What proper memory card should I use in Caltron’s Digital Signage Players?

CF cards and SD cards are widely use in the market

Caltron’s Digital Signage Players accepts different brands of Compact Flash (CF) cards and Secure Digital (SD) cards from the market. CF card is one of the earliest Solid State memory cards offering comparable capacity and read/write speed. Even with more competitions, CF card still have strength on some market, especially in digital signage area that need faster transferring speed like 30MB/sec. SD card is another popular storage device widely used in hand-held electronic devices. SDHC (High-capacity SD) card extend maximum storage capacity up to 64GB and can currently read/write speed up to 30MB/sec.

Memory Card Compatibility

Caltron is unable to test all CF cards and SD/SDHC cards from the market, theoretically, faster labeled cards are better. There are many free speed test programs you can download from the Internet, programs such as HD_Speed that tells you the read and write speed. Various manufactures produces cards that are unique to their own. The best way to make sure if you have selected the right card is to get an evaluation card from the supplier and perform a test run in one of Caltron’s player with the idea contents playing continuous for 10 to 20 days. Current Caltron players support up to 8GB on both CF and SD cards.

USB Port

All of Caltron’s digital signage players have USB port; however, Caltron does not recommend play contents from the USB drive. It’s due to the USB transfer speed being lower than the SD and CF cards. Displaying still images or lower bit rate videos maybe fine, but not recommend for the bit rate files over 1MB/sec. The main function of the USB port on the players is for transferring files to CF or SD card to update contents.
