The key can be used to erase the last character entered. If you have already entered

some characters, the ape key can be used to erase all the characters you have entered thus
far. If you try to enter more characters than the command calls for, the extra keystrokes will ÔscrollÕ.
Hitting the key will tell the AB/DR-3000 to accept your entry as typed. If the entry is invalid,
the AB/DR-3000 will beep annoyingly and ask for the same input again. If at any point you enter a com-
mand and have yet to enter any other characters, you can leave the command by hitting the
ape or key.

The configuration of a AB/DR-3000 can be locked at any time by simply removing JP-7 pin #1 to #2

and moving it to pin #2 to Pin #3

. The AB/DR-3000 will warn you when you enter the setup mode if

the configuration EEPROM has been locked.

Note that only one card in the entire system is allowed to be in configuration mode at one time. For

this reason, if you try to put a card that doesnÕt exist into configuration mode, not only will you not see a
configuration screen from that nonexistent card. No other card in the system will want to listen to you
until you take the nonexistent card out of configuration mode. To do this, type a:

x n

. The other AB/DR-

3000s will then start listening to you again.

Card Address:

Card address used by serial port commands and configuration. The address is displayed on the front

of the repeater each time it is turned on. Only one device on the same serial network can use the same
address. For AB-3000s, which usually run solo, this usually present no problem and the default 00 ad-
dress can be used.

For card cage mounted DR-3000s, the addresses must be set to talk to any of the DR-3000s within

the cage. This can be done through the serial port only if one card is installed at a time, and has its ad-
dress set before installing the next card.

VT-52 Terminal:

When this toggle is enabled, the AB/DR-3000 will use special escape sequences to clear the current

line (ape 'l'), or position the cursor (ape 'Y' ROW COLUMN). When disabled, the AB/DR-
3000 has to redraw the entire screen to change any value, so it can save a good deal of screen redraw
time if you have a compatible display. Virtually all terminal programs will support VT-52 terminal emula-
tion.

ÒcÓ

Numbers:

This toggles the AB/DR-3000 between Decimal (0 to 255) and Hexadecimal (00 to FF) numbering sys-

tems. In most cases these will turn to absolute values when Hex mode is selected. The table at the back
of this manual will allow you to translate between these different numbering systems if necessary.

All commands received through the serial port will use the HEXadecimal numbering system, regard-

less of which has been selected.

This setting will have no effect on the front panel display. It will show spiel numbers as decimal values

(00 to 99) unless more than 100 spiels are stored on a repeater. It will then use HEXadecimal numbers.

ÒdÓ

Input Debounce:

This command is used to set the number of times the software in the AB/DR-3000 will check the serial

port input for the same value when operating in IR Mode. Too small a value will cause the AB/DR-3000 to

Some earlier versions of the AB/DR-3000 only had two pins for JP-7. Insert a jumper across these

two pins to protect the configuration memory, and remove it to allow full access.
