Serial Connections
The MVME162P2 uses two Zilog Z85230 serial port controllers to
implement the four serial communications interfaces. Each interface
supports:
❏
CTS, DCD, RTS, and DTR control signals
❏
TXD and RXD transmit/receive data signals
Because the serial clocks are omitted in the MVME162P2 implementation,
serial communications are strictly asynchronous. The Z85230s are
interfaced as DTE (data terminal equipment) with EIA-232-D signal
levels. The serial ports are routed to four RJ-45 connectors on the front
panel. The MVME162P2 hardware supports asynchronous serial baud
rates of 110b/s to 38.4Kb/s.
For the pin assignments of the RJ-45 connectors on the front panel, refer
to Chapter 5, Pin Assignments. For additional information on the
MVME162P2 serial communications interface, refer to the Z85230 Serial
Communications Controller Product Brief listed under Manufacturer’s
Documents in Appendix E, Related Documentation. For additional
information on the EIA-232-D interface, refer to the EIA-232-D Standard.
