Introduction
The PS2121 series print server is designed with a high-performance 32-bit network communication processor and an embedded real-time operating system. It facilitates printer sharing for multiple users, supporting up to two printers simultaneously. It features two Ethernet RJ45 interfaces and WiFi capability.

Industrial Design
The device is equipped with a high-performance industrial-grade 32-bit MIPS processor, ensuring low power consumption, minimal heat generation, fast processing speed, and high stability. It supports automatic restart or reconnection when disconnected and can be installed using hanging ear installation. The shell is made of sheet metal cold-rolled steel, and it operates on a power supply of 7.5V to 32V DC.

Features
The print server provides two USB ports for connecting two printers simultaneously and supports both WiFi client and AP modes. It allows cross-network segment printing, print queue management, U disk sharing, scanning, scheduled restarts, and DHCP. The device can switch between 1 WAN and 1 LAN or 2 LAN configurations.

WiFi Parameters
The server supports IEEE802.11b/g/n standards with security encryption methods including WEP, WPA, and WPA2. It has a transmit power of 16-17dBm for 11g, 18-20dBm for 11b, and 15dBm for 11n, with a receiving sensitivity of less than -72dBm at 54Mbps.

Interface Type
The device includes 1 LAN port and 1 WAN port, both adaptive MDI/MDIX with built-in electromagnetic isolation protection, and 2 USB interfaces. It features indicators for power, WAN, LAN, WiFi, and link status.

Specifications
The print server is housed in a plate metal cold-rolled steel shell, measuring 97×67×25mm and weighing approximately 185g. It operates with a CPU speed of 650MHz, 16MB Flash, and 128MB RAM. The working temperature range is -30 to 70°C, with a storage temperature range of -40 to 85°C and relative humidity of less than 95% non-condensing.

Networking and Power
The device includes a standard SMA WiFi antenna interface with a characteristic impedance of 50 ohms and a power interface supporting 7.5V to 32V with built-in overvoltage protection. A reset button allows restoration to factory settings by pressing for 10 seconds.
