Hello,
I know a few years ago there was someone looking for an Infocus pinout to do the firmware upgrade. It's silly that Infocus made all of these proprietary connectors...
The Cablewizard connector looks to be a HDR40 (or similar type) connector. To upgrade the firmware either an HDR40 (or similar type) to DB9 RS232 adaptor is required. Then simply a null modem cable to a laptop or computer's serial connector will do the job.
The other method is using a Cablewizard or Cablewizard2 to connect to the HDR40 connector which has a "PC serial" connector. Unfortunately, this "PC serial" connector is a 5 Pin Mini Din non-standard connector. So a proprietary Infocus 5 Pin Mini Din to DB9 cable is required.
Does anyone know what the pinouts are?
I'm going to purchase a male 5 pin Mini Din connector and try to discover the pinouts with a multi-meter... any tips? Thanks in advance.

After a bit of testing and playing around with my custom adaptor, I'm still trying to get it to work...
The one confirmed pin is the ground pin. When the PJ is on, 2 of the remaining 4 pins show -8.8v and the last 2 show 0v.
The laptop DB9 connector pins show -5.4v on the TxD pin and 6.6v on the DTR and the RTS pins when I initiate a detect via the Infocus Firmware upgrade software.
Leads me to believe that some form of flow control is used. The Infocus instructions tell you to select "none" for flow control but the signals indicate otherwise unless they are not actually used for flow control and just some proprietary signalling for the Infocus.
I tried many combinations without luck. I should have been more scientific and listed all the possible combinations and tried them one by one...

Hi ,
I can't help with the adapter but here's a bit of background . DTR means the interface is enabled or the terminal equipment is powered on . The other end should reply with DSR or maybe hold the DSR signal permanently high to indicate it's also powered on . Flow control is performed with RTS and CTS . RTS = ready to send , this is sent from the DTE (terminal) , the DCE (modem etc) will reply with CTS = clear to send . Most equipment these days just uses a 3 wire interface : RX/TX and 0V . You will may need to establish if both devices are DTE , if so , implement a crossover cable : TX-RX , RX-TX . Hope this helps , I'm just quoting off the top of my head here 🙂 Maybe do some Googling 😉
cheers

Thanks man. I'm definitely armed with lots of info from Google.
The challenge is that I'm being thrown off by the Infocus software sending signals through the flow control pins DTR and RTS. The Infocus cable having 2 -8.8v signals is also throwing me off as it also suggests that one is for flow control...
I'll have to play with it some more. I am getting terminal response with certain pin combinations that allow me keyboard input but it unfortunately feeds back "@" characters continuously. That's the best I've gotten.

Hi ,
No , flow control is via RTS/CTS . Don't worry about those signals , you can force then high on the other end of the cable using signals from the other device if need be . DTR means the interface is enabled or the equipment is powered on . Those '@' characters you are getting is probably as a result of a speed mismatch between equipment . Try resetting the speed eg try 1200bps , then 2400bps , 4800bps etc until you get the correct response

lp350 frs232 pinout
I've opened LP350 to see what are the pins on minicentronix36 that are connectred to the signal lines. It uses more than 2 signals! (not just rx/tx)
Threre is ground pin, single ended pin and 3 current loop pins. I do not have centronics connector, but once I get one - I will make a patch panel and see how it should be connected.
Who knows what was specifically done with the power supply in an upgrade?
One other suggestion - big cooling fan in infocuslp350 gets max of 7.2v voltage through regulator. If you will not be able to upload software 2.1 - you may want to drive it from +12v - it will improve [obviously insufficient] cooling in 350

Thanksf for the post vpredtec!
I suspected it must use more that just the TXD, RXD and ground... I assume that you must also have the cablewizard cable to figure out it needs more than the TXD and RXD...
LMK if I can provide you more info on the signalling... from what you've indicated, it sounds like we need GND plus 3 wires. I assume that 2 are TXD and RXD and one more unknown. If you know which 3 pins these are, I can try some plug and play with the laptop tonight and report back...
I haven't been able to find out what was specifically changed with the power supply. Infocus and the service centers are tight lipped about it since they want to charge money for the work...
I hear that it has something to do with too much voltage going to the bulb which contributes to it running too hot. I think your suggestion on the fan is also a good one. Maybe I need to find a way to move more air through this unit...

