NI PXIe-5652這些跳線位置（標(biāo)記為JP2、JP3和JP4）可通過移除轉(zhuǎn)換器頂部的方形塑料蓋來(lái)訪問。NI PXIe-5652可以根據(jù)需要更改配置，方法是使用一對(duì)尖嘴鉗小心地移除一個(gè)或多個(gè)跳線，并將其放置在所需的一對(duì)引腳上。請(qǐng)參閱下表中這些可選跳線位置的說明，并將跳線放置在所選引腳對(duì)上。NI PXIe-5652管腳編號(hào)為1、2和3。默認(rèn)跳線位置由每個(gè)位置的跳線引腳周圍的矩形表示。默認(rèn)管腳編號(hào)為1和2。當(dāng)與PLC通信的設(shè)備不提供載波檢測(cè)信號(hào)時(shí)，使用默認(rèn)位置1和2。JP2強(qiáng)制RS-485端口上的DCD信號(hào)激活。如果設(shè)備確實(shí)提供載波檢測(cè)信號(hào)，請(qǐng)使用跳線位置2和3。這允許編程設(shè)備控制DCD。當(dāng)連接的調(diào)制解調(diào)器不需要清除發(fā)送（CTS）信號(hào)時(shí)，使用默認(rèn)位置1和2。這允許編程設(shè)備控制RTS信號(hào)。NI PXIe-5652
These jumper positions, labeled JP2, JP3, and JP4, are accessed by removing the square plastic cover on the top of the converter. Configuration NI PXIe-5652can be changed as required by carefully removing one or more of the jumpers with a pair of needle nose pliers and placing it on the desired pair of pins. Refer to the description of these selectable jumper positions in the following table and place the jumper on the selected pair of pins. The pin numbers are 1, 2, and 3. Default jumper locations are indicated by a rectangle around the pins to be jumpered for each position. NI PXIe-5652The default pin numbers are 1 and 2.Default position 1 and 2 is used when the device communicating with the PLC does not supply the Carrier Detect signal. JP2 forces the DCD signal active on the RS-485 port.NI PXIe-5652Use jumper positions 2 and 3 if the device does supply the Carrier Detect signal. This allows the programming device to control DCD.Default position 1 and 2 is used when an attached Modem does not require the Clear To Send (CTS) signal. This allows the programming device to control the RTS signal.
