Interface Converter

back to products


The network interface converter (AD-NETGW 100 GT) enables a connection to devices with serial interface vie IP-based networks (LAN). For this, the device contains a LAN connection, a RS485 interface and an AD-UART interface. An integral wide range power pack enables operation in almost all supply situations.


The AD-NETGW 100 GT makes access to measuring values and unit conditions from distant sites possible at all times. Devices can be parameterized or measuring values can be read out. For instance, this way conditions in pumping stations can be interrogated and monitored at any time. The remote maintenance of ADAMCZEWSKI devices in local networks or via the internet can be realised.

      Block and wiring diagram





    On the network side, the device has 6 freely usable TCP channels, so-called sockets. Each of these channels can be configured freely. Also, this way up to 6 simultaneous network enquiries can be processed (i.e. of Modbus-TCP masters). For each channel, port number, bridge functions and timeout can be set. The data transport path such as Modbus-TCP can be determined on RS485 modbus RTU via the bridge functions. The date interfaces work simultaneous and independent of each other. The setting up of the serial interfaces is possible in different tapes of protocol. The connection of any device with serial interface is, of course, also possible due to the transparent router function. Ready for operation is indicated by the green illuminated diode at the LAN socket when the network cable is plugged in. The device configuration is carried out via the web server integral in the device. Here, all settings can be carried out manually via one surface. Alternatively, the device can be set up with the PC software "AD-Studio" via the AD-UART interface. Apart from the protocol conversion Modbus-TCP to Modbus-RTU, a data transparent connection can also be selected. With this, any devices with the most diverse protocols can be tied to IP networks. Already at the initial commissioning via the web interface, a password for the web surface is essential. This password is activated during the initial use of the set-up surface and will be asked for again with each new session.

      Accessories (not included)

    The voltage multiplier AD-SV 1224 GL is suitable for operation with 12V supply voltages. For connection to ADAMCZEWSKI devices with AD-UART interface, an adapter cable, 6 polar on a jack, is available.
