Figure 3-41 External Control Signal Wiring
The FT68200 series load provides an external control signal port on its rear panel. This
port receives TTL level signal, low level is effective, and its filtering time is about 20ms.
There are 3 ways to use the external control signal:
 Trigger: Used as a trigger signal by default. The input port detects a valid
low-level pulse, that is, a trigger signal is received. In dynamic PULS mode and
dynamic TOGG mode, the trigger signal can switch the load current; in the
automatic test function, the trigger signal can switch the running step to the next
step;
 Toggle: As the input switch control signal. The input port detects a valid low-level
pulse, that is, the input switch is switched once, which has the same effect as the
button;
 Hold: as the input switch control signal. When the input port detects a valid low
level, the load input is turned on, and when a valid high level is detected, the load
input is turned off.
