Acceptor Interface Output Test
This is the test of output signal line from the acceptor to external I/F port and VM-30 mode display LED.
This is also the output test of red and green LEDs of acceptor.

Acceptor Interface Input Test
This is the test of acceptor's input signal line (external I/F port). The status of the input signal line is
shown on the VM-30 mode display LEDs.
