There are four issues involved here: 1) Many of those LEDs achieve high mcd ratings by radiating all their energy in a narrower beam than other LEDs. This may make it harder to couple the LED's energy to the optical system (ie: the lens), and alignment becomes more critical. 2) Most Ronja systems are on 24 hours a day. Cheaper LED chips tend to have shorter lifetimes, so you'll need to replace your LED sooner (which is not easy, as it requires dismantling the entire transmitter head). 3) Related to (2): ultimately the amount of power a LED can emit depends on how well it can get rid of its heat. The HPWT-LEDs have a special package with more pins, designed to handle heat better than normal 5mm LEDs. 4) The LED needs to be switched on and off very fast (~40ns max rise/fall time for Ronja, I'd say); not all LEDs can do this. This depends on the materials used in the LED and the size of the LED chip. Unfortunate trade-off: larger LED chips (needed for more power) have larger capacitance and are thus slower to switch on/off. Then again, you can always try, although I would suggest trying to find a LED in a medium-power enclosure like the HPWT.

I see from the datasheet HPWT-MD00-0000 is like HPWT-BD00-0000 but with 100 deg angle instead of 50. That roughly means the lens will cash in only 25% of the power. That means half the range than with HPWT-BD00-0000.

Short Range Underwater Optical Communication Links. The original document is in pdf, so sorry if the block diagrams are missing. UTP ? The UTP (Universal Twisted Pair) is the main interface to the PC. The signal from the RJ-45 port goes into the RJ-45 Filter. The schematic below shows the pin layout of the RJ-45 filter. This filter isolates the board from outside noise. The RJ-45 standard calls for twisted pair wires consisting of a positive and negative wire for the transmit and receive, for a total of 4 wires. This differential output setup is used to reduce any noise the Ethernet cable may receive from outside sources. The positive and negative transmit signal are on pins 9 and 11 of the filter. The respective receiver pins are 14 and 16. This can be seen in the schematic below. The signal is then passed into the transmitter circuit of the UTP. TX Circuit? The transmitter establishes the handshaking between the idle signal and the data stream in preparation to be sent to the LED transmission board. - MC3486 (Quad Differential Line Receiver) ? This IC multiplexes the two differential transmission signals (positive and negative) into one signal. - 74HC74N (Dual D-Type Flip-Flop w/ Set and Reset) ? This IC provides a 1MHz idle signal for the LED. This signal is for maintaining a defined DC level and to prevent receiver noise and unwanted signals from being amplified in the limiter on the receiver board. The system would not work without the 1MHz signal. Packets would be randomly lost due to received packet echoes from the opposite direction on shorter links, sometimes even on longer links due to random noise resembling a preamble, and most importantly, the remaining packet would not be received at all because the corrupted preamble would be received by the RJ-45 interface. - 74HC14N (Hex Inverting Schmitt Trigger) and 74HC132N (Quad Schmitt Trigger NAND Gate) ? These ICs work together to decide if the idle signal or data signal should be passed. If no packet is detected, the idle signal is passed. When a data signal is detected, the idle signal is dropped. The red indicator LED on the board is flashed to indicate transmission activity. RX Circuit - This circuit filters out the 1MHz signal, passes the data signal to a demultiplexer, passes the (positive and negative) signals to the RJ-45 filter which then passes them to their respective receive wires on the RJ-45 port. - 74HC74N (Dual D-Type Flip-Flop w/ Set and Reset) ? Produces Ethernet standard 250Hz (NLP or Normal Link Pulse) signal which tells the PC the UTP is an Ethernet compatible device. Every 4ms this NLP is sent to the PC maintaining the compatibility status. - Common Emitter Pair ? Pre-amplifier for incoming ~700mVpp to ~4Vpp. This increases the current and voltage so that incoming pulse train will trigger the input of the 74HC14N. - 74HC14N (Hex Inverting Schmitt Trigger) and 74HC132N (Quad Schmitt Trigger NAND Gate) ? Rejects the 1MHz idle signal so that it is not passed to the PC. If a data signal is detected it passes the signal, otherwise the 250Hz NLP is sent to the PC for the reasons described above. The green indicator LED on the board flashes to indicate reception activity. - MC3487 (Quad Differential Line Driver) ? This IC de-multiplexes the incoming data signal into separate differential output (positive and negative) receive signals for the RJ- 45 filter and port. Transmitter Figure 5-18 Functional block diagram of the transmitter board, Right) The transmitter circuit. Full circuit diagram in Appendix B. The signal arrives via the coaxial connection. The DC filter removes any DC offset, which leaves a pure square wave. Before the signal is transmitted, the signal must be current amplified to push the LED. This is accomplished by an emitter coupled transistor pair (preamp) and by stacking three 74HC04 ICs. The signal is then ready for transmission via the cyan LED. Receiver Figure 5-19 Functional block diagram of the receiver board, Right) The receiver circuit. Full circuit diagram in Appendix B The receiver detects the photons via the photo detector. The low current signal triggers a dual gate transistor (NTE415) which takes the current from the 12V rail and transmits it to the NE592 video amplifier. The NE592 cleans the incoming rounded signal to a square wave. Pin 7 of the NE592 is part of a differential output which is used to measure the signal strength based on the alignment of the optical signal. This is called the received signal strength indicator (RSSI). Pin 8 of the NE592 is the other part of the differential output and carries the data stream through a pre-amp/limiter circuit consisting of a pair of common emitter connected transistors which limits the signal to ~700mVpp. The signal is then sent to the receiving end of the UTP.

To do this competently you need to be good in electric engineering because there is a lot of related issues which if neglected the device can easily become unreliable. But if you are versed in electric engineering it shouldn't be difficult to see from the schematics how it's supposed to work. > >What I need is, > >1.

Face the one without mechanics against a fibre optic network card set to 10Mbps and it should theoretically work. Not tested practically, though. You also have to match the network card's optical wavelength reasonably and maybe you'll have problems with signal too strong.

I will be very pleased if someone contribute his part of work to it. I have done new pcb layout, for direct driving of led with formerly unused CPLD pins with optional extensive EMI radiation preventing and with direct twisted pair interface to Petr Seligers receiver. Only what stands in the way to fabricate this version of pcb is the fact, that i have not modified the Verilog code and not tested it if it fits into CPLD device as the pinout is designed. The reason is that Xilinx WebPack, the software to design the CPLD inside, stopped working in my gentoo linux after some system library update. Guys at Xilinx do support f*cking RHEL4 and 5 only, besides microshit windows. I will place this new version to website asap.

I have some chips with serial programming disabled, by incorrectly written fuse (device configuration) bits. There is no way to reuse the chips without having a parallel high voltage programer. I do not use PICs but i know some links: http://www.iki.fi/hyvatti/pic/picprog.html http://home.pacbell.net/theposts/picmicro/ http://gputils.sourceforge.net/ http://pikdev.free.fr But if you want to use C language, switch to AVR, they have better harware support (IIRC PIC18xx also do, but there is no PIC target in gcc).
