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 Software

and 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 level

serial data (that is sent from any computer com port having an RS-232 COM port or USB

to RS-232 COM port converter) to high level data. The high level data that the CM-1 will

output 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 connecting

to 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 the

CM-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-Digital

peripherals:

+ 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.
