T module is a universal adapter to RS-485 for other systems. It enables connection of the JABLOTRON 100+ system bus to an RS-485 serial line and vice versa.
JA-121T RS-485 bus interface
An application can be e.g. for the connection of a Smart Home system. It contains galvanically separated circuits for 4 kV. Data are sent in the case of a status change or on request. In the passive mode all data are only sent on request. The module is addressable and it occupies one position in the system
