Hello list, Paul Anderson and myself are trying to figure out the available cabling options that allow to connect an RK611 controller to RK06/RK07 drives. To my knowledge, there is the possibility to get a drive connect via: RK611 <-> flat cable <-> cabinet transition bracket <-> round cable <-> RK06/07 The part numbers I found so far: Flat cable: BC-06R-xx round cable: 70-12292 or BC23Z-xx The transition bracket's PN is 70-12415 and is the same as for RL01/RL02 configurations. The round cable with same connectors as used for RL01/02 cannot be used for RK06/07 as not all cables are wired to the connectors. But a RK06/07 cable can be used for RL01/RL02. Can the BC-06R also be used for RL01/RL02? Apparently, there are also direct cable connections between RK611 and RK06/07 existing. In that case, no transition bracket is needed. BC80M shielded: RK611 to first drive ... and the cable required to connect two RK07/07 drives: BC17E shielded Can anybody help us in confirming and correcting us regarding the cabling configurations and the part numbers? Thanks a lot for your help!
