Interfacing
Some general interfacing guidelines are presented below. Do not hesitate to contact the
factory if you need more assistance.
Watch the system grounds. All electrically connected equipment should have a fail
safe common ground that is large enough to handle all current loads without affecting
noise immunity. Power supplies and power consuming loads should all have their own
ground wires back to a common point.
Power all system power supplies from one switch. Connecting external voltage to
the IP-CF when it is not powered can damage it, as well as the rest of the host system.
This problem may be avoided by turning all power supplies on and off at the same time.
We provide the components. You provide the system. Safety and reliability can be
achieved only by careful planning and practice. Inputs can be damaged by static
discharge, by applying voltage less than ground or more than +5 volts with the IP
powered. With the IP unpowered, driven input voltages should be kept within .7 volts of
ground potential.
Terminal Block. We offer a high quality 50 screw terminal block that directly connects
to the flat cable. The terminal block mounts on standard DIN rails.

Many flat cable interface products are available from third party vendors to assist you in
your system integration and debugging. These include connectors, cables, test points,
'Y's, 50 pin in-line switches, breakout boxes, etc.
