Chapter 1
An Industry-Proven Design
Industrial applications require controllers with high-vibration specifications and a wide
temperature range. Controllers in industrial environments require flexible and stable
mounting, and many machine builders underestimate the need for rugged controllers
because their applications are mounted in an industrial enclosure. UNO-4673A/4683
series has a special design without the weaknesses of a standard PC. No fan, and no
HDD prevent dust and vibration problems. With a smart mechanical design, UNO4673A/4683 series can meet 50 G shock (with CompactFlash), 2 G vibration (with
CompactFlash), up to 70°C operating temperature (tested under 100% CPU loading)
and almost anything an industrial environments demand.

two ports might be named as COM3 and COM4 in Windows. The function will not be affected and user can also change the name in the Windows Device Manager easily.
2.4.1 OXuPCI952 UARTs with 128 bytes FIFO
Advantech UNO-4673A/4683 series comes with Oxford OXuPCI952 UARTs containing 128 bytes FIFOs.
2.4.2 RS-422/485 Detection
In RS-422/485 mode, UNO-4673A/4683 series automatically detects signals to
match RS-422 or RS-485 networks. (No jumper change required)
2.4.3 Automatic Data Flow Control Function for RS-485
In RS-485 mode, UNO-4673A/4683 series automatically detects the direction of
incoming data and switches its transmission direction accordingly. So no handshaking signal (e.g. RTS signal) is necessary. This lets you conveniently 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 modification.

2.4.7 Redundant RS-422 Matter
In the occasion that UNO-4673A/4683 series RS-422 ports need to act as multi-master in parallel with other RS-422 master ports. Because of the auto detection function,
the TX port will also receive data from other RS-422 master. To avoid this situation in
this kind of application, user can use SW5and SW7 to turn it off, then no data will be
received from TX port. Please refer to the Table 2.11 for the COM port mapping and
refer to Figure 2.3 for the location.
