交流故障斷路器當交流故障中斷啟用且PCC接收到交流故障信號,7級中斷發送至MC68030。交流電源故障可以通過軟件啟用/禁用中斷。交流電源故障當請求時,中斷器提供狀態/ID向量。串行端口接口MVME147使用兩個Z8530串行通信控制器(SCC)實現四個串行端口的設備。5 MHz時鐘用于生成波特率時鐘,串行端口支持標準波特率(110到19200)。串行端口4也支持同步操作模式。

1C31169G02輸出模塊MVME147上的四個串行端口功能不同因為P2連接器上的引腳數量有限。電視連續劇端口1是最小功能異步端口。它使用RXD、CT、,TXD和RTS。串行端口2和3是全功能異步端口端口。他們使用RXD、CT、DCD、TXD、RTS和DTR。串行端口4是一個全功能異步或同步端口。它使用RXD,CT、DCD、TXD、RTS和DTR。它還與同步時鐘信號線。

所有四個串行端口使用EIA-232-D驅動器和接收器,位于MVME147和所有信號線路由至P2。這個配置標頭位于MVME147和MVME712。外部輸入/輸出轉換板,如MVME712必須用于將P2引腳轉換為行業標準連接器。MVME712上的標題為以下各項提供了跳線可選選項:每個EIA-232-D接口配置為連接到DTE或DCE。有關SCCs的更多信息,請參閱Zilog文獻在相關文件中列出。MVME147-010上未使用以太網接口。MVME147使用AM79C90局域網控制器用于以太網(LANCE)和AM7992串行接口適配器(SIA)實現以太網收發器接口。平衡的來自AM7992的差分收發器信號線是耦合的通過車載變壓器連接至通向P2的信號線連接器并最終連接到MVME712過渡板,其中它們連接到行業標準DB-15連接器。

AC Fail Interrupter

When the AC Fail interrupt is enabled and the PCC receives an AC

Fail signal, a Level 7 interrupt is sent to the MC68030. The AC Fail

interrupt can be enabled/disabled by software. The AC Fail

interrupter provides a status/ID vector when requested.

Serial Port Interface

The MVME147 uses two Z8530 Serial Communications Controller

(SCC) devices to implement the four serial ports. A 5 MHz clock is

used to generate the baud rate clock and the serial ports support the

standard baud rates (110 through 19,200). Serial port 4 also

supports synchronous modes of operation.

The four serial ports on the MVME147 are different functionally

because of the limited number of pins on the P2 connector. Serial

port 1 is a minimum function asynchronous port. It uses RXD, CTS,

TXD, and RTS. Serial ports 2 and 3 are full function asynchronous

ports. They use RXD, CTS, DCD, TXD, RTS, and DTR. Serial port 4

is a full function asynchronous or synchronous port. It uses RXD,

CTS, DCD, TXD, RTS, and DTR. It also interfaces to the

synchronous clock signal lines.

All four serial ports use EIA-232-D drivers and receivers located on

the MVME147 and all the signal lines are routed to P2. The

configuration headers are located on the MVME147 and the

MVME712. An external I/O transition board such as the MVME712

must be used to convert the P2 pin out to industry standard

connectors.

Headers on the MVME712 provide jumper selectable options for

each EIA-232-D interface to be configured to connect to DTE or

DCE.

For additional information on the SCCs, refer to the Zilog literature

listed in Related Documents. The Ethernet interface is not used on the MVME147-010.

The MVME147 uses the AM79C90 Local Area Network Controller

for Ethernet (LANCE) and the AM7992 Serial Interface Adapter

(SIA) to implement the Ethernet transceiver interface. The balanced

differential transceiver signal lines from the AM7992 are coupled

via an onboard transformer to signal lines that go to the P2

connector and eventually to the MVME712 transition board, where

they are connected to an industry standard DB-15 connector.
