5. If voltage output is required, proceed to step 6. Current
output calibration is complete.
6. Set desired maximum voltage output with the VOLT
ADJ potentiometer.
NOTE: The device calibrates the minimum voltage
automatically according to the ratio of mA
output extremes.
Multiplexing (Q7002C
Only)
Multiplex control enables a single BAS control signal to
control up to eight Q7002C Interface Modules. Wire the
devices according to Fig. 8 or Fig. 9.
IMPORTANT
Before using a Q7002C with multiplex control, turn
on dip switch two.

a common transformer.
Fig. 9. Q7002C multiplex wiring with separate
transformers.
All devices receive all pulse signals; however, only those
devices set with a corresponding address react to the control
portion of the signal. Each signal the BAS controller sends
must include the following three pulses:
1. Attention.
2. Address.
3. Control.
Attention Pulse
The attention pulse initializes the interface modules, alerting
them that a control pulse can follow. The attention pulse is
one second longer than the existing time base.
