Stuart, if the rest of your network isn't an outragious distance total, check these things:

1. All cable is exactly the same type, i.e., CAT5e. What's not so important is what type (5, 5e, 6, bell wire, etc.). What is important is consistency - i.e. all cable pieces are exactly the same cable type, manufacturer, etc.

2. Your network is perfectly linear. If you have a sensor on the end of a 100' segment, make sure this is segment is the last piece of a linear topology.

3. Take an oscilloscope out to the last sensor and look at the waveforms. This can confirm if you have a marginal bus communication challenge or something else.

Best regards,

Bill
