Because numeral input and numeral are output as unidirectional communication process, digital input data capture card and digital output data capture card are when using two card direct communications, need to use simultaneously four data capture cards, i.e. two numeral input data collecting cards and two numeral output data collecting cards.Therefore, two pairs of digital communication joints are installed on the digital communication terminal circuit board 300, namely at the two ends of digital communication terminal circuit board 300 four digital communication joints are installed, wherein, two pairs of digital communication joints are used for assigning digital input data capture card and digital output data capture card.Particularly, when digital communication terminal circuit board 300 is used to form the digital communication loop, a pair of digital communication joint in the two pairs of digital communication joints is used for assigning the first digital input data capture card and the first digital output data capture card, and another is used for assigning the second digital output data capture card and the second digital input data capture card to digital communication joint.Wherein, the first digital output data capture card be connected the terminal place of digital output data capture card and connect the second output DC source terminal, thereby have access to the 5V direct supply that power module circuitry plate 200 provides.
Following digital input data capture card with
PCI-7433 is example, the digital output data capture card with
PCI-7434 is that example describes.Wherein, the terminal of above-mentioned two kinds of data collecting cards is the joint of 100-pinSCSI-II.Fig. 6 shows the shape of the terminal of above-mentioned two kinds of data collecting cards.
Loop works for numeral input and digital output can be formed need to apply 5V to the direct supply of 35V in communication loop.Fig. 7 shows the circuit of single DC digital input and digital output loop.As shown in Figure 7, the stitch at circular expression data collecting card terminal place, wherein VDD, DO and GND stitch are positioned at the digital output data capture card
On the terminal of PCI-7434, DI and COM stitch are positioned at the digital input data capture card
On the terminal of PCI-7433.R1 and R1 ' are respectively the equivalent resistance between DO stitch and VDD stitch among the PCI-7434, GND stitch, and R2 is the equivalent resistance between COM stitch and DI stitch among the PCI-7433.In order to reduce to access the power lead of power supply to the impact of communication loop, shorten the length of power supply circuit, at the two poles of the earth of terminal place access power supply, namely access the 5V direct supply that power module circuitry plate 200 provides.
As shown in Figure 8, because the 100-pin SCSI-II clamped nipple that PCI-7433 and PCI-7434 data collecting card use is two row's stitch, numeral input and digital output end sub-circuit board use double-sided printed-circuit board.Wherein, the left side is divided into the line of 1 to 50 stitch of digital communication terminal circuit board 300 positive PCI-7434 and PCI-7433 among Fig. 8, and the right side is divided into the line of 1 to 50 stitch of digital communication terminal circuit board 300 back side PCI-7434 and PCI-7433.
