, alarm indicator and operator panels. The CP305 acts as the master
whenever the address is set to 1 and as CP305 slave when the address is set between 2 and 90.
The master controls the data traffic on the BMS bus.
Remote alarm indicator CP305 is to be operated as a master if
- Parameters are queried or changed.
- Certain control commands were given.
Addressing
For remote alarm indicator CP305 to function properly, it must be correctly addressed.
Terminating resistor
For correct functioning of the CP305 remote alarm indicator, its correct termination is of
fundamental importance. The first and last device on the BMS bus must be terminated with a
terminating resistor (daisy chain). If the CP305 is to be terminated, the terminating resistor is
switched on with a dip switch on the bottom of the device.
