1. General Description NetLink is an Ethernet – Serial radio bridge that can be used as a replacement for the cable for long distance connection. It allows devices with serial / Ethernet port to communicate between each other wirelessly up to 1 km. At the same time, it also allows the conversion between different communication channels. Thanks to the point-to-multipoint configuration, NetLink allows users to create a real data collection network that is quick and easy to install. NetLink can be purchased in the following versions. Single product: Data can be transferred from Ethernet to...

3. Quick Start 3.1 Power supply Connect NetLink to a 10-30 VDC power supply (Fig.1). N.B. NetLink is protected with polarity inversion but for correct operation the polarity must be respected. Fig. 1 Power supply connection 3.2 RS232 & RS485 serials NetLink allows you to bridge both an RS485 and an RS232 serial. The terminals for the connections of the serial ports are as in Fig. 2. Fig. 2 RS232 & RS485 serial connection 3.3 Ethernet For connection to the Ethernet network, NetLink is equipped with the RJ45 connector on the front panel (Fig. 3). When connected to an Ethernet network, the...

The default IP address of MDB-E is 192.168.1.101. If your network is of the same IP class: 192.168.1 Fig. 4 Verifica indirizzo IP de proprio PC ..., go to paragraph 5, otherwise follow the instructions from point 4 to set the correct IP address. To identify the IP class of your network, run the IPCONFIG command from the command prompt. In Fig.4 on the side, the IP address of the PC is 192.168.1.5. It belongs to the same class / network as NetLink, as the first 3 numbers (192, 168 and 1) are the same. It is therefore possible to reach NetLink from the PC browser. If the network is NOT of the...

channel and both serial channels simultaneously. This means that devices on RS485 or a device on RS232 can be connected indiscriminately. Not at the same time. • Radio - Ethernet, serial: communication module is activated if present. It is necessary to have a pair of devices to ensure that they transmit the received packets to each other. The device equipped with the radio module is identified as NetLink. • Serial-Serial: In this mode the protocol conversion is performed between the RS232 communication channel and the RS485 channel.
