Ethernet cable - Pin configuration for PM series meters

[sesa354877]

What is the pin configuration that one has to maintain while crimping Ethernet cable for PM series meters? Do we need to use a straight Ethernet cable or crossed??

The meter behaves just like any other ethernet device so a straight ethernet cable will work fine.

Of course if you are directly connecting the device to a computer without a switch/hub then a cross over cable is correct in that (very rare) case.

Thanks Hal. One more question..not very sure about details of straight cable but there are two types seen in this type..T-568A or T-568B type?? which one should we go for?or it doesn't make difference as long as both ends or ethernet cabling through out system is of one type ?

( Just don't want to land up in a trouble at site so asking so many questions...;) )

You just need to be consistent with the wiring standard you use for both ends of the cable.

Cables are typically cheap to purchase.  If you can avoid crimping your own cables then it is strongly recommended to do so - cables made by a machine will be far better than anything us humans can make.  Debugging cabling issues at a customer site can be very time consuming (ie expensive).  Intermittent communication errors are quite hard to track down and you may not even see anything wrong other than sluggish responses as all the upper communication layers tend to retry on any errors.

Thanks Hal for inputs.
