6.5 Setting parameters using the PC
Using an additional USB adaptor and the Config-equitherm software, the
EQJW 145 can be configured and parameterised using a PC. To do so, the
adaptor on the EQJW 145 should be connected to the terminals for the
Modbus communication.
Communication type Modbus RTU (CP02 = 2) is set ex works. However, the
address 255 has been set instead of a valid Modbus address in the range
1 - 247. This makes it possible to communicate with the controller using the
EQJW 145 via the Config-equitherm software, without having to set any
communication parameters on the EQJW 145 beforehand.
It is not possible to communicate with non-configured controllers if several
controllers that have not yet been configured are connected to a network. In
such cases, all except one of the controllers that have not yet been
configured have to be switched off first.
