Address Pulse
The address pulse signals the modules to either accept or
ignore the control pulse. The address pulse matches one of
the existing pulses (see Table 3). If the pulse does not match
the address of a given module, that module ignores the
control pulse and continues operating according to the most
recent control pulse addressed to it.

a
The 2.65-second time base is appropriate only for multiplex operation when the BAS controller guarantees PWM output
accuracy of 0.05 second or better.
b
When shipped from the factory, the device is set to Multiplex Address 1. This is also the setting used with only one
Q7002 connected to a controller (no multiplexing).
Control Pulse
The control pulse carries the signal to adjust the control of the
addressed module. Control is based in direct proportion to the
control signal.
For Example:
A Q7002C operating with a 5.2 second time base
that received a 6.2 second attention pulse and the
proper address pulse receives a 5.2 second control
pulse. This results in module output of 100 percent. If
the same module were to receive a 2.6 second
control pulse, it would adjust the output to 50
percent.
