Version 1.1

Product Overview

The PPC-j1900 series PPC-J1900-121-R is a rugged, high-quality NEMA 4X/IP65-compliant industrial panel PC. It features a 12.1” resistive touch screen with a resolution of 1024 x 768 pixels.

The PPC-J1900-121-R Industrial Panel PC is powered by Intel® Celeron® J1900 quad-core CPU and equipped with a broad range of connectivity options, allowing it to meet highly demanding application requirements in harsh industrial or outdoor environments.

A specially designed magnesium-aluminum alloy housing with fins for increased heat dissipation serves as a passive cooler, eliminating the need for built-in fans. The fan-less design reduces noise, as well as the maintenance costs and efforts, increasing reliability at the same time.


Be careful when handling the product while it is operating: the back panel might become hot under heavy CPU load.

Power Input

The PPC-J1900-121-R Industrial Panel PC can be powered by a wide range of input voltages: from 9V to 30V DC. The power input connector is a 2-pin, 3.81mm screw terminal (Figure 1). The polarity of the power connector is clearly labeled on the housing itself: the ‘+’ sign is the positive, while the ‘-’ sign is the negative power supply input.

The POWER button is located next to the power input connector and can be used to switch the power ON or OFF.

The power input section of PPC-J1900-121-R features a range of protection features, including over-current, over-voltage, power surge, and reverse polarity protection, allowing it to meet stringent industrial safety regulations.

If the product is used to control some key processes, it is highly recommended to use an Uninterruptible Power Supply (UPS) to prevent critical data loss.

Touch screen

PPC-J1900-121-R is equipped with a resistive touch screen. The resistive touch screen is an ideal option for harsh industrial conditions due to its high immunity against high temperature, dirt, and dust. In addition, it does not require any special material to be operated; the resistive touch screen can be used with regular rubber gloves, fingers, or a plastic stylus.

Size/Type: 12.1” high-temperature resistant, five-wire analog resistive touch screen
Surface Hardness: 3H
Service Life (MTBF): 35 million click events
Light Transmittance: > 81%


There are many connectivity options available on the PPC-J1900-121-R industrial PC. It has 4 x USB Type A connectors configured as HOSTS, 1 x HDMI port, 2 x RJ45 connectors supporting Gigabit Ethernet (GbE), and up to 4 x RS232 connectors, of which two can be configured in the RS485 mode. There are also 8 x GPIO channels for various user-defined purposes.

RS232/485/GPIO Connectors

The PPC-J1900-121-R Industrial Panel PC has 2 x 9-pin D-sub connectors and 1 x 16-pin 3.81mm connector with pluggable terminal block (Figure 2). Two 9-pin D-sub connectors labeled as COM1 and COM2 can be configured either as RS232 or RS485 communication interfaces.

The bottom row of terminals on the terminal block is labeled as COM3/4. These terminals are configured as two additional RS232 interfaces by default. The upper row of terminals on the terminal block represents eight GPIO channels, labeled as GPIO (0 … 7).

The default configuration of the PPC-J1900-121-R industrial PC is 4 x RS232 interfaces and 8 x GPIO channels. If you need different configuration, please contact Chipsee Technical Support at support@chipsee.com

USB HOST Connectors

PPC-J1900-121-R is equipped with 3 x USB 2.0 connectors and 1 x USB 3.0 HOST connector. The USB connectors are configured as shown in Figure 3. The data throughput of the USB 3.0 interface can reach up to 4.8 Gbps, while the USB 2.0 interfaces are limited to 480 Mbps.

Although fully compatible with USB 2.0 devices, the USB 3.0 interface provides 10 times more data transfer bandwidth than USB 2.0, making it best suited for fast peripherals that can utilize its full potential.

LAN Connectors

2 x LAN (RJ45) connectors (Figure 4) provide Ethernet connectivity over standardized Ethernet cables. The integrated two-port Ethernet interface supports 10/100/1000BASE-T/TX specifications with automatic speed negotiation and Wake on LAN (WoL) functionality. Power over Ethernet (PoE) is not supported.
