APPENDIX C
Pin Assignments for the Coil Cable
The MS6720 scanners are terminated to a 10 position shielded modular
connector. All coil cables (MLPN 44-44780) 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.
