PROBLEM TO BE SOLVED: To reduce power consumption as much as possible, and to satisfy a timing regulation on signal transmission, and to accurately transmit a signal even when transmitting the pattern of a signal causing an increase in the distortion and corruption of a signal waveform.SOLUTION: Data communication equipment includes a first communication device and a second communication device. The first communication device includes: a transmission buffer part; a pattern generation part for generating a test pattern; a switching part for switching the level of the output current value of the transmission buffer part; and a determination part for determining the transmission result of the test pattern. The second communication device stores a test result as the reception result of the test pattern in each level of the output current value. The determination part acquires the test result from the second communication device, and allows the transmission buffer part to transmit data in an application level as a level in which the output current value is the smallest out of each level of the output current value in which the test pattern can be normally acquired.SELECTED DRAWING: Figure 5 |
