This module is used to connect additional discrete RS232 serial
communication ports to the SSE-RTU11. One of the RS232 ports of the
RTU gets wired to this module, which will multiplex the RS232
communication. This module can only be used where the RTU
communicates as master to other Intelligent Electronic Devices (IED’s).
