Application Notes
Application Notes helping you to understand how to use HW group products in you applications. Application Notes are intended for use by presenters, educators, administrators, and anyone else wanting more detailed information about a particular topic. As more Application Notes are developed, they will be added to this page.
- AN29: PosDamIO - use command line to control outputs
Poseidon Damocles I/O is a line utility for Windows and UNIX. It enables to control Poseidon and Damocles units over XML interface, show list of sensor's states, inputs, outputs as well as to setup output to log. 1 or 0
- AN28: Damocles family & Modbus/TCP
Application examples show how to use the Modbus/TCP network protocol for communication with Damocles family products (models MINI and 2404). Use „Modbus Poll version 3.2“ program to test communication – Windows PC client over Modbus/TCP that is for free in limited version.
- AN27: I/O Controller - connecting relay to 230V AC
I/O Controller can read states of digital inputs and control 8 outputs over network. Inputs and outputs are designed for low voltage up to 50V. This application note describes how to connect relay to I/O Controller. You can control 230V AC (110) device over external relay or detect voltage over switching contact of 230V AC relay.
- AN26: PortBox and Epson lx-300+
Epson LX300 is a typical dot matrix printer with single sheet/fanfold paper feeder. It can be connected to LPT or RS-232. This article describes how to connect this printer to a serial port and make it accessible via ethernet network using the RS-232 - Ethernet converter PortBox.
- AN25: Replace a serial printer with the PortStore - network serial buffer
A serial printer is still nowadays used to monitor reports from various devices like is a central alarm unit or fire alarm. Sometime it can be useful to monitor printed data over Ethernet network or simply replace the serial printer with any unit and collect data over the network..
- AN24: Using SP Duo dongle
with Charon 2 DK
Application example AN24 connecting SP Duo programming dongle to the Charon2 development kit module. How to connect SP Duo to the DK board over SPI as well as JTAG interface and use in the AVR studio.
- AN23: Serial Tx Pause for Eth/RS-232 converter
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. This way you can ensure the precise timing on the serial port output.
- AN22 - How to send an e-mail from the PortStore buffer device
The PortStore buffer device has a feature to send an e-mail alert when power failure occurs or the buffer is getting full. These functions are great when you use PortStore as CDR/SMDR buffer for PBX in remote location. For using of this function is necessary to have installed a SMTP server on network which takes care of delivery of e-mails. This application note describes configuration of the PortStore with a freeware SMTP server for MS Windows - Free SMTP server
- AN21: Controlling of IP Relay using program NetCat
The IP Relay device contains except RS-232 serial port also another two relays, which switching on/off can be controlled over Ethernet (TCP/IP). Application Note 21 describe how to control relays from the Windows command line sending right sequence using program NetCat.
- AN20: UDP Config in your application
Most of the HW group devices allow you to set the IP address using UDP broadcast. It's implemented in the Hercules utility for example. The AN20 is for companies, who want to implement the device search in their applications
