CAES ULTRA Machine Control ; Guidance Products Computer Aided Earthmoving System Caterpillar

The tables within this section describe the keys that are used in the keypad configuration file. All of these keys relate to switch input handling, rather than to keypad handling.

Similar keys are used in order to configure switch inputs for the Navigator display. However, the switch configuration keys for a Navigator display must be entered in the machine configuration file. The keypad configuration file is used exclusively for the CD1040 display.

When CAESultra is started, a keypad application on the CD1040 also starts. The keypad application translates the keypad button selections into various commands for CAESultra and, when using a CD1040 display, also translates switch inputs for CAESultra. The keypad configuration file that is used for these translations is named "keypad.ini" and is located on the display's D: drive.

Until the release of CAESultra version 2003.1.0, the syntax for the switch configuration keys in the machine configuration file was the same as that for the keypad.ini file. After the release of CAESultra version 2003.1.0, the keys were modified to reflect the syntax of the keys in the machine configuration file.

Reference: For additional information on the switch configuration keys, refer to Systems Operation, "Machine Configuration File". For additional information on switches, refer to Systems Operation, "Switches".

Table 1

Key	Description
$revb	Configures the keypad in reverse order.
$debounceOn	Sets the debounce time for the activation of a switch
$debounceOff	Sets the debounce time for the deactivation of a switch
$minRepeatRate	Set the minimum repeat rate for a switch
$switchType	Specifies the switch type as normally open or normally closed

Table 2

$revb
Description:	Configures the keypad in reverse order This key is necessary for older CD1040s only. No production CD1040 units require this key.
Syntax:	$revb =<flag>
Example:	$revb =1 The buttons on the keypad are configured in reverse order
Parameter	Description	Possible Values	Default	Data Type	Units
flag	Reverse keypad buttons order flag	0 = Normal order 1 = Reverse order	0	Integer	NA

Table 3

$debounceOn
Description:	Sets the debounce time for the activation of a switch in order to reduce spurious activations. The debounce time is the amount of time that the switch must be activated before the action associated with the switch is started.
Syntax:	$debounceOn<switch number> =<debounce time>
Example:	$debounceOn1 =500 The debounce time for switch 1 is set to five-hundred milliseconds.
Parameter	Description	Possible Values	Default	Data Type	Units
switch number	Configured switch	0 to 4	None	Integer	NA
debounce time	Debounce time	0 to 65535	300	Integer	Milliseconds

Table 4

$debounceOff
Description:	Sets the debounce time for the deactivation of a switch in order to reduce spurious deactivations. The debounce time is the amount of time that the switch must be deactivated before the action associated with the switch is started.
Syntax:	$debounceOff<switch number> =<debounce time>
Example:	$debounceOff1 = 500 The debounce time for switch 1 is set to five-hundred milliseconds.
Parameter	Description	Possible Values	Default	Data Type	Units
switch number	Configured switch	0 to 4	None	Integer	NA
debounce time	Debounce time	0 to 65535	300	Integer	Milliseconds

Table 5

$minRepeatRate
Description:	Sets the minimum time between activations (repeat rate) of a switch If a switch is activated, and then subsequently activated again before the minimum repeat rate time has expired, then the subsequent activation is ignored.
Syntax:	$minRepeatRate<switch number> =<time interval>
Example:	$minRepeatRate1 = 15000 Any activation of a switch that occurs within fifteen seconds of a previous activation of that same switch will be ignored.
Parameter	Description	Possible Values	Default	Data Type	Units
switch number	Configured switch	0 to 4	None	Integer	NA
time interval	Elapsed time between switch activations	0 to 65535	15000	Integer	Milliseconds

Table 6

$switchType
Description:	Specifies the switch type as normally open or normally closed.
Syntax:	$switchType0 =<type>
Example:	$switchType1 =NC Switch 1 is a normally closed switch.
Parameter	Description	Possible Values	Default	Data Type	Units
type	Switch type	NO = Normally open NC = Normally closed	None	String	NA
