4080, 4080D

Digital I/O and Relay Output

Counter/Frequency Command Set

$AA0H(data)

 

Name

Set Minimum Input Signal Width at High Level command

Description

Set the minimum input signal width at high level for a

 

specified counter/frequency module to filter the noise.

Syntax

$AA0H(data)(cr)

 

$ is a delimiter character.

 

AA (range 00-FF) represents the 2-character hexadecimal

 

address that you will access to.

 

0H is the Set Minimum Input Signal Width at High Level

 

command.

 

(data) is the minimum width at high level. The unit is in

 

µsec (microseconds) and its resolution is 1 μsec. The

 

format is a five digit integer that can range from 2 μsec to

 

65535 μsec. Out of range values will cause errors.

 

(cr) is the terminating character, carriage return (0Dh).

Response

!AA(cr) if the command is valid. The addressed module

 

stores the value and will recognize the input signal “high”

 

only after the input signal continues “high” and for longer

 

than the specified value.

 

?AA(cr) if an invalid operation was entered.

 

There is no response if the module detects a syntax or

 

communication error, or even if the specified address does

 

not exist.

 

! is a delimiter character which indicates a valid command.

 

? is a delimiter character which indicates an invalid

 

command.

 

AA (range 00-FF) represents the 2-character hexadecimal

 

address of the module.

 

(cr) is the terminating character, carriage return (0Dh).

Example

command: $130H00020(cr)

 

response: !13(cr)

 

The command requests the counter/frequency module at

 

address 13 to set the minimum input width at high level to

 

20 μsec. The module stores the value and will identify an

 

input signal to be "high” only if the signal continues to be

 

“high” longer than 20 μsec. This function can be used as a

 

digital filter.
