DC-Digital CM-1 Installation Procedures Manual
   |
Procedure for installation of the CM-1:Receiving Procedure:- Remove CM-1 from packaging.- Inspect CM-1 for damage from shipping.- Notify IES ASAP if damage has occurred during shipping.Locate the CM-1 within 25 ft. of the computer that will be running the EZ-Time Softwareand within 6 ft. of a single duplex 120 VAC Outlet.Field Wiring Procedure:The CM-1 is a computer controlled serial data converter. Its job is to convert low levelserial data (that is sent from any computer com port having an RS-232 COM port or USBto RS-232 COM port converter) to high level data. The high level data that the CM-1 willoutput is to be connected to all DC-Digital peripherals that require EZ-Time data.Before supplying power to the CM-1, connect the field wiring.Connect the Data input line:Connect the CM-1 to the Computer that will be operating the EZ-Time Software.The CM-1 comes with a 25ft RS-232, Male to Female (DB-9) Data Cable. If connectingto a computer using a USB COM port a USB to RS-232 (BD-9) converter will be needed.Call DC-Digital to order a converter cable, 800-977-6872.Connect the 25 ft. RS-232 (DB-9) cable to the Computer COM port and to the back of theCM-1 RS-232 COM input Port.Make sure all connections are secure at both ends.Connect the Data output line:Use 22 Ga. Low voltage cabling to connect to the CM-1 output.Make sure to follow the polarity of the CM-1 data output when connecting to DC-Digitalperipherals:+ to +, - to -.- Data + = Data Output to the + of all data receiving peripherals. (DC-Digital Color is White)- Data - = Data Output to the - of all data receiving peripherals. (DC-Digital Color is Green)See typical wiring Diagram below. |
