Installing the board in the system Hardware Installation
Installing multiple boards synchronized by starhub
Hooking up the boards
Before mounting several synchronized boards for a multi channel system into the
chassis you have to hook up the boards with their synchronization cables first.
Spectrum ships the boards together with the needed amount of synchronization ca-
bles. All of them are matched to the same length, to achieve a zero clock delay
between the boards.
Only use the included flat ribbon cables.
All of the boards, including the board that carrys the starhub piggy-back module,
must be wired to the starhub as the figure is showing exemplarily for three synchro-
nized boards.
As you can see, all boards have a notch to get the cables to the other boards.
Please only use these notches to lay the cables to avoid damage to the cables when
inserting the boards into the host system.
It does not matter which of the 16 connectors on the starhub module you use for
which board. The software driver will detect the types and order of the synchro-
nized boards automatically. The right figure shows the three cables mounted next
to each other only to achieve a better visibility.
As some of the synchronization cables are not secured against wrong plugging you should take
care to have the pin 1 markers on the multiple connectors and the cable on the same side, as the
figure on the right is showing.
Mounting the wired boards
The locks on the top and bottom side of all CompactPCI brackets need to be unlocked and opened before installing the boards into the slots
of the system. Therefore you need to press the little buttons on the inside of the fasteners and move them outwards (see figure). Now slowly
insert the boards into the host system using the key ways until both locks snap in with a „click“.
While inserting the boards take care not to cant them and make sure that the cables are not squeezed by the
backplane or any other components.
After the board’s insertion fasten the screws of all brackets carefully, without overdoing. The figure shows exemplarily a board with two in-
stalled modules.
