HONEYWELL TK-FPDXX2控制系统,TK-FPDXX2配置说明
输入/输出总线扩展电缆（IC693CBL300、301、312、313、314）称为“Y形电缆”，具有一端和双头（一公一母）的单阳25针D连接器另一端的25针D连接器，如图（A）所示。50英尺（15m）（IC693CBL302）电缆在CPU基板端有一个阳连接器和一个扩展基板端部的端接公连接器。3英尺电缆（IC693CBL300）也可以用作Y形适配器电缆，以简化构建自定义长度电缆（见本章下文“电缆应用建议”一节）。
HONEYWELL TK-FPDXX2控制系统电缆的功能输入/输出总线扩展电缆用于将输入/输出总线扩展到扩展或远程当需要额外的输入/输出插槽或基板需要与CPU基板保持一定距离。预接线输入/输出总线扩展电缆可用于连接扩展或远程基板。如果标准电缆中没有所需的电缆长度，则必须使用自定义电缆已建（有关详细信息，请参阅“构建自定义长度输入/输出总线扩展电缆”一节说明）。连接电缆将单个阳接头连接到右侧的25针阴接头CPU基板。将电缆双连接器端的公连接器连接到25针第一个扩展基板上的阴连接器。将未使用的25针内螺纹连接器连接到电缆的双连接器端连接到第二条输入/输出总线扩展电缆的单个公连接器以继续输入/输出总线扩展链，或连接到输入/输出总线终端插头（如果这是最后一根电缆）在扩展链中。
I/O bus expansion cables (IC693CBL300, 301, 312, 313, 314), called “Wye cables,” have a
single male 25-pin D connector on one end and a two-headed (one male, one female)
25-pin D connector on the other end as shown in (A) of the figure. The 50 foot (15m)
(IC693CBL302) cable has a single male connector on the CPU baseplate end and a single
terminated male connector on the expansion baseplate end. The 3 foot cable
(IC693CBL300) can also be used as a WYE adapter cable to simplify building custom length
cables (see the section “Cable Application Suggestions” later in this Chapter).Function of Cables
The I/O Bus expansion cables are used to extend the I/O bus to expansion or remote
baseplates in a Series 90-30 I/O system when additional I/O slots are needed or
baseplates are required some distance from the CPU baseplate. The prewired I/O bus
expansion cables can be used for connecting either expansion or remote baseplates.
Where required cable length is not available in a standard cable, a custom cable must be
built (see the section “Building Custom Length I/O Bus Expansion Cables” for detailed
instructions).Connecting the Cables
Connect the single male connector to the 25-pin female connector on the right side
of the CPU baseplate.
Connect the male connector on the dual connector end of the cable to the 25-pin
female connector on the first expansion baseplate.
Connect the unused 25-pin female connector on the dual connector end of the cable
to either the single male connector of a second I/O bus expansion cable to continue
the I/O bus expansion chain, or to an I/O bus Terminator plug if this is the last cable
in the expansion chain.
