5.2 Testing method
Select “3. NHB32-C AES SHEET” on the start-up screen of the TEST PROGRAM, and testing of following test items is executed
automatically.
1 DIO : AES/EBU test
Automatic judgment
2 COM : COM LOOP BACK test
Automatic judgment
6. Testing of PN circuit board
6.1 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)
Select “4. NHB32-C PN SHEET” on the start-up screen of the TEST PROGRAM, and testing of following test items is
To start the following testing, press the “ENTER” key of the keyboard.
