I/O Controller 2
Ethernet –RS-232/485 + inputs and outputs
I/O Controller 2 is an Ethernet-enabled device with 8 digital inputs,
8 digital outputs and a RS-232/485 serial interface.
All interfaces are accessible over TCP/IP using a M2M
protocol.
Two devices can be connected against each other
(Box-2-Box mode) in order to extend the digital and
RS232 signals over the computer network.
Basic features
•1x full RS-232 or RS-485 serial port accessible over the Ethernet.
•The remote port can be controlled with a virtual driver for Windows just like, for example,
COM 5 (a Windows XP / Vista / Windows 7 / Server 2003 / Server 2008 / x64 driver is
available free of charge). Compatible with RFC2217.
•100 Mbps Ethernet interface –100BASE-Tx, RJ 45
•Support for TCP/IP terminal, TELNET –NVT type (Network Virtual Terminal)
•Two devices can „tunnel“ the serial port, 8 inputs and 8 outputs over the Ethernet
•Web-based interface for configuration
•Wide range of supported serial interface parameters:
•Communication speed configurable from 300...115200 Bd
•Handshake (CTS/RTS, Xon/Xoff, none)
•Full serial port (Cannon DB9M - RxD, TxD, CTS, RTS, DSR, DTR, RI, CD, GND)
•Support for 7th to 9th parity bit (9th parity bit transferred over the Ethernet)
•SDK (Software Development Kit) is available for the device with examples for MS Visual
Basic, Delphi, Borland C++, JAVA, PHP and more

Digital Inputs & Outputs wiring
•GND –device ground.
•PWR –device power (max. 200 mA).
The device can be powered from barrel power connector (front panel) or from the I/O
connector PWR + GND pins (200 mA internal fuse = suitable only for testing purposes).
•I.GND –common ground for optocouplers.
•I.0 to I.7 - 8 optocoupled inputs 5-20V
All 8 inputs are realized using common ground optocouplers (I.GND pin). The pins can then
be controlled using the contacts together with the POWER pin, which has the power adaptor
voltage (connect I.GND with GND).
Warning: The digital input voltage range is 5 -20V, but be careful for max total current thought
I.GND pin which is 200mA for all digital inputs (cca 25 mA per singe Digital Input).
•O.COM (Common) –Overvoltage output connected to the plus pole of the power source. This
can be useful when you want to control a relay from this output.
•O.0 to O.7 - 8 open collector outputs, with common diode overvoltage protection.
The outputs a realized using 8 open collector transistors. Two outputs are internally connected
to a relay, which contacts are also led out to the device’s connector. The protecting diodes are
connected to the “common” pin, which should be connected to the plus pole of the next device
(for example a relay). This way the pins can be protected against load peaks.

Quick SETUP
Connecting the cables
•Connect the supplied power
adapter to an electrical outlet.
•Set DIP1 and DIP2 to OFF.
•Connect the device to the
Ethernet.
•Connect the power adapter to
the power connector at the
device.
•If the power is OK, the green
Power LED lights up.
•If the Ethernet connection works
properly, the LINK LED lights
up, and then flashes whenever
data transfer takes place
(activity indication).
Configuring the IP address
•Start the “HerculesSetup.exe” utility. It is available on the DVD (included in the “set” package)
or for free download at www.HW-group.com.
•In the “UDP Setup” tab, click “Find modules”. The MAC address of the device appears in the
left column. Click the MAC address and set the required parameters (at least the IP address,
mask and gateway).
•Make sure that “Enable TCP Setup” is checked. Click “Set module” to save the parameters to
the device.
•You have now configured the IP address and other networking parameters and you can work
with the device.
MAC address not visible in the list?
LINK LED did not light up or the device does not respond? Please double check the following.
- Does your Ethernet network support 10 Mbps devices?
- Are you using a correct TP cable (straight-wired TP Patch when connecting to an Ethernet
switch, crossover cable when connecting to a PC)?
- Check the DIP switch settings (all should be OFF).
- Check your power adapter, make sure the Power LED is on.
- Check the firewall settings at your PC.
