Introduction
SC10MK2 485 IOT 502 Modbus TCP to RTU Gateway provides easy way of connecting Modbus RTU devices to
Wireless and Ethernet LAN. The wireless supports 802.11 b/g/n in AP/Station mode with WEP/WPA/WPA2
encryption for data transmission security. The Ethernet support 10/100 Mbps auto-detecting communication
speeds. This Gateway is designed to operate 2 Serial ports (RS-232/RS-422/485 Auto detect) over Wireless and
Ethernet network. It allows users to integrate Modbus/RTU and Modbus Serial devices to the TCP/IP network
with 8 TCP Masters simultaneously and 32 requests simultaneous per TCP Master.
SC10MK2 485 IoT 502 embedded with MT7688AN MIPS chipset makes it become the ideal device for
transmitting the data from your RS-232 or RS-422/485 Serial interface devices, such as PLCs, Meters and
Sensors to an IP-based Wi-Fi and Ethernet LAN. It is a high performance design composed with carefully
selecting qualified components from reliable and certified sources. This operation manual will guide you to
configure functions step by step.

Antenna Connector
The connector for antenna is a standard reverse SMA jack. Simply connect it to a 2.0dBi dipole antenna
(Standard Rubber Duck) and it is 50 Ohms impedance and can support 2.4GHz frequency.
Ethernet Port
The connector for network is the usual RJ45. Simply connect it to your network switch or Hub. When the
connection is made, the green color LED of Ethernet port will light on. When data traffic (Rx/Tx) occurs on the
network, yellow color LED will blink during data transferring.
Serial Port of RS-232/RS-422/RS-485
Connect the serial data cable between the SC10MK2 converter and the Serial interface device. Follow the web
page parameter setup procedures to configure the converter.
