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.
