1. Specications
The "IoT Gateway JGW-01" (hereinafter referred to as the IoT Gateway) is a WLAN (Wireless Local
Area Network) Gateway for relaying sewing machines and sensors to the production management
system.
It is connected, with cables, to the JUKI sewing machines that support serial communications, sew-
ing machines that do not support serial communication but are equipped with a main-shaft rotation
sensor, and production switches to acquire the sewing-machine operating information.
The sewing machine communicates with the production management system to send operating
information through the IoT Gateway using a WLAN.
The IoT Gateway operates by connecting it to a 12 - 24 VDC power supply.

The IoT Gateway incorporates a WLAN module to emit and receive radio waves through an anten-
na mounted on the PCB. It implements WLAN communication by using 2.4 GHz frequency band
that conforms to the wireless communication standards IEEE 802.11b/11g/11n. Do not use the IoT
Gateway at a location adjacent to a TV or radio if it causes a receiving failure or has an adverse
e󰀨ect on any other electronic equipment.

DANGER:
1. To prevent personal injuries caused by electric shock hazards or abrupt start of the
sewing machine, carry out the work after turning OFF the power switch and a lapse of 5
minutes or more.
2. To prevent accidents caused by unaccustomed work or electric shock, request the
electric expert or engineer of our dealers when adjusting the electrical components.
