INSTALLATION

Your CES Model 600L DTMF Encoder microphone may be easily configured for the particular application. Power is supplied to the microphone through the radio's microphone connector for all functions, including: audible sidetone and keypad illumination.

If the Model 600L microphone was ordered for a specific application, a mating connector is installed; or, an appropriate connector may be installed using the information supplied below:

Cable Wire	Function
Color
BLUE	+12 VDC Input

RED	Push-To-Talk (logic low)

WHITE	TX Audio Output

BLACK	CTCSS Hang Up (logic low)

SHIELD	Audio/Logic Ground

YELLOW	Logic and Power Ground

CTCSS Hang Up (Monitor) is a logical function that will normally (as shipped) provide an off-hook (open-circuit) to the radio for CTCSS or DCS squelch "monitor" , or other decoder functions, and a logic low when placed on-hook. A grounded microphone hang-up clip is required.

A CTCSS Inverter is available as a factory option that provides reversed logic from the method described above. That is: the CTCSS Hang Up logic is an open-circuit when on-hook, and a closed circuit (logic low) when taken off hook.
