Below five kinds of interface modules in this interface equipment are introduced respectively, shown in Fig. 2-6, J1, J2 among the figure ... all represent interface or binding post.
1. alternating current filter interface module:
As Fig. 1, this interface module receives the control signal from MACH2 XS853 module.Because the output of XS853 module is the passive bus signal, interface module need provide power supply for this signal circuit, and just the passive bus signal converts voltage signal on this module.Two emulators all are the switching value signals that receives, but voltage signal (providing uA level electric current to get final product) only is provided analog simulation equipment, but Digital Simulation equipment needs voltage signal that certain driving force is arranged.So change-over circuit is designed to, output voltage was not less than the interface circuit of 18V when the 4mA drive current was provided.In addition because and connector type difference on analog simulation equipment and the plate that Digital Simulation equipment is connected, so the different connector of needs connect two cover systems.The analog simulation equipment requirements be 75 ohm of coaxial connectors; What then select for Digital Simulation equipment is the quick wiring connector apparatus of certain brand.Wiring connector apparatus is divided into socket and plug two parts fast.Socket refers to the part of installing on pcb board, its feature is: realize the connection density of twice in the spacing of 3.50mm, than the general connector of 2.50/2.54mm spacing conserve space more, significantly increased the port number of input and output in little space.Plug refers to panel leading-out terminal part, is characterized in: the connecting conducting wire sectional area can reach 1 square millimeter (plain conductor), the connector of alternative 2.50/2.54mm spacing, and on panel, reduce by 30% space hold.Adopt the shell fragment connection technique, operation is with easier for installation quick.
2. trigger impulse interface module:
As shown in Figure 3, this interface module receives from MACH2,24 road warbled difference ignition pulse signals of XS930 module, and differential voltage is 5V.This interface module becomes differential signal into single-ended 5V level signal earlier, and then this differential signal is sent into CPLD decode, and after the decoding, the Transistor-Transistor Logic level conversion of signals that CPLD is exported becomes the 24V voltage signal, exports to different emulators.
The characteristics of frequency modulation(FM) differential signal are: represent digital quantity " 1 " if differential signal is the square-wave signal of 1Mhz, do not change in 2us if differential signal is 5V, then represent digital quantity " 0 ".

And Digital Simulation equipment provides the sky node signal, and interface module becomes empty node signal into voltage signal earlier, enters reverse link then.The effect of the reverse link of mentioning in the effect of this reverse link and the epimere is the same.
Two paths of signals through level conversion is input to or the door selection simultaneously, isolates then, and the signal after the isolation is sent into single-ended variation branch link, with TTL 5V level signal, becomes the RS422 differential signal, exports to MACH2 by the single phoenix terminal of 5.08 spacings.
Because of the same time has only a kind of emulator access interface module, thus or the input of door, have only one tunnel input effectively; Another road is not because import, so be " 0 " always.Process or door are selected, and the signal of the feasible emulator that has connected passes through, and finally exports to the MACH2 system.
