Issue:
NetBotz 750/755 require A-link terminators.

Product Line:
NetBotz

Environment:
NBRK0750
NBWL0755
NetBotz 5.x

Cause:
NetBotz 750 / 755 devices as well as A-link pods and A-link sensors ship with 1 A-link terminator. The terminator is required to reduce potential data collisions on the A-link bus. A number of different issues can occur if they are not used including but not limited to incorrect readings or even lost communications with pods or sensors.

Resolution:
When using the NBRK0750 which has 2 A-link ports, the configuration should be as follows:
1: No pods - terminator in bottom A-link port
2: Pods in 1 chain (either port) - terminator at end of chain. Terminator in open port
3: pods in 2 chains - terminate both chains

When using the NBWL0755, the configuration should be:
1: No Pods - No A-link terminator should be put in the A-link port.
2: Pods in chain - Terminator at end of A-link chain.

Purchasable sku for terminators is 0J-0W05545A
