Local Operation
1. TTL High Level Voltage is 5V
。
2. SHORT [1:10]: Short ON output signals from the first channel to the
tenth channel, TTL Level, Active High.
3. TRIG_ SEQ: External trigger input signal used to increment get to
the next sequence setting. TTL Level, falling edge, pulse width ≥1μs.
4. TRIG_DIGI: External trigger input signal to be the trigger Source of
Digitizing Function. TTL Level, falling edge, pulse width ≥1μs
5. LOAD_ON: Load ON output signal, TTL Level, Active High.
6. DI [1:2]: 2 bits of digital input signals, TTL Compatible.
DI1 and DI2 have External Load ON/OFF function. The user can use
this input signal to control the Load ON/OFF externally. If DI1 and
DI2 are set to External Load ON/OFF, the two signals need to be
HIGH to become Load OFF and vice versa both of the signals need
to be LOW to become Load ON.
When DI1 (or DI2) is set to Remote Inhibit and is Low, all channels in
FRAME are Load off and a REMOTE INHIBIT protection message
will appear. Load on will not be active if the protection message of
REMOTE INHIBIT is not cleared even though the DI1 (or DI2) is
High.
7. DO [1:2]: 2 bits of digital output signals, High Level: 4.7kΩ resistor
pull up to 1.8V/3.3V/5V selectable, Low Level <0.6V, sink current =
10mA.
DO1 and DO2 have the following 5 functions available for selection:
a. OCP TEST PASS-H: In OCP mode, if the test result is Pass, the
DO will output HIGH level signal, or it remains at LOW level.
b. OCP TEST FAIL-L: In OCP mode, if the test result is Fail, the
DO will output LOW level signal, or it remains at HIGH level.
c. GONG TOTAL PASS-H: When the SPEC is ON, if all channels
are determined as Good, the DO will output HIGH level signal,
or it will remain at LOW level.
d. GONG TOTAL FAIL-L: When the SPEC is ON, if all channels
are determined as No Good, the DO will output LOW level
signal, or it will remain at HIGH level.
e. OTP OVP OCP OPP REV-H: If the load has any one of the
OTP, OVP, OCP, OPP, REV protection, the DO will output
HIGH level signal, or it will remain at LOW level.
The selections of DOUT_VOLT are:
a. NONE: It sets the Dout High level to floating.
b. 1.8V: It sets the Dout High level to 1.8V.
c. 3.3V: It sets the Dout High level to 3.3V.
