Application notes overview - IP serial
Many simple IT devices offer only a serial interface for local data handling and capture. With IP serial converters, remote data capture and system control via Ethernet, both LAN and WAN networks, can be easily implemented.
Controlling of IP Relay using program NetCat
Besides the RS-232 serial port, the IP Relay device contains also another two relays whose switching on/off can be controlled over Ethernet (TCP/IP). Application Note 21 describes how to control relays from the Windows command line sending right sequence
How to get started with HW group devices.
How to reset devices
Factory default reset is used for the following reasons: when a password is forgotten, the IP access filter is blocking access to the device interface or if a customer wants to have the device in factory default after tests or for sale to the customer
How to send an e-mail from the PortStore buffer device
The PortStore buffer device has the facility to send e-mail alert when power failure occurs or the buffer is getting full.
How to use the Box2Box mode
Two devices can be connected back-to-back (Box-2-Box mode). In this mode, the digital I/O as well as the RS232/485 serial line are extended (tunneled) over the LAN.
I/O Controller - connecting relay to 230V AC
I/O Controller can read states of digital inputs and control 8 outputs over network.
Modbus/TCP in I/O Controller2 and IP Relay HWg-ER02b
The I/O Controller device was chosen as an example.
Serial Tx Pause for Eth/RS-232 converter
This application note describes how to pause the remote transmition of data on Ethernet/RS-232/485 converters. This functionality is necessarry if you need to send the output data over RS-232 in precisely defined packets.
