connector on the COM-ML.
USB communication converter COM-K2-1 (with Loader communication cable [cable length: 1.5 m])
During the loader communication, the COM-ML requires an external power source. The
COM-ML will not function on the USB power from a personal computer alone.
The module address for loader communication is fixed at “0.”
Loader communication corresponds to RKC communication (based on ANSI X3.28-1976
subcategories 2.5 and B1).
When using the loader communication, USB driver for COM-K2 must be installed on the
personal computer.
The USB driver for COM-K2 can be downloaded the official RKC website:
