Functional Description http://www.mcg.mot.com/literature 1-19 1 I/O Interfaces The MVME162FX Embedded Controller provides onboard I/O for many system applications. The I/O functions include serial ports, Industry Pack interfaces, optional LAN Ethernet transceiver interface, and an optional SCSI mass storage interface. Serial Communications Interface The controller uses a Zilog Z85230 serial communications controller to implement the two serial communications interfaces. Each interface supports CTS, DCD, RTS, and DTR control signals; as well as the TxD and RxD transmit/receive data signals, and TxC/RxC synchronous clock signals. The Z85230 supports synchronous (SDLC/HDLC) and asynchronous protocols. The controller’s hardware supports asynchronous serial baud rates of 110b/s to 38.4Kb/s. The Z85230 supplies an interrupt vector during interrupt acknowledge cycles. The vector is modified based upon the interrupt source within the Z85230. Interrupt request levels are programmed via the MC2 chip. One MC2 chip can handle up to four Z85230 chips. Refer to the Z85230 data sheet shown in Appendix F, and to the MC2 chip Programming Model in the MVME162FX Embedded Controller Programmer’s Reference Guide, for information. MVME162FX Serial Port 1 The A port of the Z85230 is interfaced as DCE (data circuit-terminating equipment) with the EIA-232-D interface and is routed to: ❏ The DB-25 connector marked SERIAL PORT 1/CONSOLE on the front panel of the controller. SERIAL PORT 1/CONSOLE is an EIA-232-D DCE port. NOTE: This port can be connected to the TX and RX clocks which may be present on the DB-25 connector. These connections are made via jumper header J11 on the controller. Note that the TxC and RxC clock lines are not available on the MVME712x transition modules. 1-20 Computer Group Literature Center Web Site Board Level Hardware Description 1 ❏ One of the following output connectors on the MVME712x transition module: MVME712M: The DB-25 connector marked SERIAL PORT 2 on the front panel. SERIAL PORT 2 can be configured as an EIA-232- D DTE or DCE port, via jumper headers J16 and J17. MVME712A or MVME712-12: The DB-9 connector marked SERIAL PORT 2 on the front panel. SERIAL PORT 2 is hardwired as an EIA-232-D DTE port. MVME712AM or MVME712-13: The DB-9 connector marked SERIAL PORT 2 OR the RJ-11 jack on the front panel. SERIAL PORT 2 is hardwired as EIA-232-D DTE; the RJ-11 jack utilizes the built-in modem. Setting the jumper headers J16 and J17 on the MVME712AM/-13 configures the output as EIA-232-D DTE at SERIAL PORT 2 or as a modem at the RJ-11 jack. Figure 2-3 (sheets 1 and 2) in Chapter 2 illustrates the two configurations available for Port A when the controller is used with an MVME712M. Figure 2-5 (sheets 1 and 2) shows the two configurations available for Port A when the controller is used with an MVME712A/AM/-12/-13. MVME162FX Serial Port 2 The configuration of B port of the Z85230 is determined via a Serial Interface Module (SIMM) which is installed at connector J10 on the controller. There are five SIMMS available: SIMM05 - DTE with EIA-232-D interface SIMM06 - DCE with EIA-232-D interface SIMM07 - DTE with EIA-530 interface SIMM08 - DCE with EIA-530 interface SIMM09 - EIA-485 interface, or DCE or DTE with EIA-422 interface Port B is routed, via the SIMM, to: ❏ The DB-25 connector marked SERIAL PORT 2 on the front panel of the MVME162FX controller. SERIAL PORT 2 will be an EIA232-D DCE or DTE port, or an EIA-530 DCE or DTE port, or an EIA-485 port, or an EIA-422 DCE or DTE port, depending upon which module is installed. Functional Description http://www.mcg.mot.com/literature 1-21 1 Note Port B is factory configured for asynchronous communication. For synchronous communication, this port can be connected to the TX and RX clock signals which may be present on the DB-25 connector. These connections are made via jumper header J12 on the controller. The TxC and RxC clock lines are available at the MVME712M SERIAL PORT 4 via header J15 on that board, but are not available on the other MVME712x transition modules. ❏ One of the following output connectors on the MVME712x transition module: MVME712M: The DB-25 connector marked SERIAL PORT 4 on the front panel. SERIAL PORT 4 can be configured as an EIA-232- D DTE or DCE port, via the jumper headers J18 and J19 on the MVME712M. MVME712A, AM, -12, or -13: The DB-9 connector marked SERIAL PORT 4 on the front panel. SERIAL PORT 4 is hard-wired as an EIA-232-D DTE port. Figure 2-3 (sheets 3 through 6) in Chapter 2 shows the four configurations available for Port B when the MVME162FX Embedded Controller is used with an MVME712M. Note that the port configurations shown in Figure 2-3, sheets 5 and 6 are not recommended for synchronous applications
