Installation
Verify the Disk recorder unit has the correct voltage specifications
for your power source prior to applying power.
(rear panel selectable 110/230 VAC)

Important remark :
It is recommended to connect the mains cable of the ADR to the mains plug
available on the power supply unit of the mainframe and leave the ADR mains
switch on the front panel turned ON permanently. This way, the mainframe and the
ADR will always start simultaneously when turning on the mainframe.
If the mains of the mainframe and the ADR are independent, make sure the ADR is
always turned on BEFORE the selected application starts loading.

Comment:
As the VDR and the ADR are two separate units and in order to ensure the audio
recording please check if the ADR rack unit is ON before loading the application,
the Audio parameter in the EVS menu is enabled, the RS422 link between units is
well connected, and both unit are genlocked with the same reference.

Comment: The Video Raid uses striping process across 5 disk drives. The video
data is striped over the first 4 drives (A, B, C, D) while the parity information is
saved on the fifth drive (E). If one drive (A, B, C or D) is damaged, the Video Raid
can use the parity information to recover the missing information if the RAID5
option is installed.

Comment: The VIDEO RAID Hard disk controller board has 5 SIMM’s RAM
banks. The CPU RAM is dedicated to the processor and the 4 video buffer RAM’s
are dedicated to the onboard SCSI-2 controllers. In standard configuration, the
Video Raid board is provided with 16Mb for the CPU and 32Mb for the Video
buffering. Therefore jumpers onto HCT are set on 32Mb (means: up to 32Mb).

Comment: As the VDR (Video Disk Recorder) and the ADR are two separate units,
the Genlock source is primordial and must be identical in order to avoid nonsynchronism problems (lipsync) between the video and the audio while recording or
playing back the material. On the rear panel of the Video Disk recorder unit, the
LOOP connector of the REF CB/BB is assigned to that end.

Note: During the test process some error messages could appear. In this case,
please note the error message and contact EVS for support.
The f i rst f our st ages exam i ne t he HCT4 board:
#1: reset s t he HCT4 board
The LED B on the HCT4 board flashes during this stage.
This reset command never stops the check process.
#2: checks t he doubl e access RAM by successi vel y wri t i ng and readi ng codes
i nt o t he COM RAM (U17) of t he HCT4 board
If the test stops at this stage, an error message advises you to check if the HCT4
board is well plugged or if the U17 device is present on the HCT4 board
#3: checks t he EPROM versi on
If the test stops here, an error message notices the EPROM code is not found
and advises you to check the U23 device on the HCT4 board.
#4: checks t he val i di t y and t he si ze of t he CPU RAM of t he HCT4 board.
If the test stops here, an error message notices the size of the CPU RAM is
insufficient or another message notices the CPU RAM is defect. In this case, we
advise you to start the MEMORY CACHE test for more details.
The next st age downl oads/ reads t he C H E C K . B I N f i l e:
#5: checks t he presence, t he val i di t y and t he versi on of t he f i l e.
If the test stops here, an error message notices the CHECK.BIN file cannot be read.
So this file is probably not present in the current directory or is damaged.
In this case we advise you to re-install completely the software.
The next t wo st ages exam i ne t he di sks. As t hi s concerns t he com pl et e SCSI
syst em , t hi s sect i on of t he t est l ast s m uch l onger.
#6: checks t he num ber of di sks’ t rays and t est s t he di sk cont rol l ers.
The st at us f or each di sk i s not i ced as f ol l ows: Ready, No di sk, or Not
ready.
During this stage, the CHECK.LOG file is updated. A Time Out message appears
when a major defect has been detected in the disks or in the disk connectors. In
order to locate precisely the defect, we advise you to read the LOG file or start the
DISK READ & VERIFY test.
#7: checks di sk organi zi ng and cal cul at es t he di sks’ capaci t y avai l abl e
accordi ng t o operat i onal di sk si ze param et er.
If the test stops here, this means that the HCT4 board is not working properly but a
dysfunction has been previously detected during stage #1, #2, #3 or #4.

#12: checks t he cache RAM and not i ces t he si ze avai l abl e.
If the test stops here, a message mentions a Time Out error.
This means that the microcode is not properly responding and the video buffer
RAM’s are probably implicated. In this case, we advise you to start the MEMORY
CACHE test for more details.
