Handwheel Encoder Termination Resistors
The PMAC provides a socket for termination resistors on the handwheel encoder differential input pairs
coming into the board. As shipped, there is no resistor pack in the RP56 socket. If these signals are
brought long distances into the PMAC board and ringing at signal transitions is a problem, a SIP resistor
pack may be mounted on the RP56 socket to reduce or eliminate the ringing. The 6-pin termination
resistor pack is the type that has independent resistors (no common connection) with each resistor using 2
adjacent pins.
