Performing self-test

VS-606V7 is provided with a function to perform self-diagnosis for oper-

ation check of the serial communication I/F circuit. This function is

called self-test. In the self-test, connect the sending terminal with the

receiving terminal in the communication section. It assures if the data

received by VS-606V7 is not being changed. It also checks if the data

can be received normally.
