1.4 WM4-96 IDENTIFICATION CODE AND SERIAL NUMBER

Every Carlo Gavazzi instrument is identified by means of a code stored in address 0Bh, in order to

recognise the type of the instrument via serial communication. The WM4-96 code is 0010h.

This code can be read with the following fixed frame:

Instrument code request frame (8 byte):

01h

04h

00h

0Bh

00h

01h

CRC

Instrument code answer frame (7 byte):

01h

04h

02h

00h

10h

CRC

The serial number of the instrument is stored as short (2 bytes) on location 0218h.

NOTE: all the variables in this table are contiguous. It is possible to read the whole area with a

single command sending, in the request frame, 000h as data address and 0076h as number of

words (that is 118 in decimal).

The values of the instantaneous variables are stored in the addresses from 000h to 0E7h. The data

are sent in 4-byte groups in the following order: MSB, ..., ..., LSB.
