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.

DO [1:2]: 2 bits of digital output signals, High Level: 4.7k
Ω 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.
d. 5.0V: It sets the Dout High level to 5.0V.
8.
DGNDC: Digital signal reference ground.
9.
EXT_WAVE [1:4]: External wave input signals from the first channel
to the fourth channel, the input range is from 0 to 10V.
10. VMON [1:4]: Voltage monitor output signals from the first channel to
the fourth channel, the output range is from 0 to 10V.
11. IMON [1:4]: Current monitor output signals from the first channel to
the fourth channel, the output range is from 0 to 10V.
12. AGNDC: Analog signal reference ground.
The System I/O port on the rear panel of the 63600-1 mainframe is a 15-pin connector (D-
SUB 15 pins male connector). It includes 0-10VDC analog signals to monitor voltage and
current, external analog signal input and digital I/O signals. The digital system I/O signals are
TTL compatible. Definitions are as follows:
