DISPLAY CONNECTION TO CONTROL MULTIPLE UNITS
The EEA649II / EEB649II - EFA649II / EFB649II
panel provides for the command of several
units; it is possible to connect up to 30 units
which will be managed by a single remote
panel;
They must be connected in series with an in
and out connection on the boards of the
individual units;
The network is an RS485 network; Use 2-wire
shielded cable with a maximum length of 150
m;
- Carry out a layout in order to minimize the
length of the leads;
- terminate the line with the supplied 120
Ω
resistor;
- do not make "star" connections; - the
connection with the RS485 cable is polarized,
