Q I'm used to the DVM-7400. Where is the 'Test Button' on the DVM-8400? 
A Since the DVM-8400 has an LCD menu interface, it does not have the traditional test button that is found on most of our other products. However, you can easily access the test feature by pressing the knob 3 times. This selects the menu option 'Main Menu-->Play Menu-->Play Test File'. This will cause the lowest numbered clip on the flash card to start playing.
Q I see that the inputs of the DVM-8400 can be Contact Closure or Voltage inputs. How do I configure this? 
A This is done on the front-panel of the DVM-8400. Just go to IO Setup-->Input Type. As a side note, there is no need to worry about connecting voltage inputs when the product is configured for contact closure operation. This will not cause damage (as long as this voltage is 24VDC or less). The only effect of having the incorrect input mode configured is that the input may not work reliably.
Q What do the inputs of the DVM-8400 do exactly? 
A It depends. The inputs of the DVM-8400 can actually operate in one of several different modes. The default mode allows you to play files 1-8 with inputs 1-8. For the other modes, see the DVM-8400 manual.
Q The DVM-8400 has 4 different types of video outputs. Are they always on?
A Yes. The analog component, HDMI, and HD-SDI outputs will always display the currently configured Video Output Format (which is 1080i by default). The composite video output will always display a Standard-Definition mixdown of the HD output. No configuration necessary. 
Q Do the HDMI outputs and HD-SDI connectors output audio?
A Yes. The HDMI connector will output S/PDIF audio or a surround sound bitstream (i.e. Dolby Digital) depending on what type of audio is encoded in the video file. The HD-SDI will only embed audio when playing 2-channel audio formats.
Q What types of video files does this product play? 
A It will play video elementary streams that are encoded with MPEG2, H.264, or VC-1. It will also play Transport Streams that contain 1 of those 3 video types, as well as an MPEG, AAC, or AC3 audio track. It WILL NOT play Program Streams, Quicktime MOV, WMV, MP4, M4V or AVC multiplexed files. See the Media Files section of the manual for detailed information. 
Q Will this product play Standard Definition video files? 
A Yes. However, it will not play Program Streams. The SD video must be encoded as an elementary stream or a transport stream.
Q What's the best way to control this product from an AMX, Crestron, or other 3rd party control system? 
A Using the Pioneer/AMI protocol via the RS-232 control port, or via Ethernet on UDP port 2638. If you are using RS-232, you must have a straigh-through (not NULL) serial cable and you must use the settings 9600-8-N-1. See the DVM-8400 manual for detailed instructions and a complete list of commands. 
Q In the DVM-7400 and the AM-4 you usually had to put them into GPS mode using a DIP switch (except for the /G version of the DVM-7400). Is that the case with the DVM-8400?
A No. The GPS input is a dedicated input that is separate from the RS-232 port. It is always on, and always listening for GPS data. No need for configuration. All you need to do is connect a GPS receiver, and start a GPS playlist.
Q Is there a limit to how large my video files can be to play in the DVM-8400? 
A Yes, and no. The DVM-8400 uses the FAT32 file system, which has a maximum file size of 4GB. This means you cannot directly play a file larger than 4GB in the DVM-8400. However, you can divide this file into several 'chunks' using a file splitting program. As long as those chunks are named properly, the DVM-8400 will treat them as if they were one single file. No playlisting required, and no need to use Play Next. See the Media Files section of the DVM-8400 manual for details. 
Q I'm replacing a DVM/HD with a DVM-8400. Will the same videos play in the DVM-8400 without conversion? 
A Most likely. In addition to several other formats, the DVM-8400 plays MPEG2 Transport Streams (just like the DVM/HD). There are only two cases where the files would not play as expected. First, the bitrate of the videos must not exceed 40Mbps. The DVM/HD supported a maximum bitrate of 50Mbps, so this is a possibility. The second thing only applies if you are using the analog outputs of the DVM/HD and the video files have 2-channel Dolby Digital audio. The DVM-8400 will only output Dolby bitstream formats from the Digital Audio connector, so the analog outputs will be silent.
Q Can I use video files from the Digital Binloop HD in a DVM-8400? 
A Yes. The DVM8400 can play the same files as the Digital Binloop HD without any conversion required.
