CHAPTER 2 2 Hardware Functionality This chapter shows how to setup the UNO-2174A/2178A’s hardware functions, including connecting peripherals, setting switches and indicators.
Chapter 2 Hardware Functionality 2.1 Introduction The following figures show the connectors on UNO-2174A/2178A. The following sections give you information about each peripheral. Figure 2.1: Front Panel of UNO-2174A Figure 2.2: Front Panel of UNO-2178A Figure 2.3: Rear Panel of UNO-2174A Figure 2.
2.2 UNO-2174A/2178A Interface (COM1~COM6) UNO-2174A offers two standard RS-232/485 serial communication interface ports: COM1 and COM2. Note: UNO-2178A offers additional 4 RS-232/485 COM port COM3 ~ COM6 through expansion cable connected from DB25 pin.
2.3.1 16C550 UARTs with 128-byte standard Advantech UNO-2174A/2178A comes with OXuPCI952 UARTs containing 128 bytes FIFOs. These upgraded FIFOs greatly reduce CPU overhead and are an ideal choice for heavy multitasking environments. 2.3.2 RS-422/485 detection In RS-422/485 mode, UNO-2174A/2178A automatically detects signals to match RS-422 or RS-485 networks. (No jumper change required) 2.3.
2.4 Terminal Resistor Setup for RS-422/485 The onboard termination resistor (120 Ohm) for COM1-6, COM A, and COM B can be used for long distance transmission or device matching (Default Open). Each terminal resistor responds to different channels for RS-422/485. Usually, these resistors are needed for both ends of the communication wires and the value of the resistors should match the characteristic impedance of the wires used.
2.5 RS-232/422/485 Selection COM1 to COM2 support 9-wire RS-232 and RS-485 interfaces. COM3 to COM6 (UNO-2178A) support 4 wire RS-232 and RS-485 interfaces. COM A and COM B support 9-wire RS-232/422/485 interface. The system detects RS-422 or RS-485 automatically for COM A and COM B. To select between RS-232 or RS-485 for COM1 - COM6, adjust JCOM1 to JCOM6 accordingly. For COM A and COM B the corresponding jumpers for RS-232/422/485 selection are JCOM A and JCOM B. 2.5.
Figure 2.8: RS-485 Jumper Setting (COM3-6) 2.5.
2.5.3 RS-485 Auto Flow & RS-422 Master/Slave Mode You can set the “Auto Flow Control” mode of RS-485 or “Master/Slave” mode of RS-422 by using the SW4 DIP switch for COM A and COM B.. In RS-485, if the switch is set to “Auto”, the driver automatically senses the direction of the data flow and switches the direction of transmission. No handshaking is necessary. In RS-422, if DIP switch is set to “On,” the driver is always enabled, and always in high or low status. Table 2.
2.7 Power Connector The UNO-2174A/2178A comes with a Phoenix connector that carries 9~36 VDC external power input, and features reversed wiring protection. Therefore, it will not cause any damage to the system by reversed wiring of ground line and power line. Please refer to Appendix A.6 2.8 PS/2 Keyboard and Mouse Connector The UNO-2174A/2178A provides a PS/2 keyboard and mouse connector. A 6-pin mini-DIN connector is located on the rear panel.
2.12 RTC Battery Specification UNO-2174A/2178A has RTC Battery to ensure the setting in bios and system clock can be kept, even with power disconnected for a short time. • Type: BR2032 (Using CR2032 is NOT recommended) • Output Voltage: 3 VDC • Location: BH1, please refer to below figure Figure 2.9: RTC Battery Location 2.13 Power Button / Power Management Press the "PWR" button to power on or power off UNO-2174A/2178A (ATX type).
2.14 Reset Button Press the "Reset" button to activate the hardware reset function. 2.15 HD Audio UNO-2174A/2178A is equipped with ALC892-GR which is a High Definition Audio Codec. UNO-2174A/2178AF provides 3 phone jack connector for 5.1 channel output.
