ARB-0612Converter USB – RS 232/422/485/485-4W/TTLManualARB-0612_v1_01Update date:10/2018r.Symbols & Marks (3)General installation and safety rules (3)1.Destination of device (4)2.Device parameters (5)2.1.Technical parameters (5)2.2.Description of connectors (6)2.3.Block diagram (8)2.4.Dimensions (8)3.Wiring (9)4.Instalation (10)4.1.Installation of USB drivers (10)4.2.Changing the COM port assignment in Windows (11)4.3.Exploitation (14)5.Contact details (14)General installation and safety rulesThe device should be installed in accordance with this manual.The fulfillment of this condition is the basis for ensuring safety and correct operation of the device. The fulfillment of this condition is the basis for ensuring safety and correct operation of the device.The manufacturer is not liable for damages resulting from using the device in the wrong way or not according to the purpose.Modifications to the device are not allowed and can be a source of danger.The ARB-0612 converter converts the USB signal into a serial communication standard RS232/RS422/RS485,RS485-4W/TTL-3.3,TTL-5V. The device is powered directly from the USB port. The converter supports two RS485 standards (2-wire and 4-wire), can act as HUB USB to 2xRS485 2-wire.Works with32 and 64bit operating systems.Remember to use the appropriate drivers. The device is intended for the USB 2.0 standard. When connected to the 3.0 standard, the converter works as if it was connected to the standard 2.0. It is possible to choose one of four serial transmission standards, i.e. RS232, RS422, RS485 or TTL. The converter provides 1500V, 2500V, 3000V or 5000V isolation between the USB port and the other serial ports. In addition, the RS422 and RS485 port has overvoltage protection. The operating system creates a virtual COM serial port that can be used by applications as an ordinary COM port. The user has the option of assigning a different COM port number than the one that automatically assigned the system. All parameters of the COM port (for example: baudrate, parity check), are determined by the application using the converter ARB-0612.Application:–Protecting your PC or laptop from overvoltages and from damage that may occur when using serial communications.–Creating or adding an additional serial port from 1 to 256.–The RS232 port is equipped with all transmission and reception lines, which allows for safe programming of controllers and other devices requiring serial communication and using additional RS232 port signals.–The ARB-0612 converter has an internal reset signal, thus it can be used for permanent operation in applications that have the option of automatically rebuilding the serial port.2.1.Technical parametersTechnical parameters of the converter are presented in Table 2.1.1.2.2.Description of connectorsThe view of the ARB-0612 converter is shown in Figure 2.2.1. A description of its connectors is presented in Table 2.2.1. A description of the function of connectors, DB9 sockets, dip-switch and LED indicators is presented in Table 2.2.2.Fig. 2.2.1.

The method of connecting the RS ports.4.Instalation4.1.Installation of USB driversBefore you start the proper operation, you must install the appropriate USB drivers on the computer with which the converter should work. The type of drivers depends on the operating system installed on your computer.The drivers and instructions for installing them are available at: /FTDrivers.htm.To change the assignment of the COM port, it is necessary to start the Device Manager while the converter ARB-0612is connected from the USB side to the computer.Menu: Start->Control Panel->System->Hardware->Device ManagerSelect USB Serial Port whose settings you want to change.Press the right mouse button and select Properties from the expanded menu.In the Port Settings tab, please select Advanced options ...In case the selected port is already occupied by another device,the following message will appear:If you have to use this port, press YES4.3.ExploitationAfter correct installation of the drivers and connecting the converter to the USB port in the device manager should be visible COM port assigned to the converter. The device is signaled by sound and blinking of DL and UL diodes. The PWR diode should be permanently illuminated.5.Contact detailsASPAR s.c.ul.

Switching Stages
The output stages consist of NPN power transistors with open collectors. Each stage has its own protective circuit for limiting power dissipation and shorted load current, which makes the outputs shorted load protected to the supply voltage throughout the operating range. Integrated clampdiodes limit positive voltage spikes that occur when inductive loads are discharged. Output currents, caused through negative voltages at the outputs, are compensated up to 50 mA for all outputs in total.
