ZETRON M30 PROGRAMMING
 

ENTERING PROGRAMMING MODE:
The number must be 5 digits in length, and is defaulted to 12123.
90# ______# PROGRAM ACCESS CODE 12123


SPECIAL FUNCTIONS:
The “*” key is used as a CLEAR key
The “#” key is used as the ENTER key


FROM A DTMF RADIO:
If the unit does not respond to your attempts to access the program
mode and the RECEIVE GAIN and CARRIER are set, check the DECODE
polarity jumper JP-6 and make sure it is in the correct position (“B” for an active
high decode or no decode input connected, and “A” for an active low decode
input).


To execute a program command, a DTMF number is entered followed by the “#” key.
Once the “#” has been entered, the Model 30 will respond with the 5 beep “go-ahead
chirp” indicating that the command was accepted or a high-low “error tone” sequence
indicating that an invalid command was received. Some commands require additional
numbers, as in the case of the connect code. For these commands, the Model 30 will send
two fast beeps indicating that additional digits are required.


Exit the Programming Mode:

INSTALLING THE EQUIPMENT:
POWER SUPPLY: 

+12Vdc lead to pin-1 / Ground lead to pin-2

TRANSMITTER PTT:

Connect a wire from pin-7 (PTT) to the PTT input of
the transmitter. Note that this output is a FET pull to ground.

TRANSMITTER AUDIO OUTPUT:

Connect pin-5 to the microphone input of
the transmitter, and braid to pin-6.

DISCRIMINATOR INPUT:

Connect pin-3 to the receiver discriminator output.
Shielded cable must be used for this connection, connect the braid to pin 2

COR INPUT:

Connect pin-8 to the carrier active sensor in the receiver. The
signal must be between 0 and 7 Vdc, and change at least 1 volt between carrier
and no-carrier conditions.
