space 78 has an associated indicator light 80 that is easily identifiable with its associated bin space 78 for example a bin space 78a on the bin cart 44 has an associated indicator light 80a located immediately above the bin space 78a in the illustrated embodiment each of the indicator lights 80 of the bin cart 44 is arrow shaped and points at its associated bin space 78 this assists a user in identifying which bin space 78 corresponds to which indicator light 80 it will be appreciated however that the indicator lights 80 may take on any of a wide variety of shapes and sizes as discussed above the communication cable 46 extends between the chip handler 42 and the bin cart 44 the communication cable 46 is elongated and includes a first end 86 and a second end 88 in the illustrated embodiment the first end 86 of the communication handle 46 is coupled to the side wall 66 of the chip handler 42 near the location where the support bar 62 contacts the side wall 66 the second end 88 of the communication cable 46 is coupled to the side wall 72 of the bin cart 44 the communication cable 46 may have any of a wide variety of lengths however the communication cable 46 is desirably long enough to allow the chip handler 42 to be.
