Greetings all. I'm not using Crestron for this site but wanted to see if anyone can see if this is the correct string to send.. I used a SUM calc online because im not that far in my travels to understand fully.

What im trying to send: Call Preset
byte 1: 0xFF
byte 2: Address
byte 3:0x00
byte 4: 0x07
byte 5: 0x00
byte 6: Preset ID
byte 7: SUM

What I am sending for preset 1 for example (not working): Cam is at ID1 address 1 and presets range from 1-4
byte 1: FF
byte 2: 01
byte 3: 00
byte 4: 07
byte 5: 00
byte 6: 01
byte 7: F7

Between each byte in RTI im sending a % sign so.. %FF%01%00%07%00%01%F7
We used to have a guy that could help me but hes no longer with us and with the Visca protocol We were able to use the % sign like above to get pan/tilt/zoom working.?
What am I doing wrong?

I believe the checksum byte should be the sum of the bytes (without the leading FF) then modulo, so it should be:

byte 1: FF
byte 2: 01
byte 3: 00
byte 4: 07
byte 5: 00
byte 6: 01
byte 7: 09

?

*modulo 256

Any particular reason for using the Pelco protocol?

These are just rebranded Minrray cameras. They use standard VISCA commands. No matter what platform you are using for control, just find a Vaddio Roboshot module and it should work perfectly. The only thing you may have to work around the module for (if it’s AMX) is presets.

Thanks, I'll have to do some more digging. I did find a Spectra IV camera module that uses the Pelco-D protocol that when my guys were on site I would test the commands already in the module. I was only looking for Pelco-D because I missed the Visca call preset command. I believe the call command is the "memory recall" command. I can also try that.

Is there anything anyone would recommend getting better at strings, and such?
