8-12 pin additional signal cable (for FELLOW / MATE-B)
12-pin additional signal cable on both ends (for MATE-A, long)
12-pin additional signal cable on both ends (for MULTi · short)
* An optional cable is required for the FELLOW / MATE-A / MATE-B 5-inch FDD model,
　The model number is not described in the manual.
8-pin mini connector for 8-pin additional signal cable is not mounted (pattern exists,
