munication interface ports, and they are COM3 and COM4. The connec-
tor type of COM3 and COM4 is screw-terminal block that it’s easy for
wiring without additional daughter board. Each port can be configured
individually to either RS-232, RS-422 or RS-485 by using on-board
jumpers (see Appendix A.3), and Table 2-1 lists the default setting of
each port.

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. There-
fore no handshaking signal (e.g. RTS signal) is necessary. This feature
lets you simply and quickly build an RS-485 network with just two wires.
More importantly, application software previously written for half duplex
RS-232 environments can be maintained without need for modification.
IRQ and Address Setting
The IRQ and I/O address range are both assigned by BIOS. COM3,
COM4 serial ports and on-board digital I/O use the same IRQ.
2.4 Onboard Isolated Digital Input
The UNO-2050G has 8 isolated digital input channels designated
DI0~DI7.
Pin Assignments
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 2-3 and Table 2-2 shows its pin assignment as well as
signal description.

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 posi-
tive or negative voltage to an isolated input pin (Vin). All eight channels
share one common pin (COM). Figure 2-4 shows how to connect an
external input source to one of the UNO-2050G’s isolated input channels.
Please note that DI4 and DI5 may be configured as Counter 0 and
Counter 1’s gate control pins; DI6 and DI7 may be configured as Counter
0 and Counter 1’s clock input pins. Please refer to “Section 2.6” for detail

11 Chapter2
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 set-
ting the Interrupt Control Register of the UNO-2050G. When the inter-
rupt request signals occur, then the software will service these interrupt
requests by ISR (Interrupt Service Routine). The multiple interrupt
sources provide the card with more capability and flexibility.
IRQ Level
The IRQ level is set automatically by the system BIOS. There is no need
for users to set the IRQ level. Only one IRQ level is used although it has
several interrupt sources.
Interrupt Control Register
The Interrupt Control Register controls the function and status of each
interrupt signal source. Table 2-3 shows the bit map of the Interrupt Con-
trol Register. The register is readable/writable register. While being writ-
ten, it is used as a control register; and while being read, it is used as a
status register
DI0EN & DI1EN: DI0 & DI1 Interrupt disable/enable control bit
DI0TE & DI1TE: DI0 & DI1 Interrupt triggering edge control bit

UNO-2050G User Manual 12
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
Interrupt Triggering Edge Control
The interrupt can be triggered by a rising edge or a falling edge of the
interrupt signal, as determined by the value in the interrupt triggering
edge control bit in the interrupt control register, as shown in Table 2-5.
Interrupt Flag Bit
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
