The default settings for the isolated serial ports on the ADVANTECH UNO-2050G are listed in the table below.

In RS-485 mode, the ADVANTECH UNO-2050G automatically senses the direction of incoming data and switches its transmission direction accordingly. This means no handshaking signal (like RTS) is necessary, allowing you to build an RS-485 network with just two wires. Application software previously written for half-duplex RS-232 environments can be used without modification.

The pin assignments for the plug-in screw terminal block for the 8 isolated digital input channels (DI0-DI7) are shown in the table below. Each channel accepts 10 ~ 50 VDC bi-directional inputs. All eight channels share one common pin (COM).

Note: DI4 and DI5 can be configured as Counter 0 and Counter 1’s gate control pins. DI6 and DI7 can be configured as Counter 0 and Counter 1’s clock input pins.

On the ADVANTECH UNO-2050G, digital inputs DI0 and DI1 can be used to generate hardware interrupts. You can configure these interrupts by programming the Interrupt Control Register.

Interrupt Enable Control (DIOEN & DI1EN bits):

• Writing ‘0’ disables the interrupt.

• Writing ‘1’ enables the interrupt.

Interrupt Triggering Edge Control (DIOTE & DI1TE bits):

• Writing ‘0’ sets the trigger to a falling edge.

• Writing ‘1’ sets the trigger to a rising edge.

Interrupt Flag Bit (DI0F & DI1F):

• This is a readable/writable flag. Reading the bit shows the interrupt status (0 = No interrupt, 1 = Interrupt occurred).

• To clear the interrupt, you must write a ‘1’ to this bit. The flag must be cleared to service the next incoming interrupt.

The IRQ level is set automatically by the system BIOS.

The pin assignments for the plug-in screw terminal block for the 8 isolated digital output channels (DO0-DO7) are shown in the table below.

Each channel is equipped with a Darlington transistor. If an external voltage (5 ~ 40 VDC) is applied, ensure the current through each DO pin does not exceed 200 mA.

The default configuration after power-on or a hardware reset is to set all isolated digital output channels to an open state. For a system hot reset, the status is determined by jumper JP12.

The ADVANTECH UNO-2050G has user-configurable counters (Counter 0 and Counter 1) which can be programmed via the Counter/Timer Control Register. You can configure clock sources, gate sources, output destinations, and interrupts.

Counter Clock Source: Set by CTR0CLKSet and CTR1CLKSet bits.

• 0: Internal clock (default)

• 1: External clock from digital input (DI6 for Counter 0, DI7 for Counter 1)

Counter Internal Clock: Set by S0 and S1 bits.

• S1=0, S0=0: 100 KHz (default)

• S1=0, S0=1: 10 KHz

• S1=1, S0=0: 1 KHz

• S1=1, S0=1: 100 Hz

Counter Gate Source: Set by CTR0GateSet and CTR1GateSet bits.

• 0: Gate source from “CTRxGate” control bit (Default)

• 1: Gate source from digital input (DI4 for Counter 0, DI5 for Counter 1)

Counter Output Destination: Set by CTR0OutSet and CTR1OutSet bits.

• 0: Output destination to “CTRxOut” status bit (Default)

• 1: Output destination to “CTRxOut” status bit and digital output (DO6 for Counter 0, DO7 for Counter 1)

Counter Interrupt: Enable or disable interrupts using CTR0IntSet and CTR1IntSet bits (0=Disable, 1=Enable). The interrupt flag (CTRxF) must be cleared by writing ‘1’ to it.

Cascaded 32-bit Counter: Set the CTR32Set bit to ‘1’ to cascade Counter 0 and Counter 1 into a single 32-bit counter.

The ADVANTECH UNO-2050G features a programmable LED and buzzer, which can be controlled via the LED & Buzzer Control Registers (Base+10H and Base+11H).

Programmable LED Control:

To enable LED flickering, set the LEDEn bit to 1. The flickering speed is set by the LEDS1 and LEDS0 bits:

Programmable Buzzer Control:

To enable the buzzer alarm, set the SPKEn bit to 1. The alarm type is set by the SPKS1 and SPKS0 bits:

Pressing the “RESET” button will activate a system reset function.

On the ADVANTECH UNO-2050G, you can select the interface type for the isolated serial ports (COM3 and COM4) using onboard jumpers.

To set the interface to RS-422/485 (default setting), place jumpers on all pin pairs of the corresponding jumper block (e.g., JP4 for COM3). To set the interface to RS-232, remove all jumpers from the corresponding jumper block.

You can set the “Auto Flow Control” mode for RS-485 or the “Master/Slave” mode for RS-422 on the ADVANTECH UNO-2050G using the SW1 DIP switches.

In RS-485, setting the switch to OFF (“Auto”) enables automatic sensing of data flow direction. In RS-422, setting the switch to ON makes the driver always enabled (Master mode), while OFF sets it to Slave mode.

The 120Ω terminal resistors for impedance matching on the RS-422/485 lines of the ADVANTECH UNO-2050G are enabled by selecting pins on jumper JP7. These resistors are typically needed for devices at both ends of the communication wires.

The CompactFlash interface on the ADVANTECH UNO-2050G uses a primary IDE channel. You can set it as the master or slave device by changing the setting of jumper JP3.

• Master Device (Default): Short the two pins of JP3 with a jumper cap.

• Slave Device: Remove the jumper cap from JP3.
