Just experimenting with Command fusion, and have Onkyo and Oppo working fine with RS232. But I cant work out how to use the sony protocall. [Link: esupport.sony.com]If anyone can help or have a list of the nessesary codes it would be great

I didn't see the protocol on that link, but I have to admit I didn't really look that long. If it is like every other Sony projector I have controlled via serial it will require a null modem. The settings are 38400, 8, 1, and even. I have never messed with Command fusion but try this for your Power On command A9 17 2E 00 00 00 3F 9A. If you have no luck try using a terminal program from your laptop such as hyper terminal.

Both posts are bad links. I'll use the VW85 protocol.
38400, 8-Even-1
All commands are 8 bytes long.
Byte 0 - Start Code - Always "A9" Byte 1 - Item Number Upper Byte - From Item List - Table 1 Byte 2 - Item Number Lower Byte - From Item List - Table 1 Byte 3 - Type - Always "00" for setting a value or "01" for querying Byte 4 - Data Upper Byte - From Item List - Table 2, left 2 digits Byte 5 - Data Lower Byte - From Item List - Table 2, right 2 digits Byte 6 - Checksum - Byte 1 to Byte 5 using the "Or" function Byte 7 - End Code - Always "9A"
Let's try setting the Wide Mode to Zoom. Item Number Upper Byte= 00 Item Number Lower Byte= 20 Data Upper Byte= 00 Data Lower Byte= 03
So: Byte 0=A9 -Start Code Byte 1=00 -Wide Mode Upper Byte Byte 2=20 -Wide Mode Lower Byte Byte 3=00 -Set Byte 4=00 -Zoom Upper Byte Byte 5=03 -Zoom Lower Byte Byte 6=23 -Checksum (See below) Byte 7=9A -End Code
The Checksum is calculated by using the "Or" function. The best way to do this is by using Windows Calculator. You must put the calculator into scientific or programmer mode to show the "Or" function. You must also change from DEC to HEX. The checksum is the result of the Or function from Byte 1 through Byte 5. The "Or" function works just like + or -.
00 or 20 or 00 or 00 or 03 = 23

I am having the same issue...
I used marks post (the only thing I wasn't sure how to do was calculate the check sum, THANKS!!) to figure out the commands, but nothing is working
I am using an RTI ZRP-6 on RS232 port 1. Baud is 38400, parity is even, Data bits 8, stop bits 1.
I have tried various delays between characters 0 to 6 miliseconds to no avail.
Any advice?????
Thanks James

Figured it out... RTI and sony transmit on different pins. Needed a null modem cable between them...
So Thus Mark's info was good!
Thanks!!
