SYSTEM POWER-UP
First Time Power-up
Turn the POWER switch on. The factory loaded defaults are already
installed in memory. Adjust the display contrast as desired.
After programming, adjust the red RADIO RANGE knob next to the
antenna to limit the maximum range of the receiver. Start with the knob
fully counterclockwise, this will be minimum range. Adjust the range
up as required by the installation. This can be determined during
testing.
Internal Diagnostic Checks
The AM/II performs an automatic internal diagnostic check when the
system is first powered up. The system checks itself to be sure
everything is in order. The internal check takes about 5 seconds. The
display will indicate that start-up is occurring, the firmware version
number, the date of manufacture and the serial number. If all tests are
good, the display will show “ALL STARTUP TESTS PASSED”.
Watchdog Monitor
While the system is operating, an internal “watchdog” circuit monitors
the system. If for some reason (lightning strike, etc.) the system is
upset, the watchdog monitor will reset the system, restoring system
integrity.
MEDIA ENCODING
All code data is stored in the non-volatile EEPROM memory module.
Even with complete loss of all power, the AM/II will remember all of
the media code data.
Transmitter Coding
There is no programming of transmitter codes or setting of dipswitches
required to set up the system. Each transmitter is preset at the factory
to a unique code. With over 1,000,000 codes available, the MegaCode
format virtually eliminates any possibility of transmitter code
duplication. Since the AM/II “learns” specific transmitter codes, no
unauthorized person can gain access by reprogramming a
transmitter.
Block Coded Transmitters
Sequentially “block-coded” transmitters are available to speed
installation and programming and simplify installation record keeping.
The entire transmitter block can be programmed into the system by
simply entering the first and last transmitter in the block.
Block transmitters are identified with two numbers:
1.
A transmitter number in the range of 1-65,535 is printed on a
label on the back of the transmitter.
2.
A facility code in the range of 0-15 is printed on the block
transmitters’ box.
Block Coded Cards
Sequentially “block-coded” cards are available for use with card
readers attached to Model AM-CRI card reader interface. The entire
card block can be programmed into the system by simply entering the
first and last card in the block.
Keypad Entry Codes
Keypad entry codes are programmed one at a time.
