J7 (Receive Timing): “B” Position
B. The configuration of the IMUX 2000 RS-449 Channel Card shall be as follows:
1. DS-562NC with MA-406IA I/O
MA-406IA I/O: J2 jumpers in DCE mode
J3 in any position
DS-562NC, Switch SW6-5 (Receive Clock Polarity): Normal - OFF (DOWN)
DS-562NC, Switch SW6-7 (Transmit Clock Polarity): Normal - OFF (DOWN)
C. Confirm Clock and Data Transitions to Insure Proper System Operation as follows:
1. RFL 9720 CCM: The positive edge of the RxClock (TP17) must be in the center of the
RxData bit (TP16).
