A9000
AC Power Source
When both front panel and remote control are idle, output of DME-A902ABT SERIES is

When user press
｢
OUT
｣
from front panel or by remote control, TTL signal has no effect
on the operation.
There are four Remote inhibit output status
：
OFF
，
LIVE
，
TRIG
，
EXCITE
。
OFF
：
Turn off remote inhibit function.
LIVE
：
two conditions
TTL signal changes from HIGH
→
LOW, and stayes low longer than 1ms,
DME-A902ABT SERIES turn off output.
TTL signal changes from LOW
→
HIGH, and stayes high longer than 1ms,
DME-A902ABS SERIES resume output.

TRIG
：
TTL signal changes from HIGH
→
LOW, and keeps low longer than 1ms, DME-
A902ABT SERIES turn off output, and stop detecting TTL signal, output stay at off state
even TTL signal changes to high. User must press
OUT
to resume output and enable
TTL signal detecting.
EXCITE
：
When user is using LIST, PULSE and STEP modes, at trigger page
（
please
refer 4.2~4.4
）
, by positive edge trigger TTL signal
（
LOW
→
HIGH
）
can trigger DME-
A902ABT SERIES output ON/OFF, pulse signal must keep at least 1ms when signal
changes
When AC source output is at turn off status, TTL signal changes from LOW
→
HIGH
will output trigger signal, there are two conditions may happen
：
If output sequences finished and TTL signal changes from LOW
→
HIGH again, will
output trigger signal again and turn on output repeat the sequences.
If TTL signal changes from LOW
→
HIGH when output sequences are not finished
yet, output will turn off.
