Having issues with Serial Connections on Motorola MVME162P4 VME Embedded Controller? Read our step-by-step SMT maintenance solution below. If you require replacement feeders, nozzles, or sensors, contact SMTBOX for OEM-compatible parts.
The MVME162P4 uses a Zilog Z85230 serial port controller to implement the two serial communications interfaces. Each interface supports:
1. CTS, DCD, RTS, and DTR control signals
2. TXD and RXD transmit/receive data signals
3. TXC and RXC synchronous clock signals
The Z85230 supports synchronous (SDLC/HDLC) and asynchronous protocols. The MVME162P4 hardware supports asynchronous serial baud rates of 110b/s to 38.4Kb/s.
For additional information on the MVME162P4 serial communications interface, refer to the Z85230 Serial Communications Controller Product Brief listed under Manufacturer’s Documents in the Related Documentation appendix. For additional information on the EIA-232-D interface, refer to the EIA-232-D Standard.
The following figures illustrate the signal relationships and signal connections in the various serial configurations available for ports A and B.
