Introduction
The IRTrans with Ethernet interface offers the same basic functionality as the "normal"
IRTrans modules. Using the Ethernet interface and integrated TCP/IP stack the module can
be integrated in any Ethernet network. The IP interface is realized using the Freescale
MC9S12NE64 Microcontroller with 64K flash and 25MHz clock.
The TCP/IP stack has got the following functions:
•
Web server to configure system parameters
•
DHCP client for the configuration of the IP Address
•
Sending and Receiving IR Commands via UDP
•
Firmware updates for the Ethernet & IR controller via UDP
The complete UDP communication is done via the officially registered UDP port 21000. If
needed this port should be opened in firewalls.
Devices with integrated IR Database have got these additional functions:
•
Sending and Receiving of IR Commands using the IRTrans Client/Server
interface. That means the system can be used without an IRTrans server.
•
Sending and Receiving of IR Commands using ASCII UDP commands
•
Download of the IR Database via UDP
•
NTP based real time clock with 4 independent timers
•
128 KByte Flash Memory for HTML pages
(only PoE Devices or LAN Devices with a version >= 2.2)
The IR Database has got a capacity of 128 KByte, which is enough for around 1000 - 1500
IR Codes (64 KByte for IRTrans LAN Modules with hardware version 1.2). Devices with
hardware version 2.2 and PoE Devices with IRDB additionally have 128KByte Flash
Memory for HTML pages.
The Ethernet interface is configured for 10MBit. The hardware also supports 100MBit;
however there will be no advantage as the packets are only 50-200 bytes in size. Using
100MBit the device draws a lot more current which will heat up the very small case
considerably.
The IRTrans Ethernet needs a power supply with 7.5-16V DC / 300mA. As the internal
voltage is generated using a switching regulator which voltage is used to power the
devices. A good selection would be to use 12V DC.
Devices with a hardware version 1.2 have an operating voltage range of 7,5-12V DC / 300mA. The
voltage should be selected as low as possible to keep the heat dissipation as low as possible.
Therefore the power supply we sell should be used with its 7.5V setting.
The IRTrans devices use a standard DC Plug with a diameter of 5.0mm outside / 2.1mm
inside. The positive pole has to be on the inner connector of the plug.
Important: When a power supply with exchangeable plugs / adaptors is used care
should be taken to use the correct plug. A plug with 5.5/2.5mm might also fit into the
socket but it will not have sufficient contact on the inner pole.
