4.1.4 Set Code Length
This command allows you to change the maximum number of digits used in codes. Larger
customer codes reduce the probability of a jackpotting of the system by guessing random
numbers. For example, if the valid codes database is filled with 5,000 carwash codes and the
code length is set to 6 (maximum code is 999990) a 10% probability of jackpotting exists, or 10
random codes would have to be tried on average to jackpot the system. With the same 5,000
valid codes but a maximum code length of 7 (maximum code is 9999990) a 1% probability of
jackpotting exists, or 100 random codes would have to be tried on average to jackpot the system.
Note that with a multiple-console configuration, when code length is changed on the master
console, it is immediately downloaded to the remote consoles.
To select this command scroll through the System Configuration secondary menu until "Set Code
Length" is displayed and press the [ENTER] key. Once selected, the console prompts you to
enter the maximum code length as 5, 6, or 7. Press 5, 6 or 7 as desired followed by the [ENTER]
key.
Example to set code length to 6 digits:
[CMD]
[SYSTEM SETUP]
[3]
(password 3)
[ENTER]
[MENU UP/DOWN] until "Set Code Length" is displayed
[ENTER]
[6]
[ENTER]
Note: The code length includes the digit 0, which is always the last digit in a code.
Important:
Setting the code length to 5 digits will result in reducing the number of valid codes
stored in memory from 5000 to 3000. This is necessary since there is a limited number
of 5 digit codes. If there are already more than 3000 codes in memory, you must delete
enough old codes to reduce the number in memory to fewer than 3000 or delete all
valid codes.
4.1.5 Disable Cashier Keys
This command allows you to disable specific cashier keys. If a key is disabled, it cannot be sold
as part of a customer transaction. All cashier keys for features that are not available on the
particular carwash installation should be disabled. This prevents a cashier from selling features
that are not available and is critical if you have the automatic buy up feature that allows
customers to upgrade or pay cash for a wash at the carwash entrance.
To select this command, scroll through the system configuration secondary menu until "Disable
Cashier Key" is display and press the [ENTER] key. Once selected you will be prompted Press
Cashier Keys to Disable, Then ENTER. Press all cashier keys that should be disabled and then
press the [ENTER] key. To enable all cashier keys, press only the [ENTER] key.
