This manual introduces the hardware of the UC-8481 embedded computers. After a brief introduction of the hardware features, we will focus on installing and configuring the hardware.
Introduction Overview The UC-8481 uses the Intel XScale IXP435 CPU. This powerful computing engine is built around a RISC architecture, and clocks in at 533 MHz. The IXP435 runs cool, and is optimized for communication applications. The built-in 32 MB NOR Flash ROM and 512 MB SDRAM give you enough memory to directly run software applications, and a 512 MB NAND Flash is provided for data storage.

UC-8481 Series Hardware Hardware Connection Description Connecting to the Console Port The UC-8481’s console port is an RS-232 4-pin header connector. Refer to the following figure for pin assignments on the console port cable. Serial Console Port and Pinouts Serial Console Cable Signal The console port is located just below the CF card socket, on the opposite side of the motherboard.
The following description explains the installation process for CompactFlash cards. The CF is located on the motherboard beneath the cover at the back of the UC-8481. Use a screwdriver to remove the cover and access the slot. See the following figure for the locations of the CF socket.
SIM Card The UC-8481 comes with 3 SIM card sockets that users can use to install three SIM cards for cellular communications. To insert a SIM card, remove the cover at the front panel and insert the SIM card according to the specific locations.
UC-8481 Series Hardware Hardware Connection Description Digital Inputs/Outputs The UC-8481 has 4 digital outputs and 4 digital inputs. The pinouts for the I/O are shown in the following figures: Digital Input Wiring Dry Contact Wet Contact Note: If are using wet contacts, you must connect “COM” to power.
Hardware Connection Description Installing the Wireless Modules The UC-8481 comes with 1 Wi-Fi module and 1 cellular module pre-installed. However, users may add up to 1 Wi-Fi module and 2 cellular modules for further wireless connectivity. To connect further wireless modules you first need to remove the four screws on the top panel, two screws on the front panel, and two screws on the rear panel.
UC-8481 Series Hardware Hardware Connection Description Installing the Wi-Fi Module The Wi-Fi Module package includes 1 Wi-Fi module, 2 Wi-Fi antenna cables and connectors, 1 thermal pad, 5 black screws and 3 bronze screws. 1. To install the module, first find the locations of the antenna connectors and connect the antenna cables to the module.
