simul
R/W
integer
Simulate given number of Indoor Units. To disable simulation use
"0". Simulation is persistent (not disabled after power reset)
By default the simulation model is: with failures, no ventilation
units, no input/output units. To enable/disable special conditions
use the following flags:
+/-flr, +/-vam, +/-io (see example)
Input/Output units
for ME only
Ventilation units
for DK, ME, LG
only
myid
R/W
string
CoolMasterNet Own address on given HVAC Line.
For ModBus RTU Line myID is a "Slave Device Address"
baud
R/W
Configure UART parameters for given Line. Value format is:
<BAUD> <8|9><N|E|O><1|2>
For example: 9600 8N1
