Pin Assignments

Cable Pin Assignments for the Coil Cable

The MS6720 scanners are terminated to a 10 position shielded modular connector. All of the coil cables (MLPN 44530) for the MS6720 scanner are terminated the same. The difference between versions is the end of the cable going into the scanner. This connector plugs into different “J” positions on various computer/interface boards. Since each computer/interface board is different, the output signals are different.
