Product warranty
Advantech warrants to you, the original purchaser, that each of its
products will be free from defects in materials and workmanship for
one year from the date of purchase.
This warranty does not apply to any products that have been repaired
or altered by persons other than repair personnel authorized by
Advantech, or which have been subject to misuse, abuse, accident or
improper installation. Advantech assumes no liability under the terms
of this warranty as a consequence of such events.
Because of Advantech high quality-control standards and rigorous
testing, most of our customers never need to use our repair service. If
an Advantech product is defective, it will be repaired or replaced at no
charge during the warranty period. For out-of-warranty repairs, you
will be billed according to the cost of replacement materials, service
time and freight. Please consult your dealer for more details. If you
think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For
example, CPU speed, Advantech products used, other hardware and
software used, etc.) Note anything abnormal and list any on-screen
messages you get when the problem occurs.
2. Call your dealer and describe the problem. Please have your manual,
product, and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return
merchandize authorization) number from your dealer. This allows us
to process your return more quickly.
4. Carefully pack the defective product, a fully completed Repair and
Replacement Order Card and a photocopy proof of purchase date
(such as your sales receipt) in a shippable container. A product
returned without proof of the purchase date is not eligible for
warranty service.
5. Write the RMA number visibly on the outside of the package and
ship it prepaid to your dealer.

1.3 Safety Precautions
The following sections tell how to make each connection. In most
cases, you will simply need to connect a standard cable. All of the
connector pin assignments are shown in Appendix A.
Warning! Alwaysdisconnect the power cord from your chassis
wheneveryou areworkingon it.Do not connectwhile
thepower is on. Asudden rush of powercandamage
sensitiveelectronic components.Only experienced
electronics personnel should open the chassis.
Caution! Alwaysground yourself toremoveany static electric
chargebefore touchingUNO-2050. Modernelectronic
devices are very sensitive to static electric charges.
Use a grounding wrist strap at all times. Place all
electronic components on a static-dissipative surface
or in a static-shielded bag..

2.1 UNO-2050 Peripherals
The following two figures show the connectors on UNO-2050. The
following sections give you detail information about function of each
peripheral.
Figure 2-1: UNO-2050 front panel
Figure 2-2: UNO-2050 rear panel
2.2 COM1 ~ COM2: RS-232 Interfaces
TheUNO-2050 offers two standard RS-232 serial communication
interface ports, and they are COM1 and COM2. Please refer to A.2 for
its pin assignments.

Chapter 2 Hardware Functionality 11
2.3 COM3 ~ COM4: Isolated 5-wire RS-232/
422/485 Interfaces
TheUNO-2050 offerstwo isolated5-wire RS-232/422/485serial
communication interface ports, and they are COM3 and COM4. The
connector type of COM3 and COM4 is screw-terminal block that it’s
easy for wiring without additional daughter board. Each port can be
configuredindividually to either RS-232,RS-422 or RS-485by using
on-board jumpers (see Appendix A.3), and Table 2-1 lists the default
setting of each port.
Table 2-1: Serial ports default setting
16C954 UARTs with 128-byte standard
AdvantechUNO-2050 comes standard with OxfordOX16PCI964
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-2050 automatically senses the direction of
incoming data and switches its transmission direction accordingly.
Therefore 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
formodification.
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.

COM3 RS-485
COM4 RS-485

2.4 On-board Isolated Digital Input
The UNO-2050 has 8 isolated digital input channels designated
DI0~DI7.
Pin Assignment
The connector type of UNO-2050 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.
Figure 2-3: Digital input connector pin assignments
Table 2-2: Digital input connector 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
positive 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-2050’s isolated
input channels.
