$AA4

 

Name

Read Filter Status command

Description

Read the digital filter status of the addressed counter/

 

frequency module.

Syntax

$AA4(cr)

 

$ is a delimiter character.

 

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

 

address that you will access to.

 

4 is the Read Filter Status command.

 

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

Response

!AAS(cr) if the command is valid.

 

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 an invalid

 

command.

 

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

 

address of the module.

 

S is the digital filter mode.

 

S = 0 means filter is disabled

 

S = 1 means filter is enabled

 

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

Example

command: $034(cr)

 

response: !030(cr)

 

The command requests the counter/frequency module at

 

address 03 to return whether its digital filter is ON or not.

 

The module returns its address which indicates that its

 

digital filter is disabled.
