Setting parameters using the PC
The EQJW 125 can be configured and parameterised with a PC using an
additional USB adaptor and the
Config-equitherm
software. To do so, the
adaptor should be connected to the terminals for Modbus communication on
the EQJW 125.
Modbus RTU (CP02 = 2) is the type of communication that has been set ex
works. However, the address 255 has been set, rather than a valid Modbus
address in the range 1 - 247. This makes it possible to communicate with the
controller via the
Config-equitherm
software without having to set
communication parameters on the EQJW 125.
It is not possible to communicate with non-configured controllers if there are
several controllers in a network that have not yet been configured. In such
cases, all but one of the controllers that have not yet been configured has to
be switched off beforehand.
