Connect the Power

 
Make sure that the CM-1 will be receiving 120 VAC @ 5 amps of clean dedicated power. 
Do not connect the CM-1 to power lines that share AC Motors, Heaters, or Inductive 
loads. This will cause sporadic data transmission and undesirable results in correct data 
transmission and reception. 
 

-

 

Use the provided 

24VDC at 1 Amp

 wall transformer to power the CM-1. 

Note: The use of any other wall transformer other than what is required by DC-
Digital will void warranty. 

 
Observe: 

-

 

The RED 5 volt LED will light. See Picture….. 

-

 

The Data RED LED will flash every time the EZ-time Software sends data out of 
the designated computer COM Port either manually or automatically. See Picture 
for location of the RED Data LED. 

 
NOTE: The GREEN LED must stay on steady and RED LED must flash to indicate 
correct CM-1 operation.
