$AA0L

 

Name

Read Minimum Input Signal Width at Low Level command

Description

Read the minimum input signal width at low level for a

 

specified counter/frequency module to filter noise.

Syntax

$AA0L(cr)

 

$ is a delimiter character.

 

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

 

address that you will access to.

 

0L is the Read Minimum Input Signal Width at Low Level

 

command.

 

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

Response

!AA(data)(cr) if the command is valid.

 

?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.

 

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

 

μsec (microsecond) and its resolution is 1 μsec. The format

 

is a five digit integer that ranges from 2 μsec to 65535 μsec.

 

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

Example

command: $050L(cr)

 

response: !0500084(cr)

 

The command requests the counter/frequency module at

 

address 05 to read its minimum input signal width at low

 

level. The module replies that its minimum input signal

 

width at low level is 84 μsec.
