Failure to follow these instructions can result in death, serious injury, or equipment damage. |
USB Ports (USB01, USB23, USB45, USB89, USB1011, USB1213)
The Rack iPC provides 4 USB 3.0 interface connectors, which give complete plug and play and hot swapping for up to 127 external devices. The USB interface complies with USB UHCI, Rev. 2.0. The USB interface can be disabled in the system BIOS setup. The USB connectors are used to connect any device that conforms to the USB interface. Most digital devices conform to this standard. The USB interface supports plug and play.
The Rack iPC allows users to set the USB power between +5 VSB and +5 V. When the jumper is set to +5 V (default 2-3 pin), the board does not support wake from S3 by keyboard or mouse. If you need to set as +5 Vsb, change the jumper (1-2 pin) and modify the customized BIOS at the same time.
The Rack iPC is equipped with 2 high-performance 1000 Mbit/s Ethernet LAN adapters, both of which are supported by all major network operating systems. The RJ45 jacks on the rear panel provide convenient LAN connection.
VGA/DVI-D Connector (VGA1, DVI1)
The Rack iPC includes VGA and DVI interfaces that can drive conventional VGA and DVI displays. VGA is a standard Sub-D15 connector commonly used for VGA.
This interface is used to connect Rack iPC to remote equipment, via a cable with a Sub-D9 male connector.
The Rack iPC provides a Sub-D9 connector, which offers RS-232/422/485 serial communication interface ports.
You can change the RS-422/485 communication mode from the BIOS setting: Advanced BIOS Features Setup > Super IO Configuration.
By using a long PLC cable to connect to the Rack iPC, it is possible that the cable can be at a different electrical potential than the panel, even if both are connected to ground.
The Rack iPC serial port is not isolated. The SG (signal ground) and the functional ground (FE) terminals are connected inside the panel.

oMake a direct connection between the ground connection screw and ground. oDo not connect other devices to ground through the ground connection screw of this device. oInstall all cables according to local codes and requirements. If local codes do not require grounding, follow a reliable guide such as the US national electrical code, article 800. |

NOTE: Any excessive weight or stress on communication cables may disconnect the equipment.
The Rack iPC has an external display port connector to support the display panel.
PS/2 Keyboard and Mouse Connector (KBMS1)
Two 6-pin mini-DIN connectors (KBMS1) on the motherboard provide connection to a PS/2 keyboard and a PS/2 mouse, respectively. KBMS2 is for supporting the second PS/2 keyboard and PS/2 mouse by a cable P/N 1700018699.
Serial ATA Interface (SATA1...6)
The Rack iPC features a high performance serial ATA interface (up to 300 MB/s) and serial ATA III interface (up to 600 MB/s) which eases hard drive wiring with thin, space-saving cables.
The Rack iPC provides a PCIe x4 slot, a PCIe x16 slot and 2 PCI slots for users to install add-on cards when their applications require higher graphic performance than the embedded graphics controller CPU can provide.
