A9000
AC Power Source
 When both front panel and remote control are idle, output of DME-A902ABT SERIES is
according to external TTL ON/OFF signal.
 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.

TTL
 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
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.
