Dolby DR-37P Standard Operating Procedures

This document describes Standard Operating Procedures (SOPs) that should be followed for the Brightside/Dolby DR-37P HDR display located at the time of this writing in ICICS X521.

If you have any questions about this display, please contact the following people in this order:

• Allan Rempel: ICICS X709, agr@csDELETEthisTEXT.ubc.ca, 778-999-3526
• Matt Trentacoste: ICICS X709, mmt@csDELETEthisTEXT.ubc.ca
• Wolfgang Heidrich: ICICS X639, heidrich@csDELETEthisTEXT.ubc.ca

Power up procedure

• 1. Power on the HDR display.
• 2. Connect the USB cable to the HDR display.
• 3. Log in to the computer.
• 4. Run DR-37P GUI V48.5.exe.
• 5. Click on 8-Bit+ Mode.

The default mode for the display upon power-on is a high-brightness mode, which can cause significant heat. For most uses, check the 8-Bit+ Mode box in the HDR Control Panel. This enters a lower-brightness mode which substantially reduces the risk of overheating. This mode is also suitable for high-brightness use of the display, because HDR Viewer expects this mode for displaying full-brightness imagery.

Magnetic liquid cooling pump

• Check the "Manual Override" box on the HDR Control Panel.
• Double-click on the "Pump %" box and set it to 0.
• Double-click on it again and set it to 50.

This should restart the pump, and you should fairly quickly observe a decrease in temperatures. You will also likely hear an additional spinning sound as the pump spools up.

Power down procedure

• 1. Terminate all programs on the computer, including HDR Control Panel
• 2. Log out of the computer.
• 3. Power down the HDR display.
• 4. Unplug the USB cable from the HDR Display.

Remote development with Dolby

The display has shown a risk of overheating that could lead to automatic shutdown. These SOPs are designed to mitigate that risk.

Ensure that there is enough FC-11 (FC-77?) liquid coolant in the reservoir of the display. Allan thinks enough means more than half full, but that's just a guess.

When powering on the display, do not wait long before logging in and running "DR-37P GUI V48.5.exe". This control program allows you to monitor the temperatures in the display as well as control it. When you run it it should ask if you want to connect to display 1106 and you click OK. If it can't find the display, you will need to log out and back in.

Use the following steps to log in: 1. Power on the HDR display. 2. Connect the USB cable to the HDR display. 3. Log in to the computer. 4. Run DR-37P GUI V48.5.exe. 5. Click on 8-Bit+ Mode.

The default mode for the display upon power-on is a high-brightness mode, which can cause significant heat. For most uses, check the "8-Bit+ Mode" box in the HDR Control Panel. This enters a lower-brightness mode which substantially reduces the risk of overheating. This mode is also suitable for high-brightness use of the display, because HDR Viewer expects this mode for displaying full-brightness imagery.

When cold, the temperatures should be in the mid-20s. Even in 8-bit+ mode, the temperature may climb into the 30s when not using HDR Viewer, or higher when using HDR Viewer. This is a sign that the cooling pump might be stalled.

If you suspect that the cooling pump might be stalled, it can be restarted with the following procedure. Check the "Manual Override" box on the HDR Control Panel. Double-click on the "Pump %" box and set it to 0. Double-click on it again and set it to 50. This should restart the pump, and you should fairly quickly observe a decrease in temperatures. You will also likely hear an additional spinning sound as the pump spools up.

The pump is magnetically actuated but sometimes the magnetic field breaks down, or the pump doesn't even start when the display is powered on. Setting the pump to 0 and back to 50 restarts the magnetic field and gets the pump going again.

When the temperatures hit the 60s or 70s, exercise caution and keep an eye on them. When they hit the 80s, you should take steps to reduce the temperatures by either restarting or increasing the speed of the pump, setting the 8-bit+ mode, ensuring there is coolant in the reservoir, or terminating the display of bright images. If 8-bit+ mode is on and the pump is running, then terminating the display of bright images should cause a dramatic decrease in temperature. The last option of course is to power down the display.

If you power down the display, do not simply power it back up and leave it. You will need to exit and restart the HDR Control Panel ("DR-37P GUI V48.5.exe") so that you can monitor and control the temperatures. You will also need to plug out and back in the USB cable connecting it to the computer, to reestablish that connection.

Use the following steps to log out: 1. Terminate all programs on the computer, including HDR Control Panel 2. Log out of the computer. 3. Power down the HDR display. 4. Unplug the USB cable from the HDR Display.

Users of the display who also have active accounts at Dolby can access the Dolby SVN server (elmo.dolby.net) and do code development with the following process.

elmo.dolby.net is only visible when a VPN session with Dolby is started. To start it, set your browser to vpn.dolby.net and log in with your dolby username and password. Click "Allow" to (do what the popup window says...). Now you can find elmo.dolby.net. It is not necessary to click the Start button for Network Connect in the Client Application Sessions section of the Instant Virtual Extranet page that comes up, and in fact if you do click it you will lose internet connectivity to anywhere outside of Dolby (e.g. you will lose all UBC access).

When you are finished, click the Sign Out button on the top right of the Instant Virtual Extranet page to log out of the Dolby VPN. Also, the Dolby VPN will time out after a while (at least several hours, but less than 24 hours).

When the Dolby VPN is running, you can access the SVN repository by creating your local directory (e.g. thirdparty, code, brightview) and right-clicking on it to SVN Checkout... From there you can specify the URL of the repository as follows:

svn+ssh://username@elmo.dolby.net/srv/svn/repository

where username is your username on elmo (which might be different than your Dolby username) and repository is the name of the repository you want (e.g. thirdparty, code, brightview). E.g. regarding usernames, my elmo username is "allan" while my Dolby username is "aremp". This might only apply to employees with elmo accounts before Dolby bought Brightside, if all new employees are automatically given accounts on elmo that match their Dolby usernames.
