BENTLY 125720-01 3500/32通道繼電器模塊
啟動(dòng)程序概述下表列出了您之前需要做的事情你可以使用這個(gè)板，在哪里可以找到你需要的信息執行每個(gè)步驟。一定要閱讀這整章，并閱讀所有內容開(kāi)始前的注意事項。硬件準備選擇所需配置并確保對于MVME177，可能需要進(jìn)行某些選項修改安裝前。MVME177為以下各項提供軟件控制：大多數選項。有些選項無(wú)法在軟件中完成，因此由標題上的跳線(xiàn)完成。

? SRAM備用電源選擇標題（J2）（可選）? 系統控制器標題（J6）? 熱敏引腳（J7）? EPROM/閃存配置跳線(xiàn)（J8）? 串行端口4時(shí)鐘配置選擇標頭（J9和J10）
請參閱表2-2，為每個(gè)標頭配置跳線(xiàn)設置。標頭J1上的通用可讀跳線(xiàn)可以讀取為輸入/輸出控制
VMEchip2 LCSR中的寄存器3（位于$FFF40088，位0-7）（參見(jiàn)第4章，VMEchip2）。跳線(xiàn)斷開(kāi)時(shí)，位值讀取為1，讀取為0當跳線(xiàn)接通時(shí)。2.MVME177上，移除了板ID和位的引腳7和8（位3）保留值。
Overview of Start-up Procedure
The following list identifies the things you will need to do before
you can use this board, and where to find the information you need
to perform each step. Be sure to read this entire chapter and read all
Caution notes before beginning. Hardware Preparation
To select the desired configuration and ensure proper operation of
the MVME177, certain option modifications may be necessary
before installation. The MVME177 provides software control for
most of these options. Some options cannot be done in software, so
are done by jumpers on headers. Most other modifications are done
by setting bits in control registers after the MVME177 has been
installed in a system. (The MVME177 registers are described in
Chapter 4, and/or in the Single Board Computers Programmer's
Reference Guide as listed in Related Documentation in Chapter 1).
The location of switches, jumper headers, connectors, and LED
indicators on the MVME177 is illustrated in Figure 2-1.
The MVME177 has been factory tested and is shipped with the
factory jumper settings described in the following sections. The
MVME177 operates with its required and factory-installed Debug
Monitor, MVME177Bug (177Bug), with these factory jumper
settings.
Settings can be made for:
? General purpose readable jumpers on header (J1)
? SRAM backup power source select header (J2) (optional)
? System controller header (J6)
? Thermal sensing pins (J7)
? EPROM/Flash configuration jumper (J8)
? Serial port 4 clock configuration select headers (J9 and J10)
Refer to Table 2-2 to configure the jumper settings for each headerThe general purpose readable jumpers on header J1 can be read as I/O control
register 3 (at $FFF40088, bits 0-7) in the VMEchip2 LCSR (see Chapter 4,
VMEchip2). The bit values are read as a 1 when the jumper is off, and as a 0
when the jumper is on.
2. On the MVME177, pins 7 and 8 (bit 3) are removed for board ID and the bit
value is reserved.
