3.6 HOW TO GET A SINGLE PARAMETER FROM AN ID-NET™ SLAVE
READER
The current value of a single parameter of an ID-NET™ Slave (Multidata) #N can be
obtained through the Master (Multidata) device "encapsulating" the same Host Mode Get
Commands and Get Strings as a Standalone reader, (see par. 3.3), in a special command
with the following format:
<ESC> ( <B0
H
> ADDR STRING ) <ESC>
Where:
ADDR
:
Device Address
STRING
:
Get Command/String To Send (Length: 1 to 252)
ADDR
is a character indicating address of the device in an ID-NET™ Master/Slave reading
system layout:
ADDR = <30
H
> + <Device Address>
where:
Device Address = 0:
Standalone device or Master Multidata ID-NET™ device
Device Address = 1 to 31:
Slave Multidata ID-NET™ device
This means:
ADDR = <30
H
>
:
Standalone device or Master Multidata ID-NET™ device
ADDR = <31
H
> to <4F
H
>
:
Slave Multidata ID-NET™ device
The following command must be transmitted after sending each get command string:
<ESC> ( <B0
H
> ADDR <ESC> I D #) <ESC>
If the sequence is correct, the device replies with the programming string for the current
value of the parameter:
Parameter Depth = 1
<ESC> CHR1 CHR2 DATA <ESC> I A #
Where:
CHR1
:
Character identifying the category of the parameter to get.
CHR2
:
Character identifying the Function in the category.
DATA
:
Character or string indicating the current parameter Value.
