MATRIX 210™ HOST MODE PROGRAMMING

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™ (Multidata) Slave #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 follo

wing format:

<ESC> ( <B0

> 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

> + <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

>: Standalone device or Master Multidata ID-NET™ device

ADDR = <31

> to <4F

>: Slave Multidata ID-NET™ device

The following command must be transmitted after sending each get command string:

<ESC> ( <B0

> 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.
