M-Net Control; 2-1.Transmission Cable Length Limitation - Mitsubishi Electric PUHY-RP-Y(S)JM-B 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.
Max. length via Outdoor (M-NET cable) L1+L2+L3+L4, L1+L2+L6+L7, L3+L4+L6+L7 <=500m[1640ft.] 1.25mm
Max. length to Outdoor (M-NET cable) L1+L8, L3+L4, L6, L2+L6+L8, L7
Max. length from MA to Indoor
