Hints and Tips

A few simple suggestions that may assist you if your system is experiencing problems

include:

• Slowing down the polling rate may be helpful if power cycling doesn’t cure the

problem.

• A common misperception is that every serial network must terminate with a resistor.

While this was true of early serial network configurations, it’s typically the wrong

answer – call our technical support and verify if you’re an exception, at 815.433.5100

option 3.

A sometimes difficult problem is difference in grounding voltage between various network

locations. Stray voltage from lightning or other sources may also find its way onto the network.

These conditions make isolation necessary in many settings.
