1. About the communication
When communication among the equipment, it becomes the method which returns the reply by receiving a
direction by this product.
Equipment (being computers such as the personal computer in this communication function) on the side
which issues this direction is called a parent machine and equipment
(being SC-380 form control board in this communication function)
The child machine sends an answer only to the inquiry from the parent machine.
For example, when wanting to take out data continuously, it makes require repeat data on the side of the
parent machine. The form of the data, the electric characteristic, the communication protocol and so on
must be each other adjusted, to communicate difference machine.
1-1. The electric characteristic
It defines the definition of the voltage level and High/Low of the signal, the airlines of the communication
and so on. This communication function is based on RS-232C which are an international standard, the
parent machine which has to do RS-232C or of RS-232C display and based a can be connected with.
1-2. The communication procedure (protocol)
The protocol to be using for this communication function is the original method of the SC-380. Because this
protocol can not be changed, make a program to agree with this protocol on the side of the parent machine.

The thread is trimmed by reverse running the motor at the set angle from the DOWN position with full
heeling or the thread trimmer signal S2. The set angle can be adjusted with the reverse run angle K8
from the DOWN position to the UP position. This can be used for blind stitch sewing machine.

ON Restart is possible for a designated time after the pedal toe down or external operation signal (S0,
S1) is turned ON immediately after full pedal heeling. This is used with a sewing machine that does
not have thread trimming.
OF Restart is not possible. Restart is possible if the pedal toe down or external run signal (S0,S1) is
turned ON again after a set time is passed.
The thread trimming timing for each manufacturer’s thread trimming sewing machine can be set.

This releases the restart operation prohibit command during thread trimming.

No operation.
The presser foot lifting operation after needle lifting is entered.
The speed setting is set so that the normal sewing machine shaft speed is constant, but by the [ON]
setting, it is possible to operate at the value which was set by the [MR], [SR] function.
This is effective when the motor pulley diameter is small, the V belt slips and the sewing machine
speed is unstable.
Set the diameter of motor pulley
When “PL” is “ON”, this function is valid.
Set the diameter of sewing machine pulley
When “PL” is “ON”, this function is valid.

** The “t” time can set when S-character cushion is set to [ON].

Speed

ON The speed change curve is accelerated slowly for the t time after pedal toe down or the external run
OF signal (S1) is turned ON, and then the sewing machine accelerates rapidly and enters the high
speed operation.
This is effective when carrying out one stitch sewing with the external run signal (S1) when automatic
operation function is set in the P mode.

** The deceleration time for the sewing machine to stop after returning to neutral from pedal toe down
or when the external run signal (S1) is turned OFF can be set. This is valid when the deceleration
time simple setting DC is set to [–].
Normally use this at 350 milliseconds or less.

ON If the pedal is toed down or external output signal (S2) is turned ON during the wiper output time [W2]
OF (after thread trimming interlock time),the wiper output time [W] will turn OFF.
The presser foot lifting output (FU) will also turn OFF simultaneously, and the sewing machine will
run after the [FD] time.
Use this for the air type wiper. This is effective for standing operation (automatic machine operation).

ON Cannot be used.
OF

ON When reverse needle lift after thread trimming RU is ON and RUS is ON, the delay time before the
OF motor reverse run after thread trimming can be set in 2 msec intervals.

*** The motor stop time before thread trimming during lock stitch can be set in 2 msec intervals. The
output R output time during chain stitch can be set in 2 msec.
When the chain stitch mode is set, it is possible to set to the delay time of the motor “R3”. Please refer
to “12 .1) Thread trimming timing when thread trimming mode TR setting is PRG” about the delay
time setting.
ON Delay time before reverse run (RU operation) after thread trimming is completed can be set with RT
OF when the thread trimming reverse needle lift RU is set to ON.

ON After the motor stops, it will start rotating after the thread trimming output T turns ON and the delay
OF time has passed. The delay time can be set by the [TD] function.

*** The interlock time that prohibits operation during thread trimming can be set.
Manual calculation will be used during the [P] mode thread trimming (TR) timing [PRG] ,[KA3], [KA4],
[KB3], [KB4], so the setting is valid.
[KA1], [KA2], [KB1], [KB2] are for automatic calculation and cannot be set.
*** The interlock time during the no thread trimming timing can be set.This is valid when the [P] mode
thread trimming timing [NO] or thread trimming release signal (TL) is turned ON.

*** When the thread trimming mode TR is set to [PRG], the output start time for the presser foot lifting
output (FU) is set.
Set according to the presser foot lifting output (FU) timing chart.
*** The time for the motor to start driving after the presser foot output FU is turned OFF when pedal toe
down or external run signal (S0,S1) ON during presser foot lifting can be set in 2 millisecond units.

When changing the input/output, set the output side to [NO] to use the port for inputs and set the input side to [NO] to use the port for outputs. The default settings are
all [NO].
(For example, if the option B connector No.2 pin is to be set to input, set the OUT4, or [O4] function to [NO], and set the required input function in IN4, or [I4] function.)
The above input/output common port is connected internally, so if a function other than [NO] is set on both the input side and output side, the output side setting will

The specification

If input PSU is turned ON while the sewing machine is
running, the needle will stop at the UP position after
swing PSU stitches and thread trimming. The no. of
stitches after PSU input is set by PSU the [P] mode of
73 page.
The constant voltage power supply. DC +12 V (max.
40 mA)
If input PSD is turned ON while the sewing machine is
running, the needle will stop at the DOWN position
after swing PSD stitches and thread trimming. The no.
of stitches after PSD input is set by PSU the [P] mode
of 73 page.
The UP position is output. This can be used as the
signal for the stitch count, etc. The output voltage is
DC 12 V/5 V (max. 40 mA).
The factory setting is 5 V.
If input S0 is turned ON, the sewing machine will run at
the speed set in low speed L. (CKD is DOWN position
signal output It changes by the CKK setting of 92 page
C mode by S0 and CKD.)
It is also input/output serving port. When using as the
input, make O4 NO setting, and when using as the
output, make I4 NO setting.
OT1 output is turned ON according to each input
specifications while inputs IO1,IR1 and IS1 are ON.
This is the input for external speed command. By
applying the variable speed command voltage, the
speed that is relative to the voltage is obtained.
It is an also input/output serving port. When using as
the input, make O5 NO setting, and when using as the
output, make I5 NO setting.
If input IO1 is turned ON, output OT1 will always be
turned ON.
A DC 12 V is output (max.50 mA).This can be used as
the power source for the photoelectric switches in the
amplifier.
If input U is turned ON, the needle lift operation will
start.
NCL output is turned ON while the sewing machine is
running (including needle lifting).
It is an also input/output serving port. When using as
the input, make O7 NO setting, and when using as the
output, make I7 NO setting.
If input F is turned ON, the presser foot lifter operation
will start.
* Same function as that of No. 4 pin of sewing machine
connector.
TF output for chain stitches.
Refer to pages 55 and 109 for the output timing.

3) To use as a standing work type sewing machine.
The sewing machine can be used as a standing work type sewing machine with the four connections below
using the lever connector. However, take special care to the intrusion of noise, and use the shortest wiring
possible.
For the standing work, it is recommended to use JUKI PK75.
