3.7 Setting the programmer ‘Communications Node Address’
It is possible to have up to 32 x ISPnano programmers networked together on an RS485 bus.
Each programmer must have a unique
‘Communications Node Address’
so that the PC knows
which programmer it is communicating with. This address must be in the range of 0 to 31. The
address is set by default to address ‘0’ (zero).
On the ISPnano programmer, the
‘Communications Node Address’
is stored in a location in
EEPROM and is therefore permanently remembered by the programmer even if the programmer is
power cycled. It is possible to set the
‘Communications Node Address’
to any address between 0
and 31 using the ‘
Programmer and Scripting Setup’
screen in EQTools. Setting of the address can
only be done when connected to the programmer via RS232.
To set
‘Communications Node Address’
:
•
Select either the
‘RS232-1’
or
‘RS232-2’
serial ports on the programmer.
•
Connect a serial cable from either of these serial ports to a spare PC COM port on your PC.
•
Launch EQTools
