MR816CSX/MR816X
5-6-5. Test contents
(1) Connection checking of the A-BUS between the
SSP1 and connection checking of the audio signal
cable between the SSP1 and DICEII are conducted
automatically on entering the test.
(2) Then, lock checking of the [WCLK], [S/PDIF] and
[adat] terminals with loopback connection and audio
check will be conducted automatically.
(3) Then, the test will be fi nished.
The test item selection mode will follow automatically
when the test is fi nished.
If you want to abort the DIGITAL I/O test, press the
[ASSIGN 2] encoder.

No. 6 1394_CONNECT test
5-7-1. Outline
Checks 1394 peripheral device on the DM circuit board
and connection.
5-7-2. Main devices to be tested
• 1394 peripheral device
5-7-3. Preparations
Connect one each 1394 hub (S400 compatible) to the two
1394 connectors of the MR816CSX/MR816X with 1394
cables.
5-7-4. Test method
Turn the [ASSIGN 1] encoder to turn on the LED
corresponding to the 1394_CONNECT test and then press
the [ASSIGN 1] encoder to execute the test.
The LED for the [ASSIGN 2] encoder corresponding to
the 1394_CONNECT test lights up if the test result is OK
or doesn't light if the result is NG.

(Test item selection)
5-7-5. Test contents
If the number of nodes is obtained correctly, the 1394
peripheral device and connection check are judged as OK.

6.1394 CONNECT
(Test result)
(Fig. 19)
If 3 nodes in total (two 1394 hubs and one MR816CSX/
MR816X connected to the connectors) are recognized, the
test result is OK.
The checking is conducted automatically and the test item
selection mode will follow in case of OK.

FPGA version indication
6-1-1. Outline
Program version of the FPGA on the DM circuit board is
shown with the LEDs on the panel of the MR816CSX/
MR816X.

• FPGA
6-1-3. How to check
LEDs for the [QUICK CONNECT 6] to [QUICK
CONNECT 8] indicate the FPGA version in the ANALOG
test mode (just after starting the test program) when the
[QUICK CONNECT 5] button is pressed.
The correspondence between the FPGA version and LED
indication is as follows.
