(4) Pin headers for A-100 module connection (JP1 ...JP12)
These are the pin headers which are used to connect the A-100 modules. Up to
twelve modules can be connected:
•
Please calculate the total current requirement of the modules that have to be
driven by the A-100SSB/A-100LC1
•
Check that this total is less than 380 mA for both +12V and -12V rails.
Otherwise the A-100SSB/A-100LC1 is not suitable.
•
If +5V is used the current is taken from the +12V source. In this case the
currents for +12V and +5V have to be added and the sum has to be not more
than 380mA.
•
Check if each module is equipped with a ribbon cable with a 16 pin female
connector at the open end. The ribbon cable can be 10 or 16 pin but the
female connector has to be 16 pin !
•
Now join the free end of the ribbon cable to the nearest available position on
the bus board.
•
For this one has to plug the female 16 pin connector at the free end of the
ribbon cable to one of the pin headers of the bus (these are also 16 pins). Use
a pin header of the bus board that is close to the position where the module
has to be mounted later.
•
Check very carefully that it is connected so that the coloured marking on the
ribbon cable is at the bottom of the bus connector. The coloured marking
has to align with the "-12V" printing on the bus board next to the pin header. In
addition there is a line marked "RED WIRE" on the A-100SSB pc board. If the
bus connector does not fit into the boxed pin header (because the "nose" is on
the wrong side, i.e. left) do not connect the cable upside down (i.e. red on top)!
In that case please contact the manufacturer of the module and ask for a
suitable bus cable with the correct polarity of the connector.
•
Check also very carefully that it is pushed fully home, not at a slight angle
and not vertically or horizontally displaced .
•
Failure to check this may result in the module' s and/or supply's instant
destruction as soon as the power is turned back on!
•
When you' re installing extra modules, it may be necessary to take another
module or two out, to allow you easier access to the bus board.
•
Remove or install modules only during POWER OFF !
