VMIVME-7750上的IDE接口支持ATA-33、ATA-66和ATA-100驅(qū)動(dòng)器，并根據(jù)使用的驅(qū)動(dòng)器類型自動(dòng)確定正確的操作模式。為了在ATA-100模式下正常工作，必須使用特殊的80芯電纜，而不是標(biāo)準(zhǔn)的40芯電纜。該電纜通常可從ATA-100驅(qū)動(dòng)器制造商處獲得。以太網(wǎng)控制器雙網(wǎng)絡(luò)功能由外部Intel 82559ER以太網(wǎng)控制器和Intel ICH2芯片內(nèi)部的MAC提供。兩個(gè)以太網(wǎng)控制器都是基于PCI的，并且是軟件可配置的。VMIVME-7750支持雙10BaseT和100BaseTx以太網(wǎng)。10BaseT基于10BaseT標(biāo)準(zhǔn)的網(wǎng)絡(luò)使用非屏蔽雙絞線，通過允許使用現(xiàn)有電話線路和連接器，為網(wǎng)絡(luò)提供了經(jīng)濟(jì)的解決方案。RJ-45連接器用于10BaseT標(biāo)準(zhǔn)。10BaseT的最大長度為100米。100BaseTxVMIVME-7750還支持100BaseTx以太網(wǎng)。基于100BaseTx標(biāo)準(zhǔn)的網(wǎng)絡(luò)使用非屏蔽雙絞線和RJ-45連接器。100BaseTx的最大長度為100米。
The IDE interface on the VMIVME-7750
supports ATA-33, ATA-66 and ATA-100 drives and automatically determines the
proper operating mode based on the type of drive used. In order to properly function
in the ATA-100 mode, a special 80 conductor cable must be used instead of the
standard 40 conductor cable. This cable is typically available from the ATA-100 drive
manufacturer.Ethernet Controllers
The dual network capability is provided by an external Intel 82559ER Ethernet
Controller and a MAC internal to the Intel ICH2 chip. Both Ethernet controllers are
PCI-based and are software configurable. The VMIVME-7750 supports dual 10BaseT
and 100BaseTx Ethernet.
10BaseT
A network based on the 10BaseT standard uses unshielded twisted-pair cables,
providing an economical solution to networking by allowing the use of existing
telephone wiring and connectors. The RJ-45 connector is used with the 10BaseT
standard. 10BaseT has a maximum length of 100 meters.
100BaseTx
The VMIVME-7750 also supports the 100BaseTx Ethernet. A network based on a
100BaseTx standard uses unshielded twisted-pair cables and a RJ-45 connector. The
100BaseTx has a maximum length of 100 meters.
