2.产 品 详 情 资 料：
NI PXIe-8135当连接的调制解调器确实需要CTS信号时，使用跳线位置2和3（大多数调制解调器需要此信号）。强制RTS持续激活。默认位置1和2用于通过串行编程设备与PLC通信的大多数应用。如果与PLC通信设备旨在模拟HHP协议，则使用跳线位置2和3*有关信号要求，请参阅串行设备的文档。电缆配置示例使用转换器时所需的电缆配置示例可在附录C中找到。转换器的规格如下表所示。NI PXIe-813525针D型母超小型（转换器端）9针、15针、，或25针（取决于串行设备上的连接器类型）D型微型内螺纹（编程设备端）产品目录编号仅供参考。任何具有相同电气特性的电缆均可接受。强烈建议您使用绞合线。NI PXIe-8135由于有时很难找到具有所需数量双绞线的电缆（Belden 9309有一对额外的双绞线），因此您最终可能会得到一条具有额外双绞线的线缆。
Jumper positions 2 and 3 are used when the attached Modem does require the CTS signal (most modems require this signal).NI PXIe-8135Forces RTS to be continually active.Default position 1 and 2 is used for most applications communicating with the PLC via a serial programming device.Jumper positions 2 and 3 are used if the device communicating with the PLC is intended to emulate the HHP protocol. *Refer to the documentation for your serial device for signal requirements.Example of Cable Configurations Examples of cable configurations required when using the converter can be found in Appendix C. Specifications for the converter are shown in the following table.25-pin D-type Female Subminiature (converter end) 9-pin, NI PXIe-813515-pin, or 25-pin (depending on type of connector on your serial device) D-type Female Subminiature (programming device end)Catalog numbers are provided as suggestions only. Any cable having the same electrical characteristics is acceptable. It is strongly recommended that you use stranded wire. Since it is sometimes hard to find a cable with the desired number of twisted pairs (the Belden 9309 has an extra pair), you may end up with a cable with extra pairs.NI PXIe-8135
