INSTRUCTION MANUAL

1 GENERAL

1.1 Description

The S2000-USB, USB-to-RS485 Interface Converter is designed to convert USB interface
signals to signals of two-wire trunk interface RS-485 with galvanic isolation. The S2000-USB is
powered via a USB port of a personal computer (PC). The S2000-USB operates with such
operating systems as Windows 2000, 2003, XP, Vista forming a virtual COM port. The S2000­USB is designed for round-the-clock operation.

1.4 S2000-USB Operation Principle

S2000-USB operation is based on converting USB interface signals to the RS-485
interface signals and back. After connecting the S2000-USB to a PC and installing the software
the interface converter is ‘seen’ as an additional COM port providing data transmission in the
half-duplex mode. Parameters of transmitting data over the RS-485 (data transmission rate,
parity, quantity of stop bits) are adjusted by the same way as for any other COM port of the PC.

2.3 Operation of the Device

2.3.1 If the S2000-USB is the first or the last (end) device within the RS-485 interface

bus then the termination resistor of 120 Ω should be brought in the line by putting on the jumper
on the contacts which are located near the RS-485 terminal block. Otherwise, the jumper should
be put off.

2.3.2 After defining the jumper position and connecting required wires the S2000-USB

can be connected to a personal computer. READY indicator shall flash; it means that the S2000­USB is not initialized on the PC.

2.3.3 The S2000-USB to operate on your PC you should install the S2000-USB driver on

the PC. To do so, select ‘S2000-USB Driver’ in the Program Setup section on the provided
Bolid Information CD and follow the instructions.

2.3.4 After first connecting the S2000-USB to a PC the Found New Hardware Wizard

window will appear on the display. Following is the description of driver setup process for
Windows XP operating system:

• Select ‘No, not this time’ and click Next:

• Then, select ‘Install from a list of specific location’ and click Next:

4

• Next, in the window for selecting driver location select the options as shown in Figure

below and specify the path to the S2000-USB driver. Click Next:

• Then, click Continue Anyway button in the appeared window:

5

• Click Finish in the appeared window:

• Now the S2000-USB driver has been installed. READY indicator on the S2000-USB

face plate should be lit steady. After driver setup, Ports (COM&LPT) of the Device
Manager will include the ‘USB

<–>

RS-232 (COM x)’ entry where ‘х’ is the number

of the virtual COM port:

By clicking Advanced you can call the relevant window and change the number of the
COM port. Let the parameters of the virtual СОМ port be rest by default (the
parameters are adjusted by a program using this COM port).

2.3.5 Indicator Operation. The READY indicator shall be lit steady in green. USB or

RS-485 indicator’s lighting means receiving a signal from the relevant line.
