Overview
With the IC4 USB-RS485 bidirectional adapter you can create an extra serial port on
a notebook or PC and connect a serial device through a free USB port. It provides
reliable galvanic isolation between the interfaces. The device is powered directly
through the USB port.
Driver installation
When an Internet connection is available, the driver is automatically installed when
you first connect the device to the PC.
If the device should be connected to a PC without internet connection, the driver
must be installed on the PC before the device connection. The latest version of the
driver is available for download at www.akytec.de. Execute the installation file and
follow the instructions.
The connection appears in the Device Manager as a virtual COM port “CP2104 USB
to UART Bridge Controller”. The driver runs under:
– Windows XP/Vista/7/8/8.1/10
– Linux 2.6.x/3.x.x
– Mac OSX

Installation
The device is designed in a plastic enclosure for DIN rail mounting (see Fig. 1).
The device should be connected according to the diagram shown in the Fig. 2:
−Connect the USB port of the converter with the USB port of the PC
−Connect the RS485 terminals of the converter with the RS485 terminals of the
Slave device
−Twisted pair cable should be used for the connection to the RS485 network

Maintenance
The maintenance includes:
−cleaning of the housing and terminal blocks from dust, dirt and debris
−checking the fastening of the device
−checking the wiring (connecting leads, fastenings, mechanical damage)
The device should be cleaned with a damp cloth only. No abrasives or solvent-
containing cleaners may be used. When carrying out maintenance the safety infor-
mation must be observed.
Transport and storage
Pack the device in such a way as to protect it reliably against impact for storage and
transportation. The original packaging provides optimum protection.
If the device is not taken immediately after delivery into operation, it must be careful-
ly stored at a protected location. The device should not be stored in an atmosphere
with chemically active substances.
