M-Net Control - Mitsubishi Electric CITY MULTI PEFY-P22VMS-E-S Data Book

2. M-NET control

2-1. Transmission cable length limitation
2. M-NET control
2-1-1. Using MA Remote controller
Long transmission cable causes voltage down, therefore, the length limitation should be obeyed to secure proper transmission.
