1Product Introduction
1.1 Summary
The KPS310XA&320XA series Serial Server is an industrial Serial Server based on Linux
system architecture and ARM 9 processor. It is mainly used for the conversion of communication
regulations. Through data acquisition, storage and control operations, it can realize online real-time
monitoring and remote control and other functions, and can be used as the terminal equipment of the
industrial Internet platform.
This Serial Server supports TCP Client, TCP Server and UDP network modes, supports
transparent transmission and Modbus RTU data transmission protocols.
The Serial Server can be divided into RS232 and RS485 two serial communication modes. The
RS-485 Serial Server provides a switchable terminal resistance of 120Ω to reduce signal reflection
and effectively improve the stability and reliability of RS-485 serial port communication.

2Electrical characteristics and specification parameters
2.1 Connect power supply
KPS310XA&320XA Serial Server is powered by the power terminal connection to the 12-48V
DC power supply.
The device operates immediately when connecting the power, and the power indicator located on the
front panel of the device shines. The device has the reverse connection protection, overload protection and
power down alarm function.
Power requirement：
Input voltage: 24V DC (12-48VDC)
Terminal block: 2-pin plug-in terminals
power：KPS3101A：1.0W

KPS3102A：1.0W
KPS3204A：1.5W
KPS3208A：1.6W
2.2 Connect serial device
The serial port of the KPS310XA&320XA Serial Server device is located on the front panel of
the device. If you are trying to connect multiple devices to the serial port, all devices must use the
same communication protocol
Pin description of serial port refer to section 2.5: pin definition.
2.2.1 RS-485 terminal resistance
When using the RS-485 transmission mode in complex industrial environments, it may need to
increase the terminal resistance and reduce the signal interference caused by serial signal reflection.
KPS310XA&320XA Serial Server serial port has the default pull-up/drop-down resistance of
1KΩ/150KΩ. For each serial port, the DIP switch on the top panel of the Serial Server device is used
to enable/disable the 120Ωterminal resistance of the RS-485.
Set 120Ω terminal resistance on KPS310XA&320XA: Identification n of the DIP switch
corresponds to the serial port Sn. When the n DIP is switched to the ON, the terminal resistance of
the corresponding Sn serial port is enabled; when the n DIP is switched to the OFF, the terminal
resistance of the corresponding Sn serial port is disabled; the terminal resistance is disabled by
default on the Serial Server device.
2.2.2 Network port
KPS3101A/KPS3102A Serial Server has 1 10/100Mbps network port; KPS3204A/ KPS3208A
Serial Server has 2 10/100Mbps network ports, it is located in the front panel of the Serial Server.
The Serial Server device can connect to the other host or network through the network port.
When working normally, the Serial Server can be connected to network by the network cable.
When initialization and fault detection are required, the Serial Server can be directly connected to PC
by the network cable. When the Serial Server is running, the green and yellow LED lamps on the
network port will light to indicate whether the Serial Server is connected to the network and the rate
of accessing the network.
KPS3101A/KPS3102A Serial Server has one IP and one MAC address; KPS3204A/KPS3208A
Serial Server has 2 IP addresses and 2 MAC addresses, the IP address can be changed by user, the
MAC address can’t be changed;
If you want to connect multiple devices to the network, the external network device must keep

the same network segment as the network port of the Serial Server and no IP, MAC address conflicts.
2.3 LED Indicator
The LED indicator of KPS310XA&320XA Serial Server is located on the front panel of device.
