7.5 System
Modbus Address
The addresses 1 to 255 are available as identifier for
Humi
Core
™
Pro
and can
be assigned to the device by means of the PC setup program. The
Humi
Core
Pro
always has the address 1 as default value.
Baud Rate
The transfer speed of the RS-232 and RS-485 port in the
Humi
Core
Pro
is deter-
mined by the parameterizable baud rate.
The following values are available for this purpose: 2400, 4800, 9600 and 19200
bps.
Attention:
If the baud rate set as the default value at 19200 bps is changed to another value
with the help of the PC setup program, this parameter change does not take effect
in the device until after disconnection of the power supply.
Communication
The parameterization for the baud rate and the device address have to be identical on both sides in order
to start communication between PC and
Humi
Core
Pro
.
If a baud rate and/or address does not conform with the default values, this means they have to be looked
for to enable communication with the PC program and in the worst case 1020 attempts would be necessary
for this purpose (see ‘Connect configuration program’ in Section 6.3).
