* ... If the e.bloxx modules are used together with an e.gate, which is used to collect the data of all connected e.bloxx
modules and processes them for fast transmission via the further network, a bus termination must be connected to the
last e.bloxx in each bus line.
Bus Connection to PC
The bus interface of the e.bloxx is based on the RS-485 standard. Since most hosts are "only" equipped with RS 232
interfaces, an interface converter or a plug-in board with RS-485 drivers is required for conversion purposes.
Gantner Instruments Test & Measurement GMBH offers a compact interface converter, called ISK 200, with an inte-
grated power supply and automatic baud rate detection. The power supply, bus connection and a separate 24 VDC-
output are DC-isolated. Therefore, the interface converter ISK 200 is also applicable as a power supply for remote
applications. Additionally, the interface converter ISK 200 features the option of connecting the required bus termination
via a switch. The converter is designed to be used as a desk device.
Another module IRK 100 from Gantner Instruments Test & Measurement GMBH is available which may be used as an
RS 485 repeater or RS 485/RS 232 converter. The baud rate can be adjusted at the IRK 100. Also, for this module the
required bus termination may be connected with a switch. The Repeater/ Converter IRK 100 has a snap-on mounting
mechanism for the installation on standard profile rails (DIN rail) 35 mm according to DIN EN 50022.
