CHAPTER 2 2 Hardware Functionality This chapter shows how to set up the UNO-2050G’s hardware functions, including connecting peripherals, switches and indicators.
2.1 UNO-2050G Peripherals The following two figures show the connectors on UNO-2050G. The following sections give you detail information about function of each peripheral. Figure 2.1: UNO-2050G Front Panel Figure 2.2: UNO-2050G Rear Panel 2.2 COM1 & 2: RS-232 Interfaces The UNO-2050G offers two standard RS-232 serial communication interface ports, and they are COM1 and COM2. Please refer to A.2 for its pin assignments. 2.
16C954 UARTs with 128-byte Standard Advantech UNO-2050G comes standard with Oxford OX16PCI964 UARTs containing 128 bytes FIFOs. These upgraded FIFOs greatly reduce CPU overhead and are an ideal choice for heavy multitasking environments. Automatic Data Flow Control Function for RS-485 In RS-485 mode, UNO-2050G automatically senses the direction of incoming data and switches its transmission direction accordingly. Therefore no handshaking signal (e.g. RTS signal) is necessary.
Table 2.2: Digital Input Signal Description Signal Name Reference Direction Description DI <0...7> COM Input Isolated digital input signals COM - Input External common input of DI Isolated Inputs Each of isolated digital input channels accepts 10 ~ 50 VDC voltage inputs, and accepts bi-directional input. It means that you can apply positive or negative voltage to an isolated input pin (Vin). All eight channels share one common pin (COM).
Interrupt Function of the DI Signals DI0 and DI1 can be used to generate hardware interrupts. A user can setup the configuration of interrupts by programming the interrupt control register. The channels are connected to the interrupt circuitry. Users can disable/ enable interrupt function, select trigger type or latch the port data by setting the Interrupt Control Register of the UNO-2050G.
Interrupt Enable Control Function The user can choose to enable or disable the interrupt function by writing its corresponding value to the interrupt disable/enable control bit in the interrupt control register, as shown in Table 2-4 Table 2.4: Interrupt Disable/Enable C.
2.5 Onboard Isolated Digital Output The UNO-2050G has 8 isolated digital output channels designated DO0~DO7. Pin Assignment COM D07 D06 D05 D04 D03 D02 D01 D00 GND The connector type of UNO-2050G is plug-in screw terminal block that enables you to connect to field I/O devices directly without additional accessories. Figure 2-5 and Table 2-7 shows its pin assignment as well as signal description. Isoated DO Figure 2.5: Digital Output Connector Pin Assigns Table 2.
Table 2.8: JP12 DO Power On Configuration JP12 Power on Configuration after Hot Reset Default configuration Keep last status after hot reset Isolated Outputs Each of isolated output channels comes equipped with a Darlington transistor. All eight output channels share common collectors and integral suppression diodes for inductive loads.
2.6 Onboard Isolated Counter/Timer The UNO-2050G uses one 82C54 programmable timer/counter chip that includes three independent 16-bit down counters: counter 0, counter 1 and counter 2. Counter 0 and counter 1 are for users, and counter 2 is specified for the system and can’t be used by user. Each counter has clock input, gate input and pulse output. They can be programmed to count from 2 up to 65535 or cascaded into one 32-bit counter.
Counter/Timer Control Register The Counter/Timer Control Register controls the function and status of each counter/timer signal source. Table 2-9 shows the bit map of the Counter/Timer Control Register. The register is readable/writable register. While being written, it is used as a control register; and while being read, it is used as a status register Table 2.
Counter 0 Function Block CTR0GateSet DI4 CTR0OutSet CTR0OutSet=1 Output to DO6 CTR0GateSet=1 Out Gate CTR0Gate CTR0OUT CTR0GateSet=0 CTR0CLKSet DI6 DO6 CTR0OutSet=0 Disable CTR0IntSet Counter 0 CTR0OutSet=0 Diable Interrupt CTR0CLKSet=1 Interrupt Circuit CLK CTR0OutSet=1 Enable Interrupt 100KHz 10KHz 1KHz 100Hz CTR0F CTR0CLKSet=0 S1 S0 Figure 2.
32-bit Counter Function Block (CTR32Set=1) CTR1GateSet DI5 CTR1OutSet CTR1OutSet=1 Output to DO6 CTR1GateSet=1 CTR1Gate CTR1OUT CTR1GateSet=0 Cascaded 32-bit Counter CTR1CLKSet DI7 DO7 CTR1OutSet=0 Disable Out Gate CTR1IntSet CTR1OutSet=0 Diable Interrupt CTR1CLKSet=1 Interrupt Circuit CLK CTR1OutSet=1 Enable Interrupt 100KHz 10KHz 1KHz 100Hz CTR1F CTR1CLKSet=0 S1S0 Figure 2.
Counter Gate Source The gate sources you select determine what kind of gate input signal to enable your counter/timer when receiving clock input. There are two gate sources available for the user counters by setting gate source control bits CTR0GateSet and CTR1GateSet. Table 2.
Counter Interrupt Flag The interrupt flag bit is a flag indicating the status of an interrupt. It is a readable/writable bit. To find the status of the interrupt, you have to read the bit value; to clear the interrupt, you have to write “1” to this bit. This bit must first be cleared to service the next coming interrupt. Besides, you can choose if counter 0 or counter 1 generate interrupt signal by configuring “CTR0IntSet” and “CTR1IntSet” control bit. Table 2.
2.8 Power Connector The UNO-2050G comes with a Phoenix connector that carries 9 ~ 30 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 A.5 for its pin assignments. 2.9 LED Indicators There are two LEDs on the UNO-2050G front panel for indicating system status: PWR LED is for power status and IDE LED is for IDE bus status. 2.

CHAPTER 3 2 Initial Setup This chapter shows how to initial the UNO-2050G, sections include:.
Chapter 3 Initial Setup 3.1 Insert CompactFlash Card The procedure for installing a CompactFlash card into the UNO-2050G is as follows, please follows these steps carefully. Step 1: Remove power cord. Step 2: Unscrew four screws from the rear panel of the UNO-2050G. Step 3: Remove the rear panel. Step 4: Plug a CompactFlash card with user’s OS and application program into a CompactFlash card slot on board. Step 5: Screw back the rear panel with four screws. 3.
3.3 Connect the Power Connect the UNO-2050G to a 9 ~ 30 VDC power source. The power source can either be from a power adapter or an in-house power source. 3.4 Wiring Considerations There are several I/O interfaces use a plug-in screw terminal block for the interface between I/O modules and field devices. The following information must be considered when connecting electrical devices to I/O modules. 1. The terminal block accepts wires from 0.5 mm to 2.5 mm. 2. Always use a continuous length of wire.
3.6 HDD Extension Flexibility Although UNO-2050G is an embedded platform, there is reserve flexibility to install one 2.5” HDD. Some customers want to install a popular operating system, like Windows 2000/XP or need for larger data storage capability. UNO-2050G is also an ideal platform for applications with HDD demand. Please contact Advantech to purchase UNO-2050G's HDD extension kit.
APPENDIX A 2 Pin Assignments This appendix gives the UNO-2050G pin assignments.
Appendix A Pin Assignments A.1 Board Connector and Jumpers There are connectors and jumpers on the UNO-2050G board. The following sections tell you how to configure the UNO-2050G hardware setting. Figure A-1 and figure A-2 show the locations of UNO-2050G connectors and jumpers. Figure A.1: Connector & Jumper Locations (Top) Figure A.

Jumper Setting for RS-422/485 Interface: (Default Setting) Jumper Setting for RS-232 Interface: RS-485 Auto Flow Control & RS-422 Master/Slave Mode Selection You set the “Auto Flow Control” mode of RS-485 or “Master/Slave” mode of RS-422 by using SW1 DIP switches for each RS-422/485 port. In RS-485, if the switche is set to "Auto", the driver automatically senses the direction of the data flow and switches the direction of transmission. No handshaking is necessary.
Terminator Resistors Setup for RS-422/485 The 120W terminal resistors for impedance matching on the UNO-2050G are installed on board by selecting jumper JP7. Each terminal resistor corresponds to different channels for RS-422/485 signal lines. 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. Table A.
RS-485 Signal Wiring The RS-485 standard supports half-duplex communication. This means that just two wires are needed to both transmit and receive data. Handshaking signals (such as RTS, Request To Send) in RS-232 are normally used to control the direction of the data flow and to switch the transmission accordingly. In RS-485 mode, the UNO-2050G automatically senses the direction of the data flow and switches the transmission direction - no handshaking is necessary.
