The DIBAL D-900 scale was designed to work alone or s part of a network of MASTER and SLAVE
scales.
If operating alone, the scale must be set up as MASTER. (Follow the steps shown below to obtain this
configuration)
If the scale is set up as master, it may also be connected to a computer (which will enable it to be
programmed and managed at greater speed and reliability as well at a distance from the scale itself by
means of a modem), and it may also create a scale network.
A NETWORK of D900 scales can be made up of 1 MASTERS and 15 SLAVES depending on each
master.
Within a network of scales, each MASTER scale is assigned a number (any number between 00 and 99,
for example you can speak of master scale 02) which is known as its address: each master scale will
have one address within the network, i.e., it will be clearly addressed. Consequently, there cannot be two
or more scales with the same address.
Each of the master scales can be connected to up to 15 scales set up as slaves. A slave scale will be
assigned an address which will be a number between 1 and 15.
The slave scale whose address is 01 is called the SUBMASTER, as it automatically loads a safety copy of
all the data programmed to the master scale on which it depends.
For SAFETY reasons, THERE MUST BE A SLAVE SCALE 01 IN ALL SLAVE SUBNETWORKS: in
the case of breakdown of the master scale, by merely CHANGING THE SUBMASTER SCALE TO
MASTER you can go on working without the loss of any data.
To communicate with the computer, the group number must be defined.
To send data from the computer to the scales as well as from the scales to the computer, you need to
know which group and which master you must address. This is important when setting up the scale
network and the computer program.
