Pin Assignments
Pin Assignments for the Coil Cable
The MS951 scanners are terminated to a 10 position shielded modular
connector. All of the coil cables (MLPN 44530) for the MS951 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.
