Configuration and Cable Group Selector
Use the chart below and the Cable Selection Guide table that follows
it to determine which cables are appropriate to your own application.
To use the chart, simply identify the scanner you are using in the
center column, then look to the left if you are using a NEMA Type 1
decoder, or to the right if you are using a NEMA Type 4 decoder. A
cable group identification number appears over the line connecting
your scanner with your decoder type. For example, if you are using
an -LD4 scanner with a NEMA Type 4 decoder, you would select a
Group II cable.
