pcb he made with violations of protection , but it's better than the original )

PT VIP 3AC/380 03 Rev. 2 ?
all the boards are different, you need to make a correct connection

The connector to MB is with 5 wires. On S1 appears 6 wires.

you should have the skills to reverse engineering (
or use the help of your friend

martinways Epson EB-W22
neckro Sanyo PLC-XE31

maybe similar, but are different devices

neckro · 2016-09-14 23:47:44

NoName, thank you again for you answer. I followed your advice, and i have started to dig So far, i have found the pins order from http://cncms.com.au/SANYO-SMs/Commercia … e31_sm.pdf (Service Manual) on page 78.
K8H: pin 1 LAMP_SENS , PIN 2 GND, PIN 3 5V, PIN 4 LAMP_SW, PIN 5 ECO. Witch one from those will be TX and RX ?

NoName · 2016-09-15 09:31:33

SERVICE MANUAL PLC-XE31 - its very good )

neckro, projector is working properly?
its important!

ionut · 2016-09-15 15:02:48

Good day,
My code it work, and I don't change nothing in drop box source. But take care on optocuplers interface with mainboard. Here are main big mistakes and this is the reason that code don't work.

Try to copy the original ballast circuit from optocuplers to MCU.
Regards,
Ионуц

neckro · 2016-09-15 22:23:57

NoName, yes, it is! Lamp has few hours left. Ionut, thank you for the scheme! Tomorrow i will build it.

NoName · 2016-09-16 09:29:01

neckro, you need to make transmit data log,

for example

neckro · 2016-09-18 20:01:58

Hello. Until the Saleae will arrive, i have dig more on internet and i have found Standardized UART Protocol and is helping me to understand some things As i see, for me:

Ballast 3AC/380 O3 Rev. 2

case 0x00: Serial.write(0x00); break; //echo
case 0x70: Serial.write(0x70); break; // Enable comnication
case 0xF0: Serial.write(0xF0); Serial.write(0x01); break;// Company ID , default is 01
case 0xF1: Serial.write(0xF1); Serial.write(0x0C); Serial.write(0x07);; break; // F1h + hardware ID + software ID = as table, 0Ch | as software ID i haven`t figure out yet.
case 0xF3: Serial.write(0xF3); Serial.write(0x00); break; // waveform 00 is default as table 3
case 0xF2: Serial.write(0xF3); Serial.write(0x64); break; // ??
case 0xF4: Serial.write(0xF4); Serial.write(0x80); break; // This query returns the single byte value of the actual waveform gain, which has been set with the command
“Set Gain” (for gain calculation formula, see section 2.2.1.7 “Set Gain (72h)”). Can i set gain ???

case 0xF6: Serial.write(0xF6); Serial.write(0x02); break; // This query returns a single byte, representing the total number of waveforms stored in the lamp driver. This can represent projector resolutions?
case 0xFA: Serial.write(0xFA); Serial.write(0x60); break; // This query returns the minimum allowed gain value for the lamp. (for gain calculation formula, see section
2.2.1.7 “Set Gain (72h)”) Again, can i set gain?

case 0xFB: Serial.write(0xFB); Serial.write(0x80); break; // This query returns the maximum allowed gain value for the lamp. (for gain calculation formula, see section
2.2.1.7 “Set Gain (72h)”) ....
case 0xF5: Serial.write(0xF5); Serial.write(0x01); break; // This query returns a single byte, status of the ballast. Table 12 defines the bits of the ballast status
register. Lamp on represent 0.

Even so, is not working yet. Having the pdf above, and using a lcd on arduino, those values can`t be readed from mainboard?

"Even so, is not working yet. Having the pdf above, and using a lcd on arduino, those values can`t be readed from mainboard?"

yes of course, but it's better to send data directly to a pc for analysis.

Hmm... can be used Serial.read and sniffed with Arduino connected to USB?

NoName · 2016-09-20 09:28:08

if Arduino has three ports, yes
1 - in a transparent mode, that received, the sent
2. two inputs line (RX) to the control mode

but, Im use the oscilloscope/logic analyzer

Hi, Saleae has arrived today, but the projectors is broken. I have get all parts together and is not starting anymore even with original ballast. Maybe, i have broke it with arduino?

Update. I got some data but too many frame errors. Is that normal?

25 kHz, 0 M Samples [29]

strange signal, 1/40 mks = 25k
it is not right )

neckro · 2016-09-23 12:09:24

I have made another measurement and got the following data. The measurement is made only on pin 5 on CH0, because if i connect pin 1 to CH1, the projector the lamp turn off after few seconds and projector is keep rebooting.

25 kHz, 0 M Samples [2]

How much i try, pin 1 is causing reboot. Even if is single connected on Saleae.

The projector is not rebooting anymore and got the following data on 50khz:
