產品詳情介紹
REXROTH VT-HNC100-1-23/W-08-0-0驅動模塊
串行和并行端口PC外圍設備包括兩個高速16550兼容串行端口（RS-232C）和一個ECP或EPP可配置并行端口。COM1可使用跳線配置為RS-485主板上的J8到J18（見第13頁）。
鍵盤接口
鍵盤接口使用前面板上的PS/2型連接器。+5V由多功能開關保護。如果+5V對GND短路，該設備將開路。一旦短路條件消除后，多功能開關將允許電流恢復。輔助/鼠標端口輔助端口接受PS/2兼容鼠標、軌跡球等。
行業包擴展XVME-660包括子板上的工業包（IP）模塊擴展。
Xycom銷售許多可與XVME-660一起使用的IP模塊。
小心IP規格如下。不要超過這些評級。
IP輸入/輸出電壓電平：69.29 VDC或49 VAC RMS
IP I/O隔離規范：從一個IP信號到另一個IP信號。
從一個IP信號到所有其他非IP信號，包括電源和接地。
每條軌跡將處理?A的電流。跟蹤將經歷當抽滿?a時，溫度升高30℃。
子板PMC擴展XVME-660支持可選的PMC（PCI夾層卡）擴展子板PMC擴展站點（一個5V PMC站點）。
進一步的PMC和PC/104擴展選項XVME-660支持可選的PMC（PCI夾層卡）和PC/104擴展
使用XVME-976擴展模塊。XVME-976/1提供了一個PCI夾層
板卡（PMC）站點和一個16位PC/104站點，XVME-976/104提供兩個16位
PC/104站點。這兩個XVME-976模塊都設計為直接插入
XVME-660使用子卡上的兩個80針擴展板連接器。看門狗定時器
XVME-660包含一個看門狗定時器
啟用后，計時器可以生成中斷或主重置，具體取決于您如何配置看門狗計時器
定時器輸入需要在1.0秒內切換，以防止超時。超時可導致復位或IRQ10（見第17頁）。
筆記超時范圍為1.0秒至2.25秒；通常是1.6秒。
軟件支持XVME-660與PC完全兼容，將運行“現成”的PC軟件，但
大多數軟件包將無法訪問VMEbus的功能。為了解決這個問題，Xycom自動化公司開發了廣泛的板級支持包（BSP），可以簡化VMEbus數據與PC軟件應用程序的集成。Xycom自動化的BSP為用戶提供了應用程序之間高效的高級接口以及VMEbus到PCI橋接設備。板支持包可用于MSDOS、Windows NT?、LynxOS和Solaris?, QNX?和VxWorks?
Serial and Parallel Ports
PC peripherals include two high-speed 16550-compatible serial ports (RS-232C) and an
ECP or EPP configurable parallel port. COM1 is configurable to RS-485 using jumpers
J8 through J18 on the mainboard (see p. 13).
Keyboard Interface
The keyboard interface uses a PS/2-style connector on the front panel. The +5V is protected with a polyswitch. This device will open up if the +5V is shorted to GND. Once
the shorting condition is removed, the polyswitch will allow current flow to resume.
Auxiliary/Mouse Port
The auxiliary port accepts a PS/2-compatible mouse, track ball, etc.
Industry Pack Expansion
The XVME-660 includes Industry Pack (IP) module expansion on the daughterboard.
Xycom sells many IP modules that can be used with the XVME-660.
Caution
The IP specifications are as follows. Do not exceed these ratings.
IP I/O Voltage Levels: 69.29 VDC or 49 VAC RMS
IP I/O Isolation Specifications:
Isolation up to 100 VDC or 70.7 VAC RMS from one IP signal to
another IP signal.
Isolation up to 354 VDC or 250.28 VAC RMS from one IP signal to
all other non-IP signals including power and ground.
Each trace will handle ? A of current. The trace will experience a
30C rise in temperature when drawing a full ? A.
Daughterboard PMC Expansion
The XVME-660 supports optional PMC (PCI Mezzanine Card) expansion using the
daughterboard PMC expansion site (one 5V PMC site).
Further PMC and PC/104 Expansion Options
The XVME-660 supports optional PMC (PCI Mezzanine Card) and PC/104 expansion
using XVME-976 expansion modules. The XVME-976/1 provides one PCI Mezzanine
Card (PMC) site and one 16-bit PC/104 site and the XVME-976/104 provides two 16-bit
PC/104 sites. Both of these XVME-976 modules are designed to plug directly into the
XVME-660 using the two 80-pin expansion board connectors on the daughtercard. Watchdog Timer
The XVME-660 incorporates a watchdog timer. When enabled, the timer can either generate an interrupt or a master reset, depending on how you configure the watchdog timer
port. The timer input needs to be toggled within 1.0 second to prevent timeout. Timeout
can cause either a reset or IRQ10 (see p. 17).
Note
The timeout range is from 1.0 second to 2.25 seconds; it will typically be
1.6 seconds.
Software Support
The XVME-660 is fully PC-compatible and will run "off-the-shelf" PC software, but
most packages will not be able to access the features of the VMEbus. To solve this problem, Xycom Automation has developed extensive Board Support Packages (BSPs) that
simplify the integration of VMEbus data into PC software applications. Xycom Automation’s BSPs provide users with an efficient high-level interface between their applications
and the VMEbus-to-PCI bridge device. Board Support Packages are available for MSDOS, Windows NT?, LynxOS, Solaris?, QNX?, and VxWorks?
