Extron Electronics GSS 100 User Guide - Manual (Page 8)

User-selected images, including the test patterns, can be uploaded to the GSS via its
Ethernet port using HTML pages built into the GSS. The pass-through RGB input and the
output are via female BNC connectors.
The GSS provides 16 MB of RAM for storage, providing room for up to 17 uploaded bitmap
images. The number of images that the GSS can accommodate depends on the resolution
of the images. Table 2 shows the number of BMP images that the GSS can accommodate,
based on several common resolutions.
Table 2. Approximate Image Space for BMP Files
Resolution 640x480 800x600 1024x768 1280x1024 1400x1050
Size 900 kB 1400 kB 2400 kB 4000 kB 4400 kB
Image space 17 11 6 4 3
NOTE: Because of the variable compression schemes for JPG images, there is no reliable
method to calculate the number of JPG images that the GSS can hold.
• Progressive JPG images are not supported.
• Bitmap (BMP) images must be formatted as 24-bit RGB.
The graphic still store is housed in a rack-mountable, 1U high, half rack-width metal
enclosure. The internal 100 VAC to 240 VAC, 50-60 Hz, 15-watt, power supply provides
worldwide power compatibility.
