Hi all,

I want to control my Sony VPL-ES3 projector by using the serial RS232 port. I've searched everywhere for the codes but found only reference to a Sony program "PJSERIALCOMM.EXE", which apparently can be used to generate hex strings to control this and other Sony projectors.

Google turned up a solitary hit to a download link on a Sony site at [Link: sony.ca], but the download starts and then sticks at 0% downloaded, so no luck there!

Can anyone point me at another source for this program or offer any source of the RS232 codes please?

RS

It downloaded ok for me from that site, if you cant get it email me and i will send you.

Hi! Does anyone still have the PJSerial software available to download? AM trying to connect a sony vpl-px20 to a crestron cnmsx-pro via rs-232. I can use the IR serial just fine, but do not have discreet control of input selection. IF PJSerial can show the hex values for the p-on p-off and input-select that's all I would need to control.
I cannot find that program anywhere online.

Thanks!

Crestron and a 15 year old projector. Wow. Is this personal use or for a client?

Doing a little RGB/HV for some 720p resolution from before HD was even really HD. That 4x3 resolution is the big sell for me. :-)

What control do you currently have of the device? If that program is gone, it might be easier to work backwards if we know what work. Sony is not a company to quickly change codes, and there are lots of known codes for Sony devices. So if you post what you have, maybe it can be cross-referenced against some databases.

A potential start

P-On

A9 17 2E 00 00 00 3F 9A

P-Off

A9 17 2F 00 00 00 3F 9A

Video

A9 00 01 00 00 00 01 9A

S-Video

A9 00 01 00 00 01 01 9A

Input A

A9 00 01 00 00 02 03 9A

Input B

A9 00 01 00 00 03 03 9A

Or, if you google "vpl-px20 rs232" literally the second link is this protocol sheet:

Of course, it depends on how strong your serial skills are, as sony protocol sheets usually don't even give an example string.

Lol, yeah, this is for where I work. I wish the stupid proj. would just die, Then at least they would be forced to replace it, and the screen.
I am "upgrading" a CNMS with a CMNSX-Pro (ha ha), and don't need an 8 channel switcher for two signal sources (small system), so I just want to have discreet input selection on the pj.
I did find the protocol manual, and like you said, there are no examples to work from, and I have forgotten just about anything I knew about rs232. I think what you have posted will help out tremendously.
It's funny, the original CNMS program was written in Crestnet Workshop, a DOS program! Was a real gas getting it to run in 64bit Windows 8. Wound up starting from scratch on the CNMSX-Pro.

Those protocol sheets are designed for engineers. They are brutal, even if you know what you are looking for. It's an awful document, no matter how much you know about serial commands.

That being said, I have a surprise for you.

On post 5, someone lists the commands for discrete power. That's a great base to go off of.

Post 10 someone actually uploads the pjserialcomm file, but because of its "large" upload size of 700kb, they split it into two archives the wrong way. After spending about two hours trying to get the files to extract and downloading old versions of winzip, I finally gave up. Fortunately, google is our friend.

I tried to upload it to the file section of this website, but google is not my friend and won't let me send a compressed zip file as an attachment for "security reasons." Hopefully aalbert (at) biggerhammer.net will keep his website active for years to come. Meanwhile, I have the exec file saved on my dropbox or you can pull it from the link above.

However, if you prefer, you can tell me what codes I have posted work for you and don't work for you, and we can continue to go through my (substantial) db. We'll find something.

Wow, I sure do appreciate all of the effort you are putting in to help me out.

I was able to download the PJSerial from the biggerhammer link. With it I was able to control discreet input selection, but none of the PJs listed would work for power on - off.
Then my luck changed, and a good thing too, I was about ready to hang myself with the serial cable when I just sort of stumbled on the solution.

After taking a deep breath and counting to ten, I started playing with different one-way IR serial drivers, thinking that I could use rs232 for input selection, and the IR serial/control S for power control. After trying out all of the drivers for Sony PJs in the database (16.4.0) I stumbled onto the VPL-X2000U IR driver.
I was thrilled that now I could control power, and then I noticed there were discrete inputs as well, and they worked too! So for now I have had my fill of rs232 with PJs.
The Sony protocol manual does make a terrific disposable fly swatter.

Thanks for all of your help!
