It is connected respectively with the USB3.0 standard interface with multifunctional testing backboard with keyboard；By the keyboard and MouseAcross of general PS/2 interface
PS/2 one drag two cable is crossed to be connected with the PS/2 keyboard and mouse standard interface of multifunctional testing backboard；By general RS232 cable
The transmission pin and reception pin of one end DB9 plug are shorted, the RS232 standard interface phase of the other end and multifunctional testing backboard
Even；By the positive pin of transmission of one end DB9 plug of general RS422 cable and positive pin short circuit is received, negative pin is sent and receives
Negative pin is shorted, and the other end is connected with multifunctional testing backboard RS422 standard interface；By dedicated air plug cable and multifunctional testing
Backboard aerospace connectors interface is connected；
(3) system electrification, VGA display, which is normally shown, indicates that LRM mainboard display function is normal；Into after operating system, if USB
Keyboard and mouse can normal use then indicate that LRM mainboard USB interface function is normal；Into after operating system, if PS/2 keyboard and mouse
It can work normally, indicate that LRM mainboard PS/2 interface function is normal；
(4) serial ports test software is opened in an operating system, sends arbitrary data to RS232 serial ports, checks that serial ports receives data,
It is identical as serial ports transmission data to receive data, then proves that the RS232 serial port function of LRM mainboard is normal；It sends and appoints to RS422 serial ports
Meaning data check that serial ports receives data, and reception data are identical as serial ports transmission data, then prove LRM mainboard RS422 serial port function
Normally；
(5) step (2), (3), (4) operation are subjected to identical test under dedicated air plug cable, if test result and the above knot
Fruit is identical, then proves the function normal operation of aerospace connectors interface and LRM mainboard.
