XIII  Networking Challenges

As was pointed out before, 90% of all network challenges are cable related. In a bus network, not terminating the ends of the cable results in signal reflection or bounce, which can be the cause of all sorts of havoc. If a terminator is defective, which could happen easily if moisture got into the resistor, it could look just like no termination.

VOM Testing

If a network is not behaving test the cable and terminator with a VOM (Voltage Ohm Meter).


Somewhat more rare, but still quite vexing is not all Ethernet networks are created equal. In fact there are different types of Ethernet! This happened because Ethernet has been around quite a while.
