Problems!_________
If the system fails to power up check the following.
i.) Ensure that the Opto card is installed correctly.
ii.) Ensure that other cards in the PC have not been upset.
iii.) Ensure the power is connected and the PC is switched ON!
iv.) Ensure the Opto card i/o address is set correctly. Defaults
are Opto DIO48, Opto DIO16, Opto OUT24 and Opto
OUT48 all at 0308h, the Opto IN24 at 030C hex.
If all these have been checked and the PC still does not
power up then there is probably a conflict of i/o address between
the Opto board and another board in the PC. Ask your dealer to
check this or contact the HELP line as given on Intro page 2.
Screw Terminal Board._____________________
The easiest and tidiest way to connect your i/o card to
your rig is via the Screw Terminal Board.
The Screw Terminal Board converts from both 50 IDC
ribbon or 50D cable to screw terminals. The screw terminals can
take wire up to 2.5mm, 0.1 inch diameter. The 50IDC entry is a
latching connector, the 50D has screw locks to ensure hold fast
connections. The Screw Terminal Board comes complete with a
VERO box and removal lid, ready for mounting inside.
Power taken from the PC via the cards PWR=LNK jumper
is fed through a removable fuse and LED. Decoupling capacitors
are provided.
Each screw terminal, is clearly identified by IDC pin
number, and Opto DIO signal name, it can also take an optional
LED to show signal logic state. A handy cable grip clamps the
wires to ensure a robust, tidy layout. Order one now!
