PXI-6233
將PXI兼容產(chǎn)品與標(biāo)準(zhǔn)CompactPCI產(chǎn)品配合使用是PXI規(guī)范1.0版提供的一項(xiàng)重要功能。如果在標(biāo)準(zhǔn)CompactPCI機(jī)箱中使用與PXI兼容的插件設(shè)備,則無法使用PXI特定功能,但仍可以使用基本插件設(shè)備功能。例如,6711/6713設(shè)備上的PXI觸發(fā)總線在PXI機(jī)箱中可用,但在CompactPCI機(jī)箱中不可用。CompactPCI規(guī)范允許供應(yīng)商開發(fā)與CompactPCI總線上的基本PCI接口共存的子總線。不保證具有不同子總線的CompactPCI設(shè)備之間的兼容操作,也不保證具有子總線的CompactPCI設(shè)備與PXI之間的兼容操作。CompactPCI的標(biāo)準(zhǔn)實(shí)現(xiàn)不包括這些子總線。您的6711/6713設(shè)備將在任何符合PICMG CompactPCI 2.0 R2.1文檔的標(biāo)準(zhǔn)CompactPCI機(jī)箱中工作。PXI特定功能、RTSI總線觸發(fā)器、RTSI時(shí)鐘和串行通信在CompactPCI總線的J2連接器上實(shí)現(xiàn)。表1-1列出了PXI-6711/6713使用的J2引腳,該引腳與任何具有不驅(qū)動(dòng)這些線路的子總線的CompactPCI機(jī)箱兼容。即使子總線能夠驅(qū)動(dòng)這些線路,只要子總線上的這些引腳在默認(rèn)情況下處于禁用狀態(tài)且從未啟用,6711/6713仍然兼容。如果這些線路由子總線驅(qū)動(dòng),可能會(huì)導(dǎo)致?lián)p壞。



Using PXI-compatible products with standard CompactPCI products is an important feature provided by the PXI Specification, revision 1.0. If you use a PXI-compatible plug-in device in a standard CompactPCI chassis, you will be unable to use PXI-specific functions, but you can still use the basic plug-in device functions. For example, the PXI trigger bus on your 6711/6713 device is available in a PXI chassis but not in a CompactPCI chassis. The CompactPCI specification permits vendors to develop sub-buses that coexist with the basic PCI interface on the CompactPCI bus. Compatible operation is not guaranteed between CompactPCI devices with different sub-buses nor between CompactPCI devices with sub-buses and PXI. The standard implementation for CompactPCI does not include these sub-buses. Your 6711/6713 device will work in any standard CompactPCI chassis adhering to the PICMG CompactPCI 2.0 R2.1 document. PXI-specific features, RTSI bus trigger, RTSI Clock, and Serial Communication, are implemented on the J2 connector of the CompactPCI bus. Table 1-1 lists the J2 pins used by your PXI-6711/6713, which is compatible with any CompactPCI chassis with a sub-bus that does not drive these lines. Even if the sub-bus is capable of driving these lines, the 6711/6713 is still compatible as long as those pins on the sub-bus are disabled by default and are never enabled. Damage can result if these lines are driven by the sub-bus.
