2. Check that LD210 (7 seg. LED’s) of the PN-LED circuit board light one by one in the order of “0, 1, 2, 3, 4, 5, 6, 7, 8, 9, .”.
3. Check that all LED’s light up at the end.
5. Testing of AES circuit board
5.1 Connection
Using the USB cable, connect CN308 of the MAIN circuit board and the USB terminal of PC.
Using the serial cable (cross), connect CN504 of the AES-AES 1 circuit board and the serial terminal of PC.
Set SW201 of the MAIN circuit board to “0”.
Connect the BNC cable to JK306 of the PN-JACK circuit board. (WORD CLOCK IN-OUT)
Connect the MIDI cable to JK303 of the PN-JACK circuit board. (MIDI IN-OUT)
Connect the “reflected jig B” to CN301, CN401 of the AES-AES1 circuit board and CN701, CN801 of the AES-AES2 circuit
board. (AES/EBU [1~4])
Connect the “reflected jig A” to CN901 of the AES-AES2 circuit board. (COM)
