This module is used to connect additional discrete RS232 serial communication ports to the SSE-MAESTRO M2000 or RTU12. One of the RS232 ports of the CPU gets wired to this module, which will multiplex the RS232 communication. This module can only be used where the CPU communicates as master to other Intelligent Electronic Devices (IED’s).
The module is connected to the SSE-MAESTRO via a 26-Way ribbon Bus connecter..