I've already closed mine, but it is ground + 1SE + 3current loops - total 5 wires. Single ended is pin1, ground is like pin7 or5 or 9, i do not remember exactly, and current loops are pin pairs in range 17-18 19-20 21-22 or nearby, they are paired closely to each other. If you connect it to PC com port, you need to ground one end and drive (or sense) another.
I also suspect that because they use mini centronics it might be as simple as parallel printer cable that goes into DB9-DB25 null-modem cable that goes into com port. But I'm not sure, need to check pinout.
I've removed their power supply, it is pretty basic, does not have true power regulation (requires both current and voltage to be monitored), so I plan to replace ballast and use standard UHP lamp of a lower wattage and lower cost. switching the fan to higher RPM sounds like a must to me too, because they have no temperature sensors to judge on lamp regime.
Good luck with your experiments, software upgrade becomes second priority for me with power supply being the first.

Keep us updated on the power supply and bulb.
The cablewizard connector is a multi-function adaptor that allows input for mouse, VGA in, Monitor out, Applebus, Serial and Audio.
With the cablewizard, at least all I have to worry about are the 5 pins and I know that one is ground so it's really just 4 pins. The challenge is knowing which of the serial signals it's using...
So if I know the ground then only 8 pins are in question for the DB9 and 4 pins for the 5 Pin Mini Din. That's a raw permutation of 1680. I know which pins have voltage changes but I can't confirm 100% which DB9 pins are NOT used... since it's proprietary, I may need to tap into all the DB9 pins to see if there is a reaction when signal is given to certain pins...

Closing the loop... (no pun intended)
I recieved a repsonse from Infocus after I sent a letter about my issue. They provided me with a schematic / design doc of the 210-0107-00 cable that goes from the Cablewizard to a DB9 connector.
After looking at the wiring diagram, even if I went through 1680 permutation and hit the correct pinout, it would not have worked as there is a loop at the DB9 connector which I would have no way of knowing unless I saw this diagram for reference...

I updated the firmware to 2.1 last night. The Windows program didn't work in XP so I resorted to creating a Boot CDROM with the Infocus 2.1 software on it.
I ran the DOS batch file and it updated the no problems.
I immediately noticed that the internal fans ran faster and confirmed from Infocus that the fan algorithm is what the 2.1 firmware updates.
I'm also going to see if I can increase airflow externally as well to help.

Hello Lithiumus,
I've have the exact same projector as you. I'm very happy with it but I too would like to upgrade the firmware. Would you accept to mail me or post the cable schematic?
Thanks beforehand.

Hello, I don't have a problem with you contacting me. Configure your profile on this forum to allow e-mail and I'll send you one.
I actually have the Cable Wizard 2 with my custom created adaptor with a boot CDROM with the new firmware all ready to go and packaged for shipment.
I was going to sell it on eBay but if you are interested, I can sell it to you. LMK when you've enabled your E-mailing. I have also done the same so you can E-mail me through the Forum. Talk to you soon.

Hello lithiumus,
As I'm a junior member of this forum I still can not use the "send email" option. So here is my email: ax_el@mac.com
Could you please contact me so we can talk about the adapter?
Bye for now.

Hello lithiumus,
I want to update the firmware on my LP350 projector as well. Would you share the doc you received from infocus to me? My e-mail address is ihaiders@gmail.com.

Hello lithiumus,
I just found this forum and joined up, so I can't send emails to members directly yet. I also have the LP350 that I would like to update the firmware on. Could you email me at ifversen@sbcglobal.net about this adapter schematic? Thanks!
