To use the 73xx boards with a CB-68LP you need the SH68-C68-S cable. The CB-68LP has the same connector like the UMI-7764 so you need to use the same cable. The SH68-68-D1 cable is not an option as it doesn't fit to the 73xx boards.
SH68-C68-S order information:
2 m ...........................................186381-02
0.5 m .........................................186381-0R5
