At this, advantageously use quad, particularly the star quad stranding quad is used for this data and connects, and this star quad stranding quad generally comprises an earth lead, power supply voltage lead and two single data leads.The same ground connection of this power supply voltage lead, thereby according to the present invention, two earth leads are used for shielding, and by advantageously around the signal conductor ground setting in other words of this data conductor, for example by stranded be net or coil.
Therefore propose according to the present invention, the Functional Capability of using the testing circuit device to come the data bonded assembly earth lead of the non-central authorities between the check stop pressure modulator, wherein the projector of testing circuit device sends detection signal to earth lead be arranged on receptor on other brake-pressure modulator and read this detection signal and then self assessment or transfer to apparatus for evaluating.
Particularly this detection signal can be in millisecond scope, that is to say, is in the scope of the following or 1kH of 1kH and is low frequencies for the data that transmitted thus.Can there be the vdc current potential equally.
The testing circuit device advantageously is directly installed in the data bus driver of brake-pressure modulator according to the present invention.This unified emission-and receptor be set at a plurality of brake-pressure modulators place, so it can check earth lead or connected to chassis power supply voltage lead respectively.
This testing circuit advantageously sends test voltage to the signal ground lead of data-interface with low frequency-resistance that limits and the high frequency-resistance that matches with the function of shielding of earth lead.In the receptor of target devices, earth lead be introduced in the sending-end impedance of qualification and this input end level detected.
The layout of this impedance is advantageously selected like this, and promptly for example, bypass resistance can not produce the mistake excitation of monitor levels owing to the humidity in cable junction or patchplug.
