Slave Configuration
When configuring a master/slave system, each slave unit must have its bit identifier set in order to
communicate correctly with the master. On the rear panel of each slave unit there is a set of DIP
switches that must be set to a proper number. These are referred to as the Slave Bit Identifier
Switches (refer to Figure 17). The switch on each slave unit must be set to a slave ID number.
Starting at 1 set each sequential slave to the next number.
IMPORTANT:
You must be sure that no two slaves are set to the same number. Having two
slaves set to the same number will confuse the master and it will not identify
the second slave unit.
Figure 17. Slave Bit Identifier Switches
The master unit will detect all slaves present and self configure to reflect the full system rating.
The master will report all system conditions, that is: current and power levels and all alarms
including slave alarm status.
Not all slaves need to be used in order to operate. If a slave is turned off, the master detects this
and configures based on the number of slaves. Pressing the “ slave” button on the master will
display the number of slave units detected in the system.
