RELIANCE 615055-1R交流電源模塊
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從接線集線器到終端節(jié)點(diǎn)的最大長度為100米。100BaseTxVMIVME-7740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的最大部署長度為250米。LANWorks VMIVME-7740以太網(wǎng)控制器支持使用LANWorks以太網(wǎng)BIOS進(jìn)行遠(yuǎn)程引導(dǎo)。有關(guān)遠(yuǎn)程以太網(wǎng)引導(dǎo)的更多信息，請(qǐng)參閱附錄D。VMIC的VMIVME-7740具有典型IBM PC/AT兼容SBC之外的其他功能。該單元提供三個(gè)軟件控制的通用定時(shí)器以及一個(gè)可編程看門狗定時(shí)器，用于同步和控制嵌入式應(yīng)用程序中的多個(gè)事件。VMIVME-7740還提供了可引導(dǎo)的閃存系統(tǒng)和32K字節(jié)的NVRAM。
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 m from the wiring hub to the terminal node. 100BaseTx The VMIVME-7740 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 deployment length of 250 m. LANWorks The VMIVME-7740 Ethernet controller supports remote booting using the LANWorks Ethernet BIOS. Refer to Appendix D for more information on remote Ethernet booting.VMIC’s VMIVME-7740 features additional capabilities beyond those of a typical IBM PC/AT-compatible SBC. The unit provides three software-controlled, general-purpose timers along with a programmable Watchdog Timer for synchronizing and controlling multiple events in embedded applications. The VMIVME-7740 also provides a bootable Flash Disk system and 32 K byte of NVRAM.
