Emerson 400276-01 operation manual TIX-XXX & TIA-XXX Wiring Diagrams 525 PMC To IBM Serial Port

525 Programmable Motion Controller

In 525's, the signal terminator capacitance is approximately 1000pf and a typical cable capacitance runs about 30pf/ft. Therefore, the cable length should be limited to 50 feet. Longer serial interface cables are not recommended.

In multi-drop configurations, the ground reference (earth ground) for each communicating device must be at the same potential. The further apart the communicating devices, the more difficult this is to achieve. Therefore, it is a good idea to keep the multi-drop loop as short as possible. This condition is not as critical if all of the communicating devices are optically isolated.

It is very important that the serial cables are not altered in the field. It is also important to follow any recommendations given in the product manuals on how to connect or terminate these cables.

NOTE: As a general rule, the minimum cable bend radius is ten times the cable outer diameter.
