Author Topic: Dolby DSS200 & AP20 Serial Cues... Mike Pearson Film Handler Posts: 2 From: Seattle, WA, USA Registered: Jul 2013 posted 08-05-2014 10:34 PM                    Hello all, I've got an auditorium equipped with a Dolby DSS200 and an AP20 processor, and I can't seem to figure out how to successfully create serial cues in the SMS to select sound formats, adjust volume, etc. in the AP20. Can anyone who's setup a Dolby with an AP20 help walk me through this? Both seem to have compatible serial options, but the manuals are very unspecific when it comes to the process. Thanks for any help.  |  IP: Logged Harold Hallikainen Jedi Master Film Handler Posts: 906 From: Denver, CO, USA Registered: Aug 2009 posted 08-05-2014 11:00 PM                        This MIGHT help. It's from the USL JSD-60 manual regarding entry of control codes. In Show Manager, on the "serial automation" system page, there is a "termination" field where you can put byte codes to be added to the end of each command. By default the system includes "\0A" (line feed) in this field, but you can change it "\0D" (carriage return) or any other sequence. This will terminate each automation string. To insert a tab in an automation string, use “\09” .

I hadn't thought to check Dolby serial automation setup with other non-Dolby processors. I'll give it a go.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 08-06-2014 03:25 AM                     Mike, depends a bit on how much experience you have with serial communication. Basically, the Dolby has no predefined commands for the AP20. You have to read the AP20 serial/network communication doc and create the necessary commands on the Dolby yourself. It's probably to complicated to go through this in detail on the forum, but in general: - tell the DSS200 to use serial automation for this auditorium in ->System->Auditorium - Go to the serial automation tab, set communication parameters to 9600, 8 data bits, No parity, 1 stop bit, no flow control - Set the same parameters on the AP20 in ->System->Automation->Serial, also set Serial command mode to AP20 You then have two choices - either you send to the AP20 those messages defined in the TN-H413 document, or, you can create your own simplified protocol from the Dolby. The AP20 allows you to capture any serial command on the serial interface and use it as an incoming automation event. That is, you could define a serial output on the DSS200 'AP20fader=5', make the AP20 detect and act on it, etc. The capture function in the AP20 automation event setup is very helpful in getting this going. I would suggest to test initial communication and termination characters between Dolby and AS20 that way, then once you feel safe, create the defined AP20 protocol messages and stay within that scheme. The AP20 will support both at the same time. You need to use the leading @ and trailing <CR> scheme (should be \0D as Harold writes above) for AP20 protocol. - Carsten  |  IP: Logged
