EV-490 Transmitter

Overview:

The Secure Wireless sample transmitter for AMAC has two tact switches on the printed

circuit board (PCB) that allow flexibility in operation and programming. When in

standard AMAC mode pressing anywhere on the top of the button will ensure that either

or both of the PCB tact switches will be depressed. If any tact switch is pressed, the unit

will send its transmission immediately.

Programming:

In programming you can choose to change the serial number OR change the operation of

the transmitter from supervised to supervised with polling.

To change the serial number:

1) Press and HOLD both buttons on the AMAC sample transmitter. You will need

to press both the upper right and upper left corners of the one button to make

sure that you are pressing both buttons simultaneously.*

2) Continue holding the buttons, The LED will turn OFF after it is done

transmitting (approximately 3 seconds) and will turn back ON after

approximately 5 additional seconds, RELEASE both buttons.

3) Use the left tact switch for a ‘0’ and the right for a ‘1’. Example; if the AMAC

code that you desire is 28 then you will enter the data as follows;

0 0 1 0 1 0 0 0

_ _ _ _ _ _ _ _

4) You will also need to add a 0001 for a regular AMAC remote or a 1110 for a

silent panic type key.

I believe this encoding may be different from what you have done in the past but this is

the right format for Hex to Binary encoding.

5) Once all 12 digits have been entered the LED will flash rapidly.

* I have supplied a two button rubber insert for programming if you feel it is easier

during the programming sequences.

To change from Supervised to Supervised with Polling:

1) Press and HOLD both buttons on the AMAC sample transmitter. You will need

to press both the upper right and upper left corners of the one button to make

sure that you are pressing both buttons simultaneously.*

) Continue holding the buttons, The LED will turn OFF after it is done transmitting (approximately 3 seconds) and will turn back ON after approximately 5 additional seconds, WAIT until the LED begins to flash (approximately 5 seconds). The total hold time is approximately 13 seconds. Once the LED is flashing, Release buttons. 3) Press Button # 1 (left) for Standard AMAC supervised unit.

When the batteries are removed and replaced it will default to its original serial number and as a standard supervised AMAC remote. If the unit had any other programming it will need to be done again. Low Battery Trigger: Currently we check for a low battery every 12 hours for 3 consecutive wake ups. That means that when a low battery is detected we must see it on three consecutive occasions before we will lock and transmit low battery.
