Shelf Manager ACB-VI
RS-232 Interfaces

R1.2, March 2018
4 RS-232 Interfaces
The ACB-VI provides two RS-232 interfaces. The first serial port is implemented using the
UART0, the second serial port is implemented using the UART1 on the ShMM-700R.
The first serial interface provides a full set of RS-232 signals, including modem control. In a
Schroff Shelf these signals are routed through the backplane connector to the SAP. The SAP
provides two 8-pin RJ45 modular receptacles for the serial interfaces of both Shelf Managers.
The second serial interface does not provide modem control signals. These signals are also
routed to the backplane connector but not used in the Schroff ATCA Shelves.
