1INTRODUCTION
The USB-COMi PRO /USB-2COMi PRO is completely jumperless and free of DIP
switches, all configuration is done by software. Just press the button and use the
configuration program.
Serial ports on USB allow further use of existing devices, even when the computer
doesn’t offer serial ports. Now the USB-COMi PRO /USB-2COMi PRO is extremely
flexible in offered communication standards. Besides the classical RS232 and RS422 it
offers three variants of the RS485 operation. The often-required Termination and
Polarization (BIAS) is also provided by built-in hardware, and it is controlled by the
same configuration software. The driver allows to configure the serial ports for bitrates
of up to 3Mbit/s. In RS232 mode the bitrate is limited to 1 Mbit/s.
Plugging the USB-COMi PRO /USB-2COMi PRO to USB port, the adapter is
automatically detected and installed. There are no IRQ & COM port conflicts, since the
port does not require any additional IRQ, DMA, memory as resources on the system.
The RS-232/422/485 port functions as native Windows COM port, and it is compatible
with Windows serial communication applications.
The USB Industrial I/O Adapter provides instant connectivity to RS-232/422/485
communication device for factory automation equipment, multi-drop data collection
devices, barcode readers, time clocks, scales, data entry terminals, PC to PC long
distance communications and serial communication in harsh environments. The USB
Industrial I/O provides industrial solution for applications requiring single node or
multi-drop communications over short and long distance.
USB-COMi PRO /USB-2COMi PRO is an innovative USB to serial converter providing the
capability of serial devices networking and sharing across any network including
Ethernet, WAN, VLAN, VPN and the Internet. The serial devices connected to the
adapter can be conveniently shared and accessed over Ethernet by multiple remote
client computers.

The left panel displays all devices detected by the search.
By clicking a port in the left panel, the operation mode is then changed by the radio
buttons and the check box in the right panel. The button to “Commit Changes”
transfers the required parameters to the selected device. They are stored in
nonvolatile RAM and activated after the transfer.

You may select several ports of one device at the same time. This is done by the usual
Windows method, i.e. clicking with Shift- or Ctrl-Key pressed. The selected
configuration then applies to all selected ports, “Commit Changes” configures all of
them at the same time. Finally, in the left panel you may select multiple devices at the
same time. The configuration then applies to all ports of all selected devices.

6PROPER WIRING FOR RS-422/485 OPERATION
This section will provide proper wiring information about RS-422 and RS-485 data
communication. It is necessary to have the basic knowledge in order to avoid or find
errors in data transmission. Failures in cabling are responsible for most transmission
problems.
6.1 RS-422 & RS-485 Transmission Technique
The RS-422 and RS-485 use the same balanced transmission method. Signals are not
transmitted as voltage on a single wire, like in RS-232. Instead, two wires are used;
when one carries high voltage, the other one carries low voltage. The signal is defined
by the difference in voltage between those two wires. This hardens the transmission
against noise. Usually twisted pair cables are used, which further reduces the
sensitivity for noise.
To make sure the signals meet the common voltage range, the GND of sender and
receiver must be connected somehow. To ensure the signals are in the valid voltage
range and the differential voltage can be correctly sensed by the receiver, the GND
lines of the transmitter and receiver must be connected.
6.2 RS-422 Signals Connected
The following diagram shows how RS-422 signals are connected.

6.3 RS-422 & RS-485 4-wire Scheme
The RS-422 requires dedicated wire pairs for transmit and receive. The transmit wires
are used to send data to as many as 10 receivers, as stated in the specifications of RS-
422. Since the USB-to-Industrial Single RS-232/422/485 Adapter uses the RS-485’s line
driver technology, up to 32 receivers are possible. The following diagram shows RS-
422 and RS-485 4-wire scheme:
