Measurement Specialties CIO-SSH16 Computer Hardware User Manual


 
There are two cables used with CIO-SSH16; a signal cable and a power cable. The
power cable (C-PCPOWER-10) is supplied with the CIO-SSH16.
The power cable is black with two white MOLEX connectors. One end mates with
the J3 connector on the SSH16 and the other mates with any one of the available PC
power expansion plugs inside the PC.
The signal cable (C37FF-# or C37FFS-#) is a 37-conductor cable with 37D female
connectors at each end. One end plugs into the P18 connector of the CIO-SSH16, the
other plugs into the analog connector of a compatible analog input board (such as the
CIO-DAS16). (Figure 2-1).
2.2 POWER CABLE
A separate power cable is required because the CIO-SSH16 draws 1 amp from the
+5V supply to power the chips and the DC/DC converter which supplies the analog
components with +/-15V. This is more current than the C37FF cable should carry.
The C-PCPOWER-10 cable included with the CIO-SSH16 provides ample current
carrying capability.
The C-PCPOWER-10 power cable has two connectors, one male and one female.
The male end has metal pins, the female end, metal sockets.
The male connector will mate with any of the unused PC power expansion plugs
inside your PC. It is likely that there are unused plugs attached to wires which come
from the PC power supply on your PC. If not, order the C-PCPOWER-Y adapter to
add another connection. Plug the male end of the C-PCPOWER-10 power cable into
one of the unused power connectors.
Run the C-PCPOWER-10 power cable out the back of the PC. Use an expansion slot
or other orifice. If you prefer a connection external to the PC, the BP-POWER
adapter is available to bring the power connector out to a bracket that mounts in an
unused expansion slot.
WARNING
Use care so that the C-PCPOWER-10 power cable is not pinched by
the PC case. If the cable were severed, a serious short circuit would
result, possibly damaging your computer.
Power to the SSH 16 is supplied via a four pin MOLEX connector. This connector is
the exact mate of the standard PC Power supply expansion power connector. The
expansion power connectors are located inside the PC and carry +5V, +12V and
Ground. They are used primarily for disk drive power, but, there are more power
expansion connectors than you are likely to use (Figure 4-2) .
