Start with a memory test by typing M upper or lower case The program gives you a count of the number of successful tests or else reports failures If the test fails to run or reports failures check that the power supply is correctly set so that the board is receiving 5 0V and that the power supply is not current limiting The memory test is described more fully in section 3 3 Link test Check that the link cables are properly attached to the edge connector link cables are short lengths of pairs of twisted pairs with five way sockets 11 at each end As the edge connector is supplied Link0 should be connected to Link1 and Link2 to Links Reset the board and run the link test most likely failure is that it locks up and reports no successful test If this happens recheck that the cables are properly connected If the test runs successfully it will give a count of the successful tests UART test You have been using half the UART to control the tests via the terminal Much the easiest way to test the other half is to use the board transparently between a terminal and computer as described on the next page Otherwise you need a gender changer which not only turns the plug into a socket but also crosses over pins 2 and 3 of the 25 way connectors gt 3 3 7 Y After you have built or acquired such a gender changer reset the board type S and then U to run the U art echo test Unplug the terminal
