User Manual for 4 Port Modbus RTU/ASCII to Modbus TCP Gateway, SC10E4M K &SC10E4IM K
Introduction
SC10E4M K 4-Ports Modbus RTU/ASCII To Modbus TCP Gateway providing new ways of connecting
serial devices to a Wireless LAN (Wi-Fi 802.11 b/g/n ). This Gateway is designed to operate 4 serial
ports through wireless (Wi-Fi 802.11 b/g/n) over 10/100Mbps Ethernet network. As the data is
transmitted via TCP/IP protocol, data acquisition and controlling is available to go through Intranet and
Internet. 4 Serial ports operate in common RS-232, RS-422 and RS-485 auto selection modes
configuration.
SC10E4M K is 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, various
Meters and/or Sensors to an IP-based Wi-Fi LAN, and making it possible for your software to access
Serial interface devices anywhere and anytime.
SC10E4IM K provides Modbus TCP Server and Modbus TCP Client Mode for selection. It supports
manual configuration via web browser and support various protocols including TCP, IP, HTTP, DHCP,
ICMP and ARP. These are the best solution to coordinate your Serial interface devices.

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 RS232/RS422/RS485
Connect the serial data cable between the SC10E4M K Gateway and the Serial interface device.
Follow the web page parameter setup procedures to configure the Gateway.
DC-IN Power Outlet
The Serial to Ethernet +Wi-Fi Gateway is powered by a single 12V DC (Inner positive, outer negative)
power supply and 1.0mA of current. Connect the power adaptor to the AC power socket and put the
DC Jack plug into the outlet of device. The “SYS” green color LED will be ON when power is properly
