2. Enable the trigger output function of Power Supply 1; and enable the trigger

input function of Power Supply 2 and 3.

3. Press On/Off on Power Supply 1 to turn on its channel output. At this time,

 As the trigger output function of Power Supply 1 is enabled, Power Supply 1

will output the trigger output signal (a high level signal, ≥2.1 V, 10 mA)

from Pin 7.

 As the trigger input functions of Power Supply 2 and 3 have been enabled,

after Power Supply 2 and 3 receives trigger input signal (i.e. trigger output

signals of Power Supply 1), the channel output will be turned on.

Similarly, when you press On/Off on Power Supply 1 to turn off its channel

output, the channel output of Power Supply 2 and 3 will also be turned off.

Now, the operation is complete. You can press On/Off on Power Supply 1 to

synchronously control the output of Power Supply 1, 2, and 3.

Mode 2:

Take the trigger output signal of one power supply as the trigger input signal of its

adjacent power supply in sequence. In this case, you can press On/Off on the first

power supply to synchronously control the output of all the power supplies. The

following example illustrates the operation steps on how to synchronously control the

other two power supplies through one power supply.

Operation Procedures:

1. Connect Pin 7 (trigger output signal) of the RS232 interface on the rear panel of

Power Supply 1 to Pin 8 (trigger input signal) of the RS232 interface on the rear

panel of Power Supply 2, and connect Pin 7 (trigger output signal) of the RS232

interface on the rear panel of Power Supply 2 to Pin 8 (trigger input signal) of

the RS232 interface on the rear panel of Power Supply 3, as shown in the figure

below.
