IP serial products
PortStore4
PortStore4 enables data collection over RS-232 and LAN (custom IP protocols). The PortStore4 uses various methods to read printed data and stores them in the internal flash. The device works with the PS Eye application for collecting data to text files.
In a typical application, PortStore4 collects printed CDR data from PBXs (CDR/SMDR). Data can be retrieved even from VoIP IP PBXs.
Up to 100 printer outputs can be redirected to the HWg-PS Eye application and the data stored to 100 text files.

PortBox
PortBox is RS-232/485 serial to Ethernet IP converter, also known as a “terminal server” or a “device server”. HW VSP for Windows is included for free.
The PortBox converts a RS-232 or RS-485 serial port to Ethernet (IP) over TCP or UDP.
In a typical application, PortBox is used to connect a remote RS-232 device to a virtual serial port (e.g. COM17) on a PC. One PC can be connected to a maximum of 64 remote serial ports.

PortStore2 PL
Data collection from a serial RS232/485 port to the internal flash (2Mb), safe transfer over LAN. Together with the PS Eye application, captures serial printer data and stores the data over IP to text files. The PortStore2 PL connects to a printer output (RS-232) and transfers printed data over LAN. It can work together with the printer.
In a typical application, PortStore2 PL captures serial printer data instead of (or together with) the printer. Up to 100 serial ports can be redirected to the HWg-PS Eye application over LAN and the data stored to 100 text files.

I/O Controller: HWg-ER88a
Ethernet terminal server (RS-232/485) with I/O. Supports Telnet and a remote serial port in Windows (HW VSP). Industrial model, fits on a DIN rail. I/O Controller ER88a is an industrial converter that connects a serial port (RS-232/485), 8 DI (dry contact inputs) and 8 DO (Digital Outputs) to an Ethernet network.
A typical application is connecting a switch over a LAN to a remote relay output. A button in Prague can control a light in Amsterdam (DI Ethernet DO).

I/O Controller: HWg-ER84a
I/O Controller ER84a is an industrial converter that connects a serial port (RS-232/485), 8 dry contact inputs and 4 relay outputs to a LAN (Telnet protocol). Free Windows virtual serial port included. Industrial model, fits on a DIN rail. It is controlled over TCP/IP using a Telnet-like M2M protocol.
A typical application is connecting a RS-232 serial printer to IP, accessing remote dry contact inputs (door contacts, buttons) over IP or controlling a remote relay output for resetting a printer or activating alarm.

IP Relay HWg-ER02a
IP Relay HWg-ER02a consists in two 230V relays and a RS-232/485 serial port controlled over the Ethernet (Telnet).
Two relay outputs capable of switching 230V, and a remote serial port over IP. Industrial version, mountable on a DIN rail.
In a typical application, IP Relay is used to open a gate remotely over a LAN (230V relay output) and to connect a RFID card reader (RS-232).

I/O Controller 1204
LAN to RS-232/485 serial port converter with 12 digital inputs and 4 outputs. Accessible as a remote serial port in Windows, or via Telnet. The serial port is accessible via a Telnet protocol. Alternatively, it can be redirected to a virtual serial port in Windows (e.g. COM 27).
In a typical application, I/O Controller is used to connect external inputs (door contacts) and a RS232 device (banknote counter) to a central server.

I/O Controller PL
Ethernet to RS-232/485 serial port converter with 8/8 digital inputs/outputs. Accessible as a remote serial port in Windows, or via Telnet.
Typical applications include extending a serial port and I/O lines over an IP network by connecting two I/O Controllers against each other (“tunnel“ or prolong the I/O & serial).
The I/O controller is frequently used for connecting peripheral devices to a central server. A barcode reader is connected to RS232, buttons are connect to digital inputs, and status indicators (a light tower) are controlled with digital outputs).
