$AA2

 

Name

Configuration Status command

Description

The command requests the return of the configuration data

 

from the counter/frequency module at address AA.

Syntax

$AA2(cr)

 

$ is a delimiter character.

 

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

 

address that you will access to.

 

2 is the Configuration Status command.

 

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

Response

!AATTCCFF (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

 

that you will access to.

 

TT (50h or 51h) represents the type of code. 50h means

 

using module as a counter. 51h means using module as a

 

frequency measurement module.

 

CC represents the baud rate code.

 

Hexadecimal value FF which also equals to an 8-bit

 

parameter represents the checksum status and frequency

 

gate time. The layout of the 8-bit parameter is shown in

 

figure 4-5. The bits are not used and are set to 0.

 

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