[TowerTalk] Yaesu 450A Rotor Wiring Question

[Mike Ryan]

The instructions for the 450 rotator show a six pin plug for the 
control box and a SEVEN pin round connector that attaches to the actual 
motor drive unit. The instructions further say NOT to use pin #1 on the 
round connector.  Does that mean that pin#1 on both the control box plug and 
the round plug are not used?  Does this rotor then just use only 5 wires to 
operate?  Am I missing something?  How do the control box plug and the round 
connector wire? - Mike
