接口：离散导线连接器和接线板-VMIVME-2540具有必须断开大量前面板输入/输出通过布线和可能的机架安装接线板。如果用户希望使用离散导线连接器和电缆，建议制造商为Harting Elektronik，Inc。，霍夫曼95710号邮政信箱212室斯托宁顿大道2155号伊利诺伊州Estates，60195-0710，（312）519-7700。这个连接P3和P3的推荐连接器组件P4如下表所示。RS-422差分信号应通过以下方式连接：24 AWG实心双绞线或绞合铜导线（R<30Ω/其他导线为1000英尺），最大电缆长度4000英尺。应注意确保每个信号机组正确接地，运行可靠。
3BHE037649R0101使用范围TTL信号可通过扁平96导线连接带状电缆，30 AWG绝缘铜绞线。
相应的96针DIN阴接头扁平带状电缆为ERNI 913.031或类似产品。它是建议电缆总长度为50英尺或以下关注最大信号的TTL应用速率和信号随距离的衰减。RS-422差分接口明显优于更长的电缆长度。MIVME-2540前面板将在端子处断开块，VMIACC-BT04双96针过渡面板建议。VMIACC-BT04是一种19英寸机架安装型从两个DIN 96引脚断开所有192个信号的面板标准接线板的连接器。之间的连接VMIACC-BT04和VMIVME-2540前面板为由96芯带状电缆制成，长度为3英尺推荐。商标VMIC标志是VMIC的注册商标。

INTERFACE: DISCRETE WIRE CONNECTORS
AND TERMINAL BLOCKS — The VMIVME-2540 has
a large amount of front panel I/O which must be broken out
by cabling and possibly rack-mounted terminal blocks. If
the user wishes to use discrete wire connectors and cables,
the suggested manufacturer is Harting Elektronik, Inc.,
2155 Stonington Ave., Suite 212, P.O. Box 95710, Hoffman
Estates, Illinois 60195-0710, (312) 519-7700. The
recommended connector components for cabling to P3 and
P4 are given in the table below.The RS-422 differential signals should be connected by
twisted pair insulated wires, 24 AWG solid or
stranded-copper conductors (R < 30 Ω/
1,000 ft for other conductors), with a maximum cable length
of 4,000 feet. Care should be taken to ensure that each signal
group is properly grounded for reliable operation.
TTL signals may be connected by flat 96-conductor
ribbon cable, 30 AWG insulated copper-stranded conductor.
The corresponding female 96-pin DIN connector for
flat-ribbon cable is ERNI 913.031 or similar. It is
recommended that the total cable length be 50 feet or less for
the TTL application with attention given to maximum signal
transition rate and signal degradation over distance. RS-422
differential interface is clearly superior for longer cable
lengths.MIVME-2540 front panel to be broken out at terminal
blocks, the VMIACC-BT04 Dual 96-pin Transition Panel is
suggested. The VMIACC-BT04 is a 19-inch rack-mountable
panel which breaks all 192 signals out from two DIN 96-pin
connectors to standard terminal blocks. Connection between
the VMIACC-BT04 and the VMIVME-2540 front panel is
made by 96-conductor ribbon cables, three foot length
recommended.
