The MVME162LX Embedded Controller uses two Zilog Z85230 serial
port controllers to implement the four serial communications interfaces.
Each interface supports CTS, DCD, RTS, and DTR control signals as well
as the TXD and RXD transmit/receive data signals. Because the serial
clocks are omitted in the MVME162LX implementation, serial
communications are strictly asynchronous. The Z85230 is interfaced as
DTE (data terminal equipment) with EIA-232-D signal levels.
Figure D-1 shows the connections between the Z85230 and the RJ45
connectors.
