1 Introduction
MTR-1 is a convert interface between
GTR-Series generator controller and PC for
communication purpose. It transforms RS-232
interface into RS-485. MTR-1, an electrical switch,
makes it possible for parameter setting and status
monitoring as well as controlling the generator by
your computer equipment such as Desktop,
Notebook, PDA, etc.. Relative connection software
